[news.eclipse.modeling.mdt.uml2.ocl] Re: Using OCL to specify derived Re

[JG <jguni@xxxxxx>]

I think I found one (of probably many) errors... I guess should not be
using the SubsetSupersetEObjectContainmentWithInverseEList for the
subset association (between Table and Columns) , but just a
SubsetSupersetEObjectWithInverseEList (i.e. no containment).
I am also not sure if passing a null for the feature id arrays is a good
idea, I replaced it with an empty array. Still, I now get
NullPointerExceptions when my code tries to remove content from a
container. The code in question is removing a content that is NOT a
column, i.e., is part of a relationship that I have not yet converted to
the UML2 ELists. Could this be a problem?
