Copying BPM Processes

Working on the design of a large project i am designing BPM Processes in the latest  JDeveloper 12.1.3 with the BPM addon.

I had the need to copy a process in order to make a similar one, and i found an option by right clicking on the process:

Yet on selection it Fails:

???
The work around i found is 'Notepad'!!!

• copy the source .bpmn file with a new name
• Open with Notepad and find and change the process name and id attributes with the new name and id:

Then if you Refresh the folder in Jdeveloper the new process is visible and editable.

An other issue that i have is with Sub-processes. If you expand and collapse them the layout is usually distroyed and if you generate process image it always displays expanded:

So i try to avoid expanding and use print screen and crop for the image.

The devil in the details...
