Handling update conflicts

If you need to prevent concurrent changes from overwriting each other, you can add a version fieldFieldA property of a DataElement expanded to a database column and user interface input element..

This is a ValueField with type Integer or Long and option isVersion that keeps a version of an instance. When updating the instance in the database, the version will be checked to see if any other changes have been made since reading the current version.
