Hi,

If I write the below ATL code, I have the error "org.eclipse.m2m.atl.engine.emfvm.VMException: Feature method does not exist on PropertyCallExpression".

helper context MM_ETL!Expression def : collectWithFeatureFollowing() : Boolean =
if ((self.oclIsTypeOf(MM_ETL!PropertyCallExpression) or thisModule.isAHelper(self)) and not self.oclIsKindOf(MM_ETL!FOLMethodCallExpression).oclIsUndefined())
then if (self.method.name = 'collect')

if I change the code to the below code, I have the error "org.eclipse.m2m.atl.engine.emfvm.VMException: java.lang.Boolean does not have properties".

helper context MM_ETL!Expression def : collectWithFeatureFollowing() : Boolean =
if ((self.oclIsTypeOf(MM_ETL!PropertyCallExpression) or thisModule.isAHelper(self)) and not self.oclIsKindOf(MM_ETL!FOLMethodCallExpression).oclIsUndefined())
if (self.oclIsKindOf(MM_ETL!FOLMethodCallExpression).method.name = 'collect')

what can I do to access method?

Hi

It seems the wonderful FUDforum software is selective in its RSS notifications, so good that you pinged.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=513124 raised.

But providing partial examples is not going to allow anyone to offer much sensible help. I can only suggest you read the error message and selectively simplify.

Regards
