[news.eclipse.modeling.mdt.uml2] Re: Problems to patrticipate in a Deriv

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Marc-Florian,

It would seem that you are looking for a DerivedUnionEObjectEList or 
DerivedSubsetEObjectEList.  The various SubsetSuperset lists are used when 
you want to automatically add to the superset when an element gets added to 
the subset but not vice versa.
I'm not sure if you are implementing these things by hand but specifying the 
various subset rules in the model and using the code generator to determine 
the best list may be easier.

Cheers,
- James.
