I suspect you have a newer version of the BPMN2 modeller plugin installed. Version 0.7 of the tooling only supported version 0.1 of the BPMN2 modeller. The latest version of the tools, 0.8 nightly, was updated to be compatible with version 0.2.2 of the BPMN2 modeller. That said, the BPMN2 integration still needs to be updated to support the some of the changes made to the BPM integration over the last few releases (e.g. some of the property names exposed by the SwitchYard tools have changed).
Hope that helps.
Thank now work
I've installed all from scratch and insalled only the bpmn editor version 0.1
