Object Property change is not reflected in the diagram [message #222506]

Hi,

I have a problem with making changes to the property view of the object
displayed on a diagram. Here is the case: OutPort node holds
non-containment references to InPorts (OutPort.TargetPorts). I have a link
mapping on TargetPorts. When I create InPort and OutPort instances and
links between them with tools, all the property changes are being added
just fine, but when I go from the other end - manually change properties
of OutPort instance from the Property View - and remove references from
TargetPorts, links on the diagram are not being deleted. I'd like to make
everything consistent - either delete the link on property change or
disable TargetPorts property editor in Property View. Any suggestions how
to do that?

Thanks.

Hello julsat,

This question was asked in a newsgroup dozen of times – try to looking for
an existing threads. In general the problem is – diagram update (implemented
in CanonicalEditPolicy generated for main diagram element) will not be called
on corresponding property change, so you have to modify generated code for
a link source EditPart and listen for an appropriate EMF notification. Manually
written code should call CanonicalEditPolicy.refresh() to update diagram.
