Papyrus: Error exporting diagram as an image file

Question

This problem refers to an Eclipse Kepler instance running on Ubuntu 12.04. I have a Use Case diagram that I need to include in a document as an image file. I right click on the .di file, select Export All Diagrams... and then select PDF as the file format. In return I get an error window with the following:

ExportAll report

Reason:
Generation failed for some tests

In the error log an exception is filed:

Message:
error during generation of diagram NewDiagram in resource platform:/resource/EMS-iGUESS_Components/models/UseCasesNew.notation

What is wrong here? How can I export the diagram as an image file? Thanks.

Answer 1

I found that some elements (like Actors, ReceiveSignal) didn't accept a negative value for the Line width field. On these elements, you can replace the "-1" value by "1" in Properties / Appearance / Line width field.

Hope it helps...

Answer 2

Export it as an SVG file. You can view them in a browser and convert them to other formats later
