How to place form in own public class for extending
I am trying to move a form from an inner class that extends Form to a public
class. This is so that I can override the onSubmit() method of my form.
Below are my files.
When I add the form to a wicket page with
add(new TemplateEditForm(templateeditform, templatemodel));
and the corresponding html code
form wicket:id=templateeditformeditform/form
My wicket code doesn't pick the wicket:ids in the TemplateEditForm.html file
up
WicketMessage: The component(s) below failed to render. A common

Re: How to place form in own public class for extending
I usually make a panel, add the form to the panel and write up the form in
the panel's markup.

Re: How to place form in own public class for extending
But how do you then extend the form in the panel and more importantly, how
do you override the onSubmit() method of that form?

Re: How to place form in own public class for extending
What if you want to reuse the inner class form in another page (you have to
make it public and non-inner for visibility) and then you want to override
the onSubmit() method. If I just create a public class MyForm and stick the
form contents (minus the form tags) in MyForm.html, then wicket cannot
find any wicket variables on the form (see first post).
If you encapsulate the form in a panel, then the only problem is that you
cannot get to the onSubmit() method of the form (but if you delegate all the
work to a public method on the panel, then you can override that). Not so
pretty.
This is a bit of a corner case, but the fact is that forms are not readily
accessible wicket objects like panels and pages ( you cannot easily extend
your own publically accessible forms) or am I missing something?

yes, what if what if. notice i replied to your original email, in
which you make no mention of reusability.
If you encapsulate the form in a panel, then the only problem is that you
cannot get to the onSubmit() method of the form (but if you delegate all the
work to a public method on the panel, then you can override that). Not so
pretty.
so something like this is horrible right:
class myform extends panel {
protected void onsubmit() {}
public myform(string id) {
super(id);
add(new form(form) { onsubmit() { myform.this.onsubmit(); }});
}
}
yes, it looks horrific.
This is a bit of a corner case, but the fact is that forms are not readily
accessible wicket objects like panels and pages ( you cannot easily extend
your own publically accessible forms) or am I missing something?
in wicket there are two kinds of components: ones that provide their
own markup and ones that do not. the core team feels that we have
covered all the core usecases with pages, panels, fragments, and
formcomponentpanels.
your usecase can be handled by selecting the reusability unit to be a
formcomponentpanel which contains the innards of your form rather then
the form itself.
that said, you can easily implement a form variant which provides its
own markup. see FormComponentPanel for clues.
