Changes and improvements​

Upgrade to Angular 19 and Angular Material 19​

For this release we updated all the code to Angular 19, in order to stay up to date with the releases and best practices.

Separation of QuerySearch​

QuerySearch is now an addon, instead of the default filtering implementation. Everything related to filtering in the code has been moved to separate expansionResources, namely angular-querysearch-expanders, angular-svcapi-querysearch-expanders and angular-stdapi-querysearch-expanders. When these expansionResources are not added the application will still function, however the filtering capabilities will not be present. From now on you can also add filtering implementations, e.g. finders, or provide a custom one.

Yarn support​

We provide a solution to substitute npm with yarn if wanted. This drastically improves dependencies install times. Substitute the Std API profile with Std API yarn (or Svc) in your expansionSettings.xml.

Harvest expanders​

The angular-expanders now depend on the harvest-expanders:1.0.0, this is an example of one of the first expansionResources that contains reusable expanders. These expanders and expansion steps define the gen/ext less harvesting.

New design implementation​

This version contains the new designs made for the list and details page.

Migration guide​

Program folder refactor​

In order to accommodate multiple AngularApp instances, a folder structure similar to Application has been adopted. This means that in the angular folder you should relocate the ext, harvest and model folder present to a subpath /angularApps/{angularAppName}. You should not move the featureModules folder.

angular
├── ext
├── harvest
├── model
.   └── space-app.xml

angular
├── angularApps
.   ├── space-app
    .   ├── ext
        ├── harvest
        ├── model
        .   └── space-app.xml

Changed allowed value of option angular.isLinkFilterField​

The expanders were refactored to correctly find the required DataConnector in the available dataConnectors of the AngularApp. A new find algorithm has been put in place to do this, this algorithm does not rely on the DataRef anymore. This is why the value of the option has been changed to only the name of the DataConnector.

featureModuleName::dataConnectorName

Branding​

Login component​

Due to popular request the generated login component can be fully customised when using the option angular.hasCustomBranding. This will now give you custom anchors in the login.component.html and login.component.scss files, instead of only the option to change the images.

Title tag in index.html​

When using the option angular.hasCustomBranding, custom anchors will appear to set the title tag of your index.html. This is used in the browser tabs, when no other title is set via the angular router. When not filled in, it will put the url in the browser tab. Before the title was always angularAppName.

Version 3 of the nsx-tomee-base Docker image is now available. This version introduces (experimental) support for rootless containers, as well as some minor breaking changes.

Rootless​

New images have been added that can be used to run rootless containers. They add a new tomee user, which is used to execute the TomEE application server instead of the root user. Not running containers with a root user reduces security risks for the host system. All existing images are available as rootless as well under labels with the suffix -rootless appended to it.

Data volume​

The image now pre-defines a volume at the /data path for applications to write files to. The volume is pre-defined so it will be created even if it is not explicitly defined in the deployment of the container, so any files stored there will always be put into a persistent volume.

Scripts moved​

Previously all fixed scripts were stored in the /tmp folder. Though this is not ideal, we kept this for consistency and backwards compatibility. With this major version we've now moved those scripts to a new location in /scripts. There are still symlinks to the existing scripts in case they were called.

A brand-new release of the process-automation component is now available! There have been quite a few changes, mostly targeting stability, compatability and bug fixes. Some of the default configuration has changed, which may impact applications using a custom configuration. Read the migration guide below to verify if this applies to you!

Changes and improvements​

• (Stability) {DataElement}Cruds will now return an error when trying to modify an element into an interim state outside a Task.
• (Stability) Added error and recovery policies, allowing applications to configure how to deal with internal errors.
• (Stability) Fixed some issues which would occur when transactions went into timeout.
• (Compatability) Added support for applications using the ejb.interfaces.localOnly option.
• (Compatability) Replace usage of TransactionManager with TransactionSynchronizationRegistry. This should be available in more JavaEE runtimes.
• (Traceability) Added new monitoring anchors, to allow for more insight into applications running in production (more on this soon).
• (Performance) ApplicationPersistent queue will now fetch the queue much sooner if the last fetch received the requested number of tasks.

