AW: AW: AW: AW: AW: AW: [ve-dev] Overriding the Property-EditorinaSubclassdoesnotseem to work 
Hi Rich!

By adding a custom BeanPropertySourceAdapter I can hide
"the unwanted text property" and it is not displayed in the property-sheet.
Thanks.

The problem afterwards is that I'm editing the wrong text property
(RButton-text instead of ULCAbstractButton-text) and my GEF view 
is not updated (it's somehow binded to the other property).
Something like that, I don't know exactly...


After spending hours and hours to get it work and still not succeeding, 
I'm frustrated and I forget now the idea of overriding the property editor. 
Instead I'll patch the original .override files (e.g. String.override) which 
is much easier and for more efficent.

Thanks anyway & best regards,
Peter

Hi Peter,

Yeah, I was afraid of that. :-(  Both features still exist on the EMF 
class. It is just that when you look up the feature by name it will find 
the first feature from the bottom up, which means it finds the one from 
your subclass when lookup by name.

I think you may need to also supply a PropertySourceAdapter implementation 
for your RButton that inherits from BeanPropertySourceAdapter, and it 
overrides just one method:

protected boolean includeFeature(EStructuralFeature sfeature) {
 
        // Do not include the "text" feature from the base ULCBean.
        if (sfeature.getName().equals("text") && sfeature.
getEContainingClass().getName().equals("ULCButton")
                return false;
        else 
                return super.includeFeature(sfeature);
}


Thanks,
Rich

Hi Rich!

Thanks for your patience with me and your help.

You were right, I forgot to declare 2 namespaces in the header...

I think, we're getting closer... I have now the
funny thing that I have TWO "text" properties in the
property sheet for my RButton instance 
and on the first one I've got my editor! :-) (see attachement).

any ideas ?

best regards,
peter
