allSubobjectsOfType works with some types. [message #1837491]

Hello,

I am using a KDM instance and I create some queries.

When I use this code:


self.allSubobjectsOfType(code::CodeElement) -> forEach(r){
			
			r.codeRelation[Extends] -> forEach(q){
					
				log("Extends: "+q._from.name + " -> " + q.getTo().name)
			}
	}

The ouput is empty. The problem is that the function does not get types of code::CodeElement, and I dont know why, because it works with other types, for instance MethodUnit, StorableUnit and others.

The xmi is too big to attached it.

Thanks,

Daniel.

Hi

Could you please attach the full QVTo project?

Please create a minimal version that demonstrates the problem. Otherwise it will be really hard to find out what goes wrong.

Kind regards
Christopher

Hi

Are you sure that you did not mean allSubobjectsOfKind? looks like the same gotcha whereby oclIsType is almost plays a bug. Ditto in Java; xx.getClass() == XX.class rather than xx instanceof XX.

Are you sure that [Extends] is not filtering out all possibilities?
