Cause
This error occurs if the collection description is incomplete or inconsistent.
When a
Action
Check that the class definition of the collection that is referenced is complete; for example, if it is a dictionary, check that its keys are correctly defined.
If JADE allows you to define a collection with an incomplete or inconsistent description, this is a fault in the JADE software and should be reported. If your JADE licenses include support, contact your local JADE support center or JADE Support.
