Exporting Concept Model to OWL Ontology

[jadeira.lu@rockwellcollins.com]

I have Cameo Enterprise Architecture and do not have the concept modeler plug-in installed (if that matters) but am trying to export a concept model into an OWL ontology format.

I keep getting this error: ERROR [com.nomagic.conceptmodeler.ui.Cameo Concept Modelern:169] - Following unexpected error occurred while trying to export the package: 'str cannot be null' and am unsure why??

I removed all spaces in the element and package names and am using either '_' or '-' in their names. I also set all of the highest level packages to have the same URI that was initially generated when I created the concept model. I'm not sure what I'm missing but I have not been able to successfully export my concept model to the OWL ontology format. Thoughts?
