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
PropertyModel<Boolean>(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
