When I create a displaygroup with the component editor and then switch to the source view of the displaygroup, the entity is not recorded in the file resulting in the following error message at run-time.

[java.lang.IllegalArgumentException] There is no model containing entity 'null' in the default model group. Unable to create EODatabaseDataSource.:java.lang.IllegalArgumentException: There is no model containing entity 'null' in the default model group. Unable to create EODatabaseDataSource.

Either selecting the entity from the popup or typing it does not work. Unless you type a few characters more and then then hit backspace ! then it seems to come alive !

It also seems to have a lot of random consequences causing various validation and run-time errors.
