Hello, great project!
I tried to layout a class diagram but it seems to not consider the edge labels. Am I doing something wrong?

Hi Peter,

I believe I need more information. Smile

For starters, which drawing framework do you use to draw / edit your diagrams? Have you implemented your own DiagramLayoutConnector?

Cheers,
Christoph Daniel

Hello Christoph,
sorry should have added that. I use Papyrus and this connector

http://git.eclipse.org/c/papyrus/org.eclipse.papyrus.git/plain/extraplugins/elk/org.eclipse.papyrus.infra.gmfdiag.elk/src/org/eclipse/papyrus/infra/gmfdiag/elk/

Edit:
I debugged a little bit. The issue seems that in the layered algorithm. The EndLabelProcessor does not iterate over the layerlessnodes.

Greetings Peter

Hi Peter,

at the time the EndLabelProcessor is executed there shouldn't be any layerless nodes.

Could you do me a favour and export the layout graphs? Our website has some information on how to enable debug files and where they will end up. Could you activate those, execute layout once, and post the files somewhere?

Cheers,
Christoph Daniel

There was a bug in the configuration of the processors in the release. It should be fixed on the current master.

Oh, that's interesting. I only looked at the current master and couldn't see anything wrong with it, but had forgotten all about the pull request. That will be fixed in 0.2.1 once that is released (we haven't decided on a release date yet).
