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 Sinisa.
At
http://wiki.eclipse.org/GMF_Tutorial_Part_2#Mapping_Definiti on_3
is a description, that should help you.
To you the most important is probably:
"In fact, whenever you create multiple mappings to a single domain
element, you will need to add constraints such that each can be uniquely
identified."
Cheers,
Mark
PS. Of course, you could alter your meta model to have distinguishable
elements (like I did to solve the problem).
