You might find it easier to not use the EMF-generated properties and just
create your own, that will work better with GEF. If you must, however, then
check out the EDiagram example with the tag "oldProperties."

Hi Pratik,
I thought I oversaw this example, but some weeks ago I posted a question
"why is org.eclipse.gef.ui.properties.UndoablePropertySheetEntry final?".
The reason was, that the ediagramm example does not work with the
current version of GEF.
The reason, why I want to use generated properties is, that I did not
find a way to create properties for EReferences. EMF generates a really
nice dialog, where you can add multiple elements to your model.
I did not find a way to use this dialog. So if you (or someone else)
ould give me an hint, I could solve this or I have to switch back to an
older version of GEF (and maybe stay there..)
The ediagramm example seems not to use this dialog. There you implement
your own dialog and this is quite difficult for me.
Andreas

Yes, unfortunately, that tagged version of the example works with an older
GEF version. You can open a feature request to have
UndoablePropertySheetEntry be not made final.
