Hi Lionel,
Thanks and yes, thats what I am trying to do, attach some javascript after
something has rendered. So I attached an AjaxEventBehaviour to it and now have
this:
add(new AjaxLazyLoadPanel("myPanel") {
@Override
public Component getLazyLoadComponent(String markupId) {
return new SomePanel(markupId);
}
}.add(new AjaxEventBehavior("onload"){
protected void onEvent(AjaxRequestTarget target){
target.appendJavascript("alert('hello)';");
}
}));
but the javascript is never fired.
Any more ideas?
cheers,
Steve
