That should really work. I'm using something very similar (checkbox instead
of radiobutton). If you post some code, I can look for differences.


2007/6/27, Julian Wood <[EMAIL PROTECTED]>:

I have a pretty straight forward paradigm:

- two groups of 3 radio buttons followed by a property selection.
- an async form with no listener whatsoever
- a submit button with an action listener (called saveTime)

The idea is that choosing a radio button narrows down the list in the
property selection.

I chose to add eventlisteners to the onclicks of the radiobuttons,
and update the property selection in response. The eventlisteners
submit the above form, which is why there is no listener set in the
form binding. For simplicity, I'll call one eventListener method
categorySelected.

This form is entirely contained within a Dialog component, which is
reused.

Now, this all works perfectly the first time through - open the
dialog, fill out the form, watch the property selection values
change, submit the form, close the dialog, reset all the fields. Note
that saveTime is not called when you click a radio button - only
categorySelected.

The second time the dialog is opened, the eventlisteners behave
slightly differently. This time, when you click a radio button, the
form is submitted, categorySelected is invoked _and_ saveTime is
called (which is a problem). The primary difference between the two
posts (at the request level) is the inclusion of the name of said
button, which I believe is how Tapestry determines what listener to
call (ie if &addTimeEventButton=Save%20Time is included, then
saveTime is called - correct me if I'm wrong).

So I'm wondering why the eventlisteners call saveTime (some of the
time), if there is a way to prevent that, or if there is a better way
to approach this problem all together (is an async form with no
listener at all okay?). I know there are a bunch of workarounds, but
I'm looking for that clean solution.

Thanks,

J
