I'm not sure. Something sounds wrong. How does the work when not using ajax?
I mean, are you sure you are hitting problems related to dynamic behavior or
more with dealing with normal api semantics?
The debug should explicitly show you the content it is updating a component
with. If it has debug statements showing the content then it could be your
listener method doing something funky.
Mark Reynolds has become my favorite bug reporter of all time. His issues
usually come with completely self contained projects that I can invoke "mvn
jetty:run" on to see all the gory bug details (documented examples and all)
for myself. One such issue was unrelated to what you are experiencing but
does include a good example of doing exactly what you are trying to do.
Perhaps it will be of some help.
http://issues.apache.org/jira/browse/TAPESTRY-1072
Let me know if the documentation hasn't made something clear after you try
it out and I can attempt updating with whatever relevant information there
is.

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.
