Hi,
Currently, if the user selects the begin/center/end label of an edge, they can't edit it directly. Consider the user just needs to change the multiplicity of the roles on an association, they can't !
Is there any way to capture double click or edit of the begin/center/end labels ? I think this would be very useful if we could have it.
Thanks,
Parsa

This is a known limitation, but fixing it is actually a more involved
that it looks, so it is not planned for now.
In the meantime you can use the same technique as used by UML Designer,
which provides its own custom edit parts for these labels, with an
additional edit policy. See http://bit.ly/224QGrZ.

Thanks Pierre, I could make it work, So, I write the steps I took if anybody else has the same problem as me !
1- Add the following lines to your plugin Activator class:
private ICommonLabelProvider labelProvider = null;
/**
* Returns the label provider to use for displaying locked elements.
*
* @return the label provider to use for displaying locked elements.
*/
public ICommonLabelProvider getLabelProvider() {
if (labelProvider == null) {
labelProvider = new SiriusCommonLabelProvider();
}
return labelProvider;
}
2- setup an extension for org.eclipse.gmf.runtime.diagram.ui.editpartProviders which points to the UMLEditPartProvider class.
3- Add the following code in the body of your UMLEditPartProvider class. Note that this class should be adopted it to your needs:

4- Add an editlabel in the .odesign description for the association/composition/aggregation or whatever edge you have !
5 - make a dummy java service method and set the edit label run the java service. (Simply in your editlabel add a "Change Context" element and run the service). Also don't forget to map the editlabel to your association edge.
6- Run/Debug !
Cheers,
Parsa
