Best practice for updating graphiti Graphics from business object changes [message #904559]

Is there a guideline for updating the graphics when changes occur to a
business object. In the past when our team built GEF based EP's with an
associated EMF bo, we would create an EMF Adapter for the bo in the EP and
use Adapter.notifyChanged to refresh the EP or its children. What is the
best practice for the equivalent in graphiti?

Graphiti does this out-of-the-box for EMF models. We register a global EMF
adapter for an editor that reacts on domain object changes; it checks the
shapes on a diagram if they link to the changed domain object and in case
yes call an update feature registered for this shape.

This call might happen directly or indirectly depending on the editor update
setting (automatic update yes or no). See
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.graphiti.doc%2Fresources%2Fdocu%2Fgfw%2Fupdate-feature.htm&cp=22_1_3_2
for details on this.

HTH,
