| How to make editor aware of model changes? [message #190735] |

Hello.
I have added a custom contribution item to the workbench toolbar when
one of my diagram editors is opened.
This item is meant to modify an attribute of my domain model when a
specific node is selected in the diagram.
In order to achieve this I have made my contribution item extend
PropertyChangeContributionItem and I have then created my own edit
policy, which extends PropertyHandlerEditPolicy and which returns a
Command of type SetPropertyCommand when its getCommand() method is
invoked.
Even though my domain model is modified as expected, the editor is not
marked as dirty and any listeners that I add to the domain model to
notify of model changes are not awakened.
What am I missing?
TIA,
B.

More details.
Upon careful debugging, I find that all goes well in my sequence of
messages until I reach a call to ViewUtil.setPropertyValue(). In this
method, nothing is actually done because the featureClass that is
passed in, which is my domain class that needs updating, is not
recognised as either a style or a layout of the view (node), nor is it
an instance of the view itself.
So how to add the property I am trying to change as something that the
view knows about? Or alternatively how to persuade the system to
perform the update anyway and to mark the editor as dirty?
TIA,
B.
