Hi, in my metamodel i have two metaclases that extend the operation class of the UML metamodel. These two classes have one attribute respectly and the type of the attribute of one of the classes is the other class...

The, in the model i know that the form of extract the default value of a attribute that belong to a stereotype is

optFunctionality.getValue(aste2, 'matchOpComponent')

when aste2 is the stereotyoe over the operation optFunctionality.

this return
org.eclipse.emf.ecore.impl.DynamicEObjectImpl@64b31700 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@4504d271 (name: Op_Component) (instanceClassName: null) (abstract: false, interface: false))

but i don't need that

I need the default value that must be the name of the other operation....

Hi

You invite us to help you with your metamodel that you do not supply. You do not identify which M2T tool you are concerned about. Perhaps Acceleo. Perhaps Xtend. The error message is a standard EMF message, more common in Acceleo than Xtend.
You assert that you know that some getValue expression is correct but then complain that the result is not what you want.
You will need to share much more information if you would like someone to debug your problem for you.

Hi

Details should be model files, not word files with (blank) pictures. You should enable the probvlem to be reproduced quickly: See https://wiki.eclipse.org/OCL/ForumNetiquette for relevant advice.

Hi

The figure 1 and 2 are in the attached files

In the Figure 1 you can see that the type of the attribute matchOpComponent is the Stereotype Op_component.

The figure 2 shows a model where the <<Op_Functionality>>RecommendedProduct in its matchOperation attribute has the value Op_Component[1]=getSuggestedProduct
I want to get the value of the matchOpComponent that in this case is "getSuggestedProduct".
To get that I am using the next instruction

optFunctionality.getValue(aste2, 'matchOpComponent')
where aste2 is the stereotyope over optFuctionality.

As result I am getting other value. How I can get the value "getSuggestedProduct" for this case.
