I'm trying to add form components to a form using ajax. i've set
"setMarkupId(true);" on the form but when I run it, i get an error saying
"cannot update component that does not have setOutputMarkupId property set
to true. Component: [MarkupContainer [Component id = realTimeForm..."
So basically when someone moves 1 or more selections from the available to
the selected side of the palette, i want it to add another palette to the
form.
Code Snippet:
List valueList = new ArrayList(); // this actually has values
IChoiceRenderer renderer = new ChoiceRenderer();
Palette palette = new Palette("palette", new Model(new ArrayList()), new
Model(valueList), renderer, 5, false){
@Override
protected Recorder newRecorderComponent() {
Recorder rec = super.newRecorderComponent();
rec.setRequired(true);
rec.add(new AjaxFormComponentUpdatingBehavior("onchange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
Palette newPalette = new
Palette("newPalette",new Model(new ArrayList()),new Model(new
ArrayList()),renderer,5,false);
target.addComponent(newPalette);
}
});
return rec;
}
};
public Constructor(){
Form form = new Form("realTimeForm");
form.setOutputMarkupId(true); //enable ajax on the form
form.add(palette);
add(form);
}
