Re: FormComponent independent from the Model/Model object
Thanks to all! I used the Marios approach... The workaroud with another
Model worked perfectly. :)
@Richard: Everything is possible with javasript, but if wicket offers a
huge feature set, I see no need to use js...

You don't want an empty model either, just declare a class field and use a
PropertyModel instead.
Like so:
public class MyPanel {
// Add the field and its getter/setter (not shown here)
private boolean myCheckBoxState;
public MyPanel(id, IModelMyObj model){
super(id, new CompoundPropertyModelMyObj(model);
FormMyObj form = new Form(id, model);
// Specify a different model for your form fields that are
independent of MyObj
form.add(new AjaxCheckBox(anyStupidId, new
PropertyModelMyPanel(myCheckBoxState, MyPanel.this));
add(form);
}
}

Why don't you construct it with an empty model object, i.e., with new
Model()? Then the CPM from the panel is not accessed.

Re: FormComponent independent from the Model/Model object
Well, one approach is create it as a normal HTML control not render it
via Wicket. You can just attach a standard Javascript event (such as
onclick) to get the behavior you want.
Bottom line: You don't have to Wicketize everything on your page. Just
because you have a hammer, it doesn't mean everything is a nail.

Subject:FormComponent independent from the Model/Model object
Hi everyone,
I have a dummy question:
If I have a panel with a form (not everything is my code) -
public class MyPanel{
public MyPanel(id, IModelMyObj model){
super(id, new CompoundPropertyModelMyObj(model);
FormMyObj form = new Form(id, model);
form.add(new AjaxCheckBox(anyStupidId);
add(form);
}
}
And I want to add a Component (AjaxCheckBox) to the form above, but this
component shouldn't have anything to do with a model object. It's purpose
is just a change the state of the input fields. If I check the box the
field should be deactivated and vice versa. Nothing more.
My problem is, that Wicket thinks (and I even know why :)) the
anyStupidId is a field of MyObj and tries to change the value... Well,
the checkbox should be inside of the form, but I don't know if is it
possible to make this checkbox independent from the Model handling... How
can I tell wicket, hey dude, anyStupidId has nothing to do with MyObj, it
is really just a stupid id

Re: FormComponent independent from the Model/Model object
If you want to change the state of the input fields via javascript then do
what Richard said. I guess since you are using an AjaxCheckBox you want to
do it on the server side via ajax. So, here's what you need to do:
add a boolean property to the Panel (e.g. componentsEnabled) and bind
AjaxCheckBox to it: form.add(new AjaxCheckBox(anyStupidId, new
PropertyModelBoolean(this, componentsEnabled)).
Now whenever the checkbox is updated, the change is reflected to the
componentsEnabled property. You can use this property in the onConfigure
method of the panel or the individual components to alter their state:
e.g. form.add(new TextField(name) {
public void onConfigure() {
setEnabled(componentsEnabled);
}
});
To get the update working after the checkbox is clicked you need to handle
its onUpdate method and add the components whose change should change to
the ajax request target.
Hope this helps,
Marios
