Cause:
TIBCO ActiveSpaces uses the property name "id" to store the internal entity id (@id, backingstore column name $id). It is not allowed to use "id" as a property name.

Two CR's have been raised:
CR BE-20043 - update the manual and add "id" to the list of reservered words
ER 20045 - disallow attribute name "id" in studio
