Greetings all,
I am having a problem getting my EMF-generated PropertySource to work well
with the Property Sheet when GEF's UndoablePropertySheetEntry is being
used as the underlying model for the PropertySheet.
I have a GraphicalNodeEditPart which is using an EMF model as its
underlying data model. EMF is generating an IPropertySource for me via an
adapter generated by EMF.Edit. My GraphicalNodeEditPart implements the
IPropertySource interface through the IAdaptable interface (which
UndoablePropertySheetEntry calls automatically when a selection-based
property sheet is loaded for a GEF object).
The property sheet loads the initial data just fine, but I go to edit it,
two problems occur:
1) If the underlying type is a boolean, a ComboBoxCellEditor is returned
by the EMF PropertyDescriptor and when I select the combo box sometimes, I
get an exception trace item 1 below. The exception is being generated
inside EMF generated code, seemingly because UndoablePropertySheetEntry is
trying to a "set" on the property before a valid value has been selected
in the combo box.
2) If the underlying type is a String, a default TextCellEditor is
returned by the EMF PropertyDescriptor and when I select the text box to
edit (always), I get a ClassCastException like item 2 below. This one may
be a EMF issue, but seems to be caused by the fact that EMF code assumes
an unwrapped eData object whereas UndoablePropertySheetEntry is passing a
wrapped one.
Any ideas or workarounds? I can't seem to find any bugs against this...
Configuration is: Eclipse M8, GEF 2.1.3 and EMF 2.0.0 I200405060858
Thanks,
Cameron

Eclipse 3.0 M8? Have you tried a 3.0 build of GEF?

I recommend writing your own custom implementation of IPropertySource.
Open a bugzilla, we can consider changing the undo behavior of
SetProperty...Command.

Hmm... 2.1.3 is listed as the latest release on the download page...
would I be looking for a "current integration build" then? It's not clear
to me from the download page which ones are version 3.0.

http://download.eclipse.org/tools/gef/downloads/drops/I-I200 40401-200404010005/index.php.
You'll see it says Requirements: Eclipse build 3.0M8.

Aha, thanks I'm not up the correct level. Well, the problem with the

Thanks,
Cameron

The workaround is as follows:
1) In your GraphicalEditor, override the getAdapter() method to include
support for IPropertySheetPage and have it return a default
PropertySheetPage with the PropertySource set to your EMF adapter's
adapted property source.
2) In each GraphicalNodeEditPart where you want on-click property page
support, implement the IPropertySource interface directly and have each of
the interface method calls simply proxy the underlying EMF adapted
property source calls.
This seems to work, although it has the one drawback that the Undoable
property sheet is not being used.
