Martin Grigorov closed WICKET-3179.
-----------------------------------

       Resolution: Not A Problem
    Fix Version/s: 1.5-M4
                   1.4.14

You can visit the children of the Form and add the behaviors:

Form form = new Form("formId") {

 protected void onConfigure() {
  super.onConfigure();

  visitChildren(FormComponent.class, new IVisitor<FormComponent>() {
	public Object component(FormComponent component) {

             // pseudo code
             if component has no mybehavior then
                  component.add(mybehavior);
             fi
             return CONTINUE_TRAVERSAL;
	}
});
}

>    Affects Versions: 1.4.13
>         Environment: Java 1.6, Windows.
>            Reporter: Jean-Francois Larouche
>            Priority: Minor

>   Original Estimate: 1h
>  Remaining Estimate: 1h

> Weve got a little problem and i dont know if theres another way to do this. Ive searched and found nothing.
> We need to add some sort of ErrorBehavior to all of our form components. And the code duplication starts to be very ugly.
> Would this be possible/make sense:
> When the components renders, they call getBehaviors();
> getBehaviors() could then not only get the Component one but also call
> Application.get().getDefaultComponentBehavior(); and return the merged list.
> This does not affect anything in current wicket implementation.
