ELK Use with GmF [message #1814519]

Hi,

i have diagrams based on gmf and draw2d objects, i am having difficulties including elk correctly into my project,
There is an already implemented version for gmf from Uni kiel in Germany
https://github.com/eclipse/elk [is plugin org.eclipse.elk.conn.gmf the only relevant plugin in this case]
The instaliation of elk in eclipse is a simple matter, but adding the plugin i need is tricky as well as multiple contradictory Extention points because even after spending hours adjusting code i am still getting ERROR no layout connector available for (IWorkbenchPart )name.
But the documentation is very lacking as well as my experience in RCP.

Any input appreciated.

Yes sir I did multiple times even. And i used the already written org.eclipse.elk.conn.emf plugin where those functions from the documentation that need implementation are already there. I have an already finished project with diagram.ui and wanted to at least see the layout view of ELK. From documentation it says that Calling DiagramLayoutEngine.invokelayout() is the step to take to connect with Layout view.
I have copied org.eclipse.elk.conn.gmf/org.eclipse.elk.core/org.eclipse.elk.core.ui/org.eclipse.core.service/org.eclipse.elk.graph and adapted the plugins in my project.
What am i missing ?
Should they be added as plugins or maven modules?
Thanks.
