[ATL] error with oclAny [message #79200]

Hi all,

I try to copy some classes from a profiled source model to the target
model. I get this error

SEVERE: ERROR: get unsupported on OclAny.
java.lang.RuntimeException: ERROR: get unsupported on OclAny.
at
org.eclipse.m2m.atl.engine.vm.SimpleDebugger.error(SimpleDeb ugger.java:195)

Is this error means something wrong in my transformation code or a plug in
is missed.

Thanks very much in advance for your help.

Thanks William. The problem was in the getValue() method. I fixed the type
for its arguments. But I have another error

SEVERE: ****** BEGIN Stack Trace

I think the problem is in these helpers as the rest of the code works fine
without them.

helper context UML!"uml::Element" def: getTaggedValue(stereo :
String ,tag : String) : UML!"uml::Element" =
self.getValue(self.getAppliedStereotype(stereo),tag);

helper context UML!"uml::Element" def : checkMyPropertyValue() : Boolean =
if (self.hasStereotype('MyStereotype')) then
if (self.getTaggedValue('MyStereotype','myProperty')-> exists (s| s.name
<> 'value1')) then ...

Any hint will be great,

Rasha
