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 ;)

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!

Re: How to retrieve ListItem objects from a ListView
Not really sure if this is what you are trying to achieve but here it is anyway: public final List ListView#getModelObject() On Mon, Dec 13, 2010 at 8:19 PM, drf wrote: > > I have the following use case : > > Having built a page using a standard ListView and implementing > populateItem(), I then want to pass the ListView to a method, extract the > contents, and use those contents to build a spreadsheet, cvs file, etc. > This > way, there will be no need to repeat the same logic (i.e. the logic used in > populateItem()), in more than one place. > > What is the best way to extract this information?

Re: repeters with
Use RepeatingView#newChildId() in order to generate unique id for each of
your LinkAndImagePanels while iterating through these like this:
for (LinkAndImagePanel panel : allPanels) {
String id = repeater.newChildId();
repeater.add(new LinkAndImagePanel(id, entry));
}
