I tried to change the model for the GEF 6 sample.
I added a selection pane entry to add a new node.
Basically it works 'fine', but I don't know how to refresh the view to see
the
added node element.
When I debug the model I see my newly added EditPart in the Model (the
Model now has an ArrayList not the fixed size Vector) but the added node
doesn't show up in the actual view.
How does the Framework works? Is there some more documentation available?
I can debug thru GEF, but that can't be the solution in order to get
familiar with this framework.
Perhaps somebody can help?
Heinz

This is non-trivial, depending on the flexibility of such labels.

We are currently looking at reworking the context menu. See
contextMenuProvider for now.

Read the workbench documentation on the property sheet and IPropertySource.
AbstractEditPart is IAdaptable, and will implement getAdapter properly.
Look at the model in logic example.
