DefaultConnectionEditPolicy not respecting scroll? [message #1740386]

Hi,

We, Fuse Tooling team, are implementing the insert of a Node on a Connection.
The cursor feedback was often disabled when there is a scrollbar on the editor.
From what I understood during my investigation, it seems that the DefaultConnectionEditPolicy is not taking care of the ViewPort Scroll.

I'm wondering if I'm right. Who is responsible to do the translation? The location of the CreateRequest? The DefaultConnectionEditPolicy when calling org.eclipse.graphiti.ui.internal.services.IGefService.findEditPartAt(EditPartViewer, Point, boolean) here http://git.eclipse.org/c/graphiti/org.eclipse.graphiti.git/tree/plugins/org.eclipse.graphiti.ui/src/org/eclipse/graphiti/ui/internal/policy/DefaultConnectionEditPolicy.java#n167 ? or directly the .IGefService.findEditPartAt ?

I am a bit confused. It seems very strange for me that this issue was not found by someone else before. In which case the DefaultConnectionEditPolicy is called exactly? i would like to check that I don't break anything. or maybe, I did something bad elsewhere which can explain my issue, in this case, does someone have some ideas?

You can see my PR trying to fix on my own project the issue: https://github.com/lhein/fuseide/pull/25

If I really found a bug, I can report a bug and provide a gerrit change.

regards and thanks by advance for any help

Aurelien,

indeed strange that this was not noticed before. I had only a brief look into these pieces of coding but from what I've seen so far, it looks like a bug to me. First of all, could you please file a Bugzilla against Graphiti to track this?

Regarding the responsibility for the location transformation: I would say it should be the responsibility of the edit policy, however that would force to include the fix in several locations (I have seen at least create and add using it). So it might turn out to be better in the gef service implementation. Anyhow it would be really great if you could come up with a proposal for the fix.

Thanks,
Michael
