Ajax and async task
Hi,
I've got an AjaxButton and hidden panel with progress bar and status
message which is hidden in the beggining.
My idea is to display the panel when the button is clicked and span long
task.
This task would update a counter that the progress will display using
AjaxSelfUpdatingTimerBehavior.
The problem is that the task has to be run in separate thread so the ajax
completes
and panel is even displayed before task end.
Got the idea from
https://stackoverflow.com/questions/15337198/wicket-calling-a-lengthy-operation-and-updating-through-ajax
.
But I'm getting org.apache.wicket.WicketRuntimeException: There is no
application attached to current thread Thread-XX.
Any suggestions?
Thanks,
Zbynek

You can use Applucation.get('THE_NAME_OF_YOUR_APP') it works in other
threads as well

Hi Ernesto,
sorry I was away in the afternoon/evening.
Passing application into runnable constructor is working for me!

Works just fine for me here.
Seems this may be related to using Google Guice:
org.apache.wicket.WicketRuntimeException: There is no application attached
to current thread Thread-68
at org.apache.wicket.Application.get(Application.java:236)

Re: Ajax and async task
Posted by Zbynek Vavros <zb...@gmail.com>.
Yeah the difference (from what I see) is that ThreadPoolExecutor is used in
BgProcessApplication.
And usage of
https://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/Session.html#bind()
that is non-related.
None of that helps me...
@Maxim: Not sure what you mean but ThreadContext.getApplication() returns
my application
without the need to do anything
