Hi,
I have an element A that can contain several elements B. I would like to
distinguish B elements : B0 and B1. B0 and B1 are domain model B
elements but they will be intialize differently. So, in my palette tool,
I would like to have 2 different items : B0 and B1.
My .gmftool contains :
...
B0 item
B1 item
My .gmfmap contains :
...
NODE A
Compartment BElements
Child Reference
NODE B ---> B0 item tool
Child Reference
NODE B ---> B1 item tool
When I launch my diagram, the palette tool effectively contains 2
different items. One item correctly creates a B element, but the other
throws an error when I want to create the element on my compartment :
org.eclipse.core.commands.ExecutionException: While executing the
operation, an exception occurred
I suppose that I have to modify my .gmfgen file... but I don't know
where and what ....
I have an other question : I would like to display a different
properties view content according the type of my Element B : how can I
do that ? (which are functions to change ? Where...)
Thanks for your help!
Best regards,
Philippe

Arf, you are right Alex.
Tutorial 2 says : "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.".
Thank you very much !
