Re: Custom Pagination
Hi,
your markup didn't make it - do you have wicket:id=navigator in it?

Re: Custom Pagination
Hi, your markup has wicket:id=navigator, but I don't see this id in your Java code.

Re: Model data lost when calling target.add before onSubmit
Hi,
The browser doesn't send any data for form elements which are not visible.
When clicking the AjaxLink you make panel1 invisible (display:none). The
following form submit submits only the visible form elements, thus empty
value is set to the checkbox's model.

Hi,
I have two panels added to a form. The idea is to create a step 1, step 2
type functionality where after clicking next on panel 1, it hides and shows
Panel 2.
I have a checkbox on Panel 1
add(new CheckBox(single, new
PropertyModel(SelectionPanel.this, single)));
and I have the following link
add(new AjaxLink(next) {
@Override
public void onClick(AjaxRequestTarget target) {
panel1.add(new AttributeModifier(style,
new ModelString(display:none)));
target.add(panel1);
JQueryEffectBehavior effectBehavior = new
JQueryEffectBehavior(#panel2, slide, slideOptions, 400);
target.appendJavaScript(effectBehavior.toString());
target.add(panel2);
}
});
I submit the form using AjaxButton on panel2 where I log out the
PropertyModel data. The data shows the defaults for single in panel1 but is
fine for any data in Panel2
I have narrowed it down to when I call target.add(panel1) in the onClick.
Does this call clear any Model data that has not been submitted?
Regards
Vishal

Re: how to handle null pointer exception while submit button
#setConvertEmptyInputStringToNull(false) could help, but with a stacktrace we can give you a better advice.
