Re: Any indicator for Ajax-Rendering?
Yeah you're right... but i think i have to describe my problem i another way.
I have two linked DropDownBoxes and i want intially on Page-Rendering that
the second (child) drop downbox is filled by the initial value of the first
box.
the linking is done with my own "onChange" handler
protected void onChange(AjaxRequestTarget target, T newSelection){ };
the best would be, i could use this handler for initial rendering and
ajax-onChange, cause there i've implemented the processing of filling the
second drop down box By "newSelection"!
Thanks for any Hints!

Re: Any indicator for Ajax-Rendering?
Then it should come from an AJAX request as the code above shows...?? Ernesto On Tue, Apr 20, 2010 at 10:00 AM, MattyDE wrote: > > I know.

I know. But i breakpointed there... and AjaxRequestTarget.get() is not null in onBeforeRender -- View this message in context: http://n4.nabble.com/Any-indicator-for-Ajax-Rendering-tp2016955p2017047.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Any indicator for Ajax-Rendering?
That's really weird because the code of get is like
public static AjaxRequestTarget get()
{
final RequestCycle requestCycle = RequestCycle.get();
if (requestCycle != null)
{
if (requestCycle.getRequestTarget() instanceof
AjaxRequestTarget)
{
return (AjaxRequestTarget)requestCycle.getRequestTarget();
}
}
return null;
}
Best,
Ernesto

Re: Any indicator for Ajax-Rendering?
Not 100% sure but I think AjaxRequestTarget.get() will return null if request is not AJAX. Maybe you could use that as a "flag".

Any indicator for Ajax-Rendering?
Hi Folks, is there any indicator in onAfterRender() or onBeforeRender() inside a Component which tells me that this Component is now rendered (updated) through ajax (AjaxTarget.addComponent()), instead of the "normal" page-rendering? I need to know this, because i want to update an DropDownChoice by another DropDownChoice with "on change" handler. But if this second DropDownChoice has been updated, i want to update some other TextFields too... and the only "indicator" i have is, that the second DDC has been re-rendered Thanks for any Hints ;) -- View this message in context: http://n4.nabble.com/Any-indicator-for-Ajax-Rendering-tp2016955p2016955.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
