[news.eclipse.tools.emf] problems with multi package ECD

[bdberry@xxxxxxxxxx (Brian Berry)]

My root ecd has two packages. when I generate the model it does not
properly or completely generate all of the code.  Also, I get the
following error when trying to open the resulting .genmodel: 

Problems encountered in the model
  The package 'platform:/resource/DISH/model/dish.ecore#//state' has the
same namespace URI 'null' as package
'platform:/resource/DISH/model/dish.ecore#//info'

I am using Omondo Eclipse UML plugin to generate my emf class diagram. 
Any suggestions?
