Hi,
I have a problem using the same ECORE class with different creation
tools. Let's assume there is a (diagram) class A, referencing class B
twice: via EReference b1 and b2. Let's further assume there is one node
in graphical model and two creation tools (B1 and B2) in tooling model.
In mapping model I created the following:
Top Node Reference
Containment Feature: A.b1
Element: B
Diagram Node: Node B
Tool: Creation Tool B1
Top Node Reference
Containment Feature: A.b2
Element: B
Diagram Node: Node B
Tool: Creation Tool B2
Code generation succeeds, but: If you use the B2 creation tool (in an
newly started eclipse application), an exception is thrown (see below)
and no B element is created.
------------------------------------------------
Caused by: org.eclipse.core.runtime.AssertionFailedException: null
argument:failed to create a view

at
org.eclipse.gmf.runtime.common.core.command.CompositeCommand .doExecuteWithResult(CompositeCommand.java:403)
------------------------------------------------
Using debugger, I could find the origin of the above mentioned
AssertionFailedException. In class
org.eclipse.gmf.runtime.common.core.service.ExecutionStrateg y
there is a static final attribute 'FIRST' of type ExecutionStrategy,
implementing method
public List execute(Service service, IOperation operation)
This method returns Collections.EMPTY_LIST, causing its caller to return
null.
I don't know how to proceed further. Anyway, do you have any suggestions
how to make the example work? BTW, used models are attached to this message.
Cheers,
Mark

Hi Mark,
I think that you need to set constraint on the different node, on
containment feature for instance.

Hi Mark
Thanks for response.
This link is exactly what I need.
I also need to alter meta model because my ECORE element doesn't have
appropriate attribute.
Also, I am not familiar with OCL syntax,
so I will try to create a Constraint with the Java syntax.
Again, thank you very much.
