Francesco Degrassi updated TAPESTRY-1775:
-----------------------------------------
Attachment: form.js.diff
I had the same issue in the following scenario:
* form not updated asynchronously
* asynchronous direct link in the form that submits it and calls listener X
* synchronous search button in the form that calls listener Y
The problem was the following:
* clicked on the async direct link -> listener X called
* clicked on the sync button -> both listeners X and Y called
Using FireBug shows that the form submitName field was left set to "direct link
name" after async submit and following sync submit sent again the "stale"
submitName value.
I attached a patch that clears the subminName hidden field when appropriate
after a form submit
> Multiple submit buttons inside async form can invoke incorrect listener

> ... this can happen when the updateComponents of the buttons doesnt cover the
> form.
> So, in such a case, when button1 is clicked it sets itself as
> tapestry.forms.form['Form'].clickedButton
> and correctly does the async form submit.
> However, the xhr response does NOT include any calls to
> tapestry.form.registerForm since (as stated)
> updateComponents may not really include the whole form. So, what this means
> is that the old value for
> tapestry.forms.form['Form'].clickedButton remains - triggering the associated
> listener no matter how the
> new form is submitted.
