Hi There,
I am really stuck with this one. Sofar I have been succesfully using the
Command Framework. The 'CreateChildCommand.create(...)' works well and
the UI gets updated very nicely.
Now further on, I have this feature of EDataType which is basically a
EList<String>. which is edited by a text editor, in a separate workbench
editor. (Customized text editor to work with this feature only).
I can't use 'CreateChildCommand.create(...)' to update this datatype, so
I use the 'SetCommand.create(...)', the command executes correctly, I
verify the new List is indeed correct. ( I use the EditingDomain from
the EMF Editor).
Now when I switch to the EMF Editor and look in my propertyView of the
EMF Editor, the value hasn't updated. (It hasn't updated in any of the
views i.e Outline or any of the table, tree etc... viewers).
I do see a notification is received in the item provider, I also see the
EMF Editor is marked dirty (So it was notified). Interrestingly, when I
save the model, my changes which are reported changed correctly in the
model, are not reflected in the file on disc).
So to troubleshoot, I would need to know.
- Is it needed to explicitly notify the views when working on the model
with Commands from another editor? (Wouldn't the views refresh/update
when becoming visible?).
- How can it be that a command executes correctly, but then when saving
with the Editor save command, the command changes are not actually
saved, but the old value is?
I am really puzzled by this one, can anyone help?
thank you

That makes it sound like the model isn't really changed to the value you
are expecting. When debugging, can you actually see the new value has
been set properly?

Is the item provider's notifyChanged method calling fireNotifyChanged
for the notification it's getting?

I'm doubting that the value has been set the way you expect.

That's basically not possible unless the value wasn't set at all or was
set again as a result of something else. Setting a breakpoint in the
setter method should help track what's actually being set...

Hi Ed,
I came to the same conclusion, that whatever I was doing was not on the
correct resource, so took a step back and realized both editors were
using a different Resource for the same URI, resulting the effects I
described.
sorry to have bothered you with this, now I crawl back under my rock 8-(
