[news.eclipse.stp] BPMN - Adding a new property for sequence edges

[svenkuehner@xxxxxxxxxxxxxx ( Sven)]

hi :)

I'd like to add a new property (in the property view) for sequence edges 
in the BPMN-program.
Unfortunately just editing the ecore-metamodel bpmn.ecore, extracting it 
into bpmn.ecore_diagram and running the whole code as an eclipse 
application doesn't work.

Has anyone an idea oder can tell me how to do that?

Many thanks in advance!

Sven
