Ok. I am sorry to bother you. I add the behavior at before render time:
protected void onBeforeRender() {
super.onBeforeRender();
final Recorder recorder=palette.getRecorderComponent();
palette.getRecorderComponent().add(new AjaxFormComponentUpdatingBehavior(
"onchange") {
@SuppressWarnings("unchecked")
@Override
protected void onUpdate(AjaxRequestTarget target) {
....
}
});
}
and I has been working right to me. But, if you would like to extend Pallete
and overwrite newRecorderCompoent + adding the behavior, It seemed to be
fine.
