Using types from additional MetaModels [message #1700145]

Hi,

I write an editor for a model that can be extended. Some objects in my metamodel have an URI attached that points to an EObject that I want to display in the diagram. The corresponding boxes get displayed but I cannot execute any queries on them. I get this error message from Acceleo:

!MESSAGE Compilation error for expression [self.getEntityName()/] : Cannot find operation (getEntityName()) for the type (Role)

The Metamodel is registered in the EPackage.Registry.INSTANCE and it is a normal ECore Model so I don`t think I need to register any additional factories.

What do I need to do for my expressions to be compiled successfuly?

EDIT: The plug-in which defines the additional MetaModel is registered in my MANIFEST.mf as a dependency.

I fixed this issue now, the mistake was calling the getter instead of accessing the field directly.

However I have trouble with the elements with deletion commands. I have external java commands defined for removing the objects but I this exception:

java.lang.RuntimeException
	at org.eclipse.sirius.tools.api.interpreter.InterpreterRegistry.getInterpreter(InterpreterRegistry.java:70)
	at org.eclipse.sirius.tools.api.interpreter.InterpreterUtil.getInterpreter(InterpreterUtil.java:39)

	at org.eclipse.gef.editparts.AbstractEditPart.getCommand(AbstractEditPart.java:502)

The problem seems to be that the object is not part of the models associated with the current Session. I tried to work around it this way:

SessionManager.INSTANCE.getSession(parent).addSemanticResource(child.eResource().getURI(), new NullProgressMonitor());

But I still have the same error.

Hi,

After adding the resource containing the object that caused the
exception, you should have no longer the problem.

Is the modelElement of InterpreterRegistry.getInterpreter (in stack
trace) in the same resource as the EObject named child in your code
(SessionManager.INSTANCE.getSession(parent).addSemanticResource(child.eResource().getURI(),
new NullProgressMonitor()))?

Regrds,

Laurent
