[qvtd-dev] [Dev] OCL Sets and java Util Lists
|
Hi Ed,
I have been running the UMLtoRDBMSSchedule.qvti transformation to find bugs in the transformation and in the engine. I am getting the following exception
java.lang.ClassCastException: org.eclipse.ocl.examples.domain.values.impl.SetValueImpl cannot be cast to java.util.List
when executing line 425 of the transformation:
atc.leafs := Set(AttributeToColumn) {atc};
In the QVTimperativeAbstractEvaluationVisitor class, the exception is thrown by the initValue method call (line 186).
I am guessing "Set(AttributeToColumn) {atc}" in the transformation returns a SetValueImpl when visited, and then the initValue tries to assign this value to the leafs attribute which is a java.util.List.
Is there some cast or helper method invocation missing in the initValue method, or does the Visitor must handle this?
(I have attached the complete trace).
Regards,
