Hi, I'm currently working on some GEF editor and can't find a way to dynamically change EditPart figure. Sad

I have an

org.eclipse.gmf.runtime.diagram.ui.editparts.ShapeNodeEditPart

object. While org.eclipse.emf.common.notify.Notification event come, then

org.eclipse.gef.editparts.AbstractGraphicalEditPart.refreshSourceConnections()

method is invoked on my ShapeNodeEditPart object. It means that my node on diagram was connected to some other node. In this moment I would like to change my node figure.
I was trying to invoke

unregisterVisuals();
IFigure figure = customEditPart.createNodeFigure();
figure.setBounds(getFigure().getBounds());
setFigure(figure);
registerVisuals();

It doesn't seem to work. There is the same figure displayed but little bit shifted depending on bounds.
What is the correct way to do this?
I would be grateful for any tips.

Node figure before event came:
index.php/fa/16935/0/

Node figure after event came (above changes):
index.php/fa/16936/0/

Node figure after event came (expected):
index.php/fa/16937/0/

Hi, you should update your part's visual representation in AbstractEditPart.refreshVisuals().

If you need to remove an existing part and replace it with a new one, then I think it's its parent responsibility to do that.
You have to change the list returned from parent's getModelChildren() method and call refreshChildren()
or call removeChild(EditPart child) and addChild(EditPart child) for more efficient way.
