Hi, I have a following problem. Smile

I have an arrow label that is movable vertically along arc from the beginning to the first bendpoint. I achieved this by overriding

XYLayoutEditPolicy.getConstraintFor(...)

method for REQ_MOVE_CHILDREN and REQ_RESIZE_CHILDREN requests. When I create new label it's not connected to arc.

After I connect it it's repainted (the way described here - http://www.eclipse.org/forums/index.php/t/628027/) but it stays in the same position.
index.php/fa/17184/0/

When I move the figure it will correctly move to the arc - REQ_MOVE_CHILDREN request isgenerated and getConstraintFor method recalculate arrow figure location.
index.php/fa/17185/0/

I want to achieve this right after connecting label to arc. I thought I can generate fake REQ_MOVE_CHILDREN request to move arrow figure to arc. How can I generate fake REQ_MOVE_CHILDREN request? Is there a better way to do this? Can I update figure location in
