CertWare fails to save changes in .gsz files

[assurance]

After creating a new .gsz file and developing an argument in it, Cetware fails to save the changes in that same .gsz file. Error displayed reads "Problem encountered in file"platform:resource/net.certware.demo/My.gsz" and "DanglingHREFException: The object 'net.certware.argument.gsz.impl.GoalImpl@33e09c64(identifier: G1.1, description: null)(assumed: false, toBeSupported:true) is not contained in a resource.""

This year we are deprecating the GSN, ARM, CAE, AML and EUROCONTROL models (both textual and graphical) in favor of the OMG's newer SACM metamodel. Changes currently are made on the 'sacm' branch. Our project won't update the GSN/GSZ models, but others are free to do this if needed.
