Thank you for the isTemporary() suggestion.. . BTW before i got your reply i
tried implementing following way, by extending AbstractBehavior , not sure
if this is a good way..
@Override
public void onRendered(Component component) {
IRequestTarget reqTarget = RequestCycle.get()
.getRequestTarget();
if (reqTarget!=null && reqTarget instanceof AjaxRequestTarget) {
AjaxRequestTarget ajaxTarget = (AjaxRequestTarget)
RequestCycle
.get().getRequestTarget();
if (ajaxTarget != null) {
ajaxTarget.appendJavascript("new Effect.Fade($('"
+ component.getMarkupId() + "'));");
}
}
}
Is it possible to have a chaining behaviour class in wicket which is not a
request listener??
