Hi,
I don't really understand your answer. The code that you wrote is
already implemented, right? If not, where do I have to add that code?
Perhaps some more information for better understanding my problem:
I create a new Property Tab which has a Property Section. The Input of
the property section are EditParts. After I add this information in the
plugin.xml, I create a new section class and a new class which
implements IPropertySource. I register the propertyDescriptor of type
PropertyDescriptor (I didn't create my own PropertyDescriptor). To
change the value in the property view, I override the method
setPropertyValue. There is the only place where I set the value of the
property.
Do I need my own propertydescriptor or a celleditor or something else?
Thanks.

Well yes, normally this all works because of this code.

So you have something different than just the normal generated
properties view, which was working.

It sounds like you aren't using commands to change the value and of
course the above refresh depends on using a command to change the value.

I don't know what you did to override setPropertyValue. Again, normally
you'd not have to override anything and it would all just work because
you'd uses EMF's implementation to support IPropertySource...
