debug statement says it has updated the content of the component, but the
options are still the old ones.
I also ran the app on debug, and set a breakpoint within the
renderComponent() method in the PropertySelection class. It seems it still
grabs the old value of the model, even after I updated it.
I also tried with other bindings, such as "disabled", and it doesn't work
either. The only binding I can see updated is the "value" binding.
Also tried with a surrounding div, still no success.
Is there a chance this would work better with the Select/Option components?
Didn't try those (I never used them actually).
My app really needs to update the full content of a dropdown list depending
on some other selections. I used to achieve this with XTile components, and
that worked like a charm, but required quite a lot of javascript plumbing.

It should work, I ~think~...What kind of response do you get from the
server
? (via the dojo debug statements or FireBug ? )