Changes and improvements​

This major release marks the beginning of data access (control layer) separation in the angular stack. This has been accomplished by expanding DataAccess interfaces and InjectionTokens. This token can be implemented by a separate expansion resource specific to a certain control layer implementation, e.g. rest-expanders, json:API, ...

For the moment two data access implementation resources exist:

• angular-svcapi-stack (rest-expanders)
• angular-stdapi-stack (jaxrs struts replacement)

REST Expanders are now capable of generating fully featured interactions with file resources. Several other fixes and improvements were also implemented. This post will cover many of the improvements introduced from version 4.22.0 to 4.26.0. The latter of which we consider to provide a complete and stable implementation of the file support.

Resources​

The expansion resource below provide rest-expanders 4.26.0.

Changes and improvements​

File support​

Version 4.26.0 of rest-expanders features the finished implementation for file support. This includes the linking of file resources to regular REST resources, endpoints to upload files and endpoints to download files.

Files are always represented as fields of a REST resource. It is possible to add the option svcapi.endpoint.upload to generate an upload endpoint in function of a field and svcapi.endpoint.download to generate a download endpoint.

An upload endpoint will return a header containing a unique identifier for the file that can passed to the resource endpoints to link it to a new or existing resource.

{
  "name": "Snickers",
  "uuid": "f9020d14-b1ab-4de3-99a2-f0a2e5a8c71d",
  "birthCertificate": {
    "resourceUri": "http://localhost:8080/restexample/v1/cats/f9020d14-b1ab-4de3-99a2-f0a2e5a8c71d/download/birthCertificate",
    "identifier": "d8227d40-4e8b-4b7f-baf4-52bb8a051e26",
    "fileName": "snickers-haz-cheeseburger.jpeg"
  },
  "breed": {
    "resourceUri": "http://localhost:8080/restexample/v1/catbreeds/Maine%20Coon",
    "name": "Maine Coon"
  }
}

Asset support​

A new expansion resource rest-assets-expanders was introduced which provides a default implementation for file links when they are represented by linkfields to assets:Asset. This includes an implementation for the upload and download endpoints. The rest-assets-expanders resource is now also part of the rest-jaxrs-stack resource.

Client aborts​

To round out support for files, the REST expanders now handle aborts for file uploads and downloads from the client. The API now returns nothing when these events occur rather than an error. A message will be logged on the server.

Strict finders​

There was a long-standing issue in the backend implementation for the API where in a few places finders are used that do not use strict equality to match resource identifiers. This has now been resolved by adding support instead for the same finders, but using strict equality operators. A strict not-equal operator was also introduced for this purpose.

Though the old finders using Eq and Ne operators instead of Se and Sne operators are still supported, the strict operators are now considered default and the non-strict ones only as fallback if they are the only available.

CORS support​

The support for CORS handling in the CorsFilterProvider class has been improved to now include the Access-Control-Expose-Headers, in order to whitelist headers returned by the server for use in scripts. New anchors exposed-headers are available to add additional headers if needed.

Better ValueType support​

While rest-expanders already provided support for ValueTypes, the AddDefaultRestApi transmutation still provisioned the model using the deprecated ValueFieldTypes. This has now been updated to correctly provision the model with ValueTypes instead.

Version 3 of querysearch is in itself not a major functional upgrade, but it is the first version with its model infrastructure depending directly on its ontology model rather than the old elements-based metamodel. This means that it is expanded using the ontology expanders.

Builders​

The querysearch-builders module no longer exists. If it is used in an expanders project, remove the dependency. The builders are now part of the querysearch-core module.

Migration guide​

@imports anchor​

Some expanders have been migrated to the new import system, see changelog for the list. This means that feature anchor for imports are no longer necessary and hence they have been removed. To add imports in these files you can add uses statements to the feature expander.

Name changes​

Some services have changed name to better comply to the guidelines or to better describe the functionality. This reflects in custom imports and need to be checked.

