Tabbed property sections are sometimes not activated. [message #753760]

Hi,

I am facing a strange problem with the tabbed property sections:

When opening a diagram and clicking through the diagram elements the property sections are activated correctly
After adding elements (nodes, transitions) to the diagram the property sections still are activated correctly
After changing domain object properties in the property sections the sections are NOT activated correctly anymore (actually they are not activated at all, i.e. the properties view only says "Properties are not available")
After closing and reopening the diagram everything works perfectly again until the procedure is repeated

Did any of you have a similar problem in the past?

Best,

Georg

Georg,

at I first glance I would suspect an issue with using the wrong editing
domain. Did you have a look at our FAQ entry on property sheets? See
http://www.eclipse.org/graphiti/developers/faq.php.

HTH,
Michael

Thanks for pointing me to the FAQs page. Before I was using the standard EMF editing domain and command API for making changes on the domain model. Now I use the Graphiti IFeature API instead.

However, this modification did not solve the problem. Nevertheless I managed to get around it: Previously I was setting the SelectionProvider to be a TableViewer contained in the PropertySection. That was the reason why the diagram editor selection were not forwarded anymore.
