Hi,
I have a problem if I'm using shortcuts. The scenario is the following.
I have a class 'Container' which has containment references to classes
'ClassA', 'ClassB' and 'Connector'. Futhermore, class 'Connector' is a
map entry with key of type 'ClassA' and value of type 'ClassB'.
I created the GMF diagram in the following way: 'Container' represents
the diagram, and I can create two types of nodes, 'NodeA' (for
instances of 'ClassA') and 'NodeB' (for instances of 'ClassB').
Instances of class 'Connector' are represented as arrows going from
'NodeA' to 'NodeB'.
When I'm using a single diagram, it all works as expected. The problem
arises if shortcuts are involved.
Example
-----------
Diagram diag_1 contains 'NodeA_1' and 'NodeB_1', which are connected
with an 'arrow'. Furthermore, it contains 'NodeA_2' (which is not
connected to anything). Thus, the underlying resource contains two
instances of 'ClassA', one of 'ClassB' and one of 'Connector'.
Now I create diagram diag_2. In this diagram, I create 'NodeB_2', and I
add a shortcut to 'NodeA_2' which is defined in diag_1. Then I draw the
connection between these two nodes.
PROBLEM: the instance of 'Connector' (the arrow between 'NodeB_2' and
the shortcut of 'NodeA_2' is created in the underlying resource of
diagram diag_1, instead of the underlying resource of diag_2.
Am I missing something? Shouldn't new instances be created in the
diagram in which I 'draw' them?
All the best,
Marc

Hi,
I've just found the solution. I had to overwrite method
private static MetricLibrary deduceContainer(EObject source, EObject target)
in generated *CreateCommand.java
All the best,
Marc