• dataConnector.service -> DataConnector-data-access.service
• dataConnector.datasource -> DataConnector-data-source.service
• dataConnector.filtersource -> DataConnector-filter-source.service
• dataConnector-infinite.datasource -> DataConnector-infinite-data-source.service
• .data models have been changed to .document.

Moved service injection location​

Instead of injection services in the constructor they are now injected as variables. This is also done using the new import system, which makes it easier to maintain. See changelog for the list of affected files. It also changed some of the injected names used:

• dataSource -> dataConnectorDataSource
• filterSource -> dataConnectorFilterSource
• route -> activatedRoute
• translate -> translateService

Mapping location change​

DataConnector models are not mapped in the DataConnector-data-access.service anymore, but have there dedicated mapping services now. If any customizations were added to these mappings, then the corresponding harvest code needs to be moved to the new mapping services.

Removed shared components​

The DropdownComponent and MultiSelectDropdownComponent have been removed and the use has been replaced with the select component from ngx-ns-core.

Default translation file​

The default translation file has changed from en.json5 to gen.json5. This one is used by default, but can be replaced with a custom one by using option angular.defaultLanguage on AngularApp. You should change the name of the harvest file to keep custom translations.

Functional key -> id​

In this version a refactoring has been done to not rely on functional key of the DataElement as a variable anymore, but use a generic id name. This impacts routes and method arguments.

Routes​

In places where you retrieve the id from the route, the name of the variable should be changed.

const id = this.activatedRoute.snapshot
    .paramMap.get('externalId');'

const id = this.activatedRoute.snapshot
    .paramMap.get('id');

Method arguments​

The method interface has been altered in places where the id of an element is needed to use id instead of functional key. This has been done to better comply to the id and displayLabel field added to all element models. This can be used with duck typing as well now.

getSingle({ uuid }: { uuid: string }): Observable<DemoElementModel>

getSingle({ id }: { id: string }): Observable<DemoElementModel>

Changes and improvements​

QueryValueType​

The QueryValueType enumeration is used to indicate the type of an object passed to a query constraint. Usually a developer will not interact with this, as every constraint factory method that takes it as a parameter, also comes with a variant that does not. In the latter case, the type will be inferred from the object that is passed to the constraint. This can only be inferred for known types, which is mostly primitives and java.util.Date.

As a default, when not recognized, the type would automatically be set to String, resulting into a conversion of the object to String in supporting constraints. With this update the type QueryValueType.OBJECT was added which handles the supplied object as a raw value that is passed directly into JPA, as this is sometimes desired.

Since converting to String is typically not intended behavior for objects that are not of that type, the default when a type cannot be determined is now QueryValueType.OBJECT. This is a breaking change, but should have very little impact, as currently, cases where unknown object types are passed to a constraint are likely to be unintended. In cases where this is intended, the migration guide will explain how to resolve this in the new implementation.

In the past six months we've seen adoption of the process-automation component. Feedback has been great and people seem to be happy with the changes we made. We felt the current feature set came to a point where it warrants a first stable release. This of course does not mean development will stop here, as there are many features we still plan to add.

Resources​

Feature set summary​

The list below should give you a good idea of the features we currently support through process-automation:

• Fully supports the workflow model.
  • Integrates all defined transitions, including branching transitions.
  • Respects configuration on TaskElements, such as transactionType and TaskOutcomes.
  • Supports configuring WorkflowImplementation through defining QueuedProcessors.
• Multi-node or multi-instance configurations are supported.
  • Internal state-machine to perform leader-election in the presence of multiple nodes.
  • Ensures smooth execution of transitions, with no conflicting state.
  • Improved scalability by providing extensible queue configurations.
• Event-based execution model, backed by a queue.
  • CRUD triggers: transition an element on create or modify.
  • Transition trigger: immediately queue the next transition after another completes.
  • DataCommand trigger: transition an element when a command is performed.
  • Schedule trigger: Cron-like configuration for time-based transitions.
  • FlowEngine trigger: behaves similar to the classic Flow implementation.
• Modular design, ships with standard configurations and can be extended easily.
  • Provided queue implementations: ApplicationPersistence (DB) and InMemory.
  • Provided processing implementations: Asynchronous and ExecutorService.
