Re: Question regarding AjaxFormSubmitBehavior
Many thanks for your feedback!
I am well aware of the fact that HTML spec actually does not allow nested
forms and that wicket is already doing great job while transforming those
nested forms into divs.
I also expected that the bigger form gets submitted as well but only the
nested one processed and the rest ignored, but that's not exactly what's
happening in our case.
The reason for this is that AjaxFormSubmitBehavior always delegates to the
#onFormSubmitted() of the root form
AjaxFormSubmitBehavior, line 135:
getForm().getRootForm().onFormSubmitted();
which then looks up if there is any enabled, visible
IFormSubmittingComponent in the hierarchy that has been triggered. Only in
case that one such IFormSubmittingComponent gets identified, it sets
*formToProcess* to the form of the identified submittingComponent and then
finally invokes
Form, line 920: formToProcess.process(submittingComponent);
The problem with our crazy liitle nested form ;) is that it does not have
any IFormSubmittingComponent but rather a TextField with
AjaxFormSubmitBehavior attached to its "onchange" event that should then
submit the nested form accordingly. This leads to formToProcess being left
assigned to the parentForm that then gets processed at the end:
- from Form#onFormSubmitted():
// this is the root form
Form formToProcess = this;
// find out whether it was a nested form that was
submitted
if (submittingComponent != null)
{
formToProcess = submittingComponent.getForm();
}
// process the form for this request
formToProcess.process(submittingComponent);
We have in the meantime subclassed AjaxFormSubmitBehavior with our own
implementation of AjaxFormSubmitBehavior#onEvent(AjaxRequestTarget target)
method the only difference being the line 135 that was changed from
getForm().getRootForm().onFormSubmitted();
to
getForm().onFormSubmitted();
and did not experience any problems with it, at least so far ;)

Re: Question regarding AjaxFormSubmitBehavior
Adding to Igor's comment, remember that nested form is not allow in HTML
spec per se, so what wicket is doing a trick where the root form is submit
but only elements of nested form (which get transform in DIV tag) are
processed

Re: Question regarding AjaxFormSubmitBehavior
the bigger form needs to be processed because what is submitted is the
root form's formtag. however, validation, etc, will probably be
delegated only to the inner form.

Question regarding AjaxFormSubmitBehavior
Have a small question regarding using AjaxFormSubmitBehavoir with nested
forms.
Would like to use it to submit a smaller nested form within a bigger parent
form.
Even though I passed a nested form as a "*form that will be submitted*"
while calling the following constructor of AjaxFormSubmitBehavoir :
/**
* Construct.
*
* @param form
* * form that will be submitted*
* @param event
*javascript event this behavior is attached to, like
onclick
*/
public AjaxFormSubmitBehavior(Form form, String
event) <- passing nested form here
{
super(event);
__form = form;
if (form != null)
{
form.setOutputMarkupId(true);
}
}
I noticed that the AjaxFormSubmitBehavior#onEvent(AjaxRequestTarget target)
executes the following line first:
"getForm().getRootForm().onFormSubmitted();"
Why does it still delegate to the root form?
Shouldn't the line be "getForm().onFormSubmitted();" so that the nested form
and possibly its children get processed only.
Many thanks!
Daniel
