Change in the model would create a different EditPart in the EditPartFactory [message #156095]

Hi All,

I'm currently facing the following problem:

My EditPartFactory decides which EditPart to create based on certain
conditions in the model object.

Now - if I change my model using the properties view it might be necessary
to create a different editpart.

Calling refresh() on the editpart or parent edit-part obviously does not
solve my problem since it always reuses the existing editpart.

Creating a new model object instead of changing the old one introduces even
more problems since the object that was just changed in the properties view
ceases to exist!! (when the framework tries to restore the selection on the
edit part I get a lot of ugly exceptions)

Can anybody please give me some hints of how to solve this?

Thanks a lot,
Martin.

Perhaps this might work: the parent editpart could first invoke
removeChild(childEditPart), before invoking refreshChildren().
