 is the right way to let StalePageException be handled by wicket?

 Is there a problem if the page has PageParameters?

How to manage StalePageException

2015-02-18 Thread dpmihai 
Hi.

I have a WebPage which gives me a StalePageException when more requests are
made to it at the same time by same user's page, every one with a different
PageParameters object. I also have an AbstractRequestCycleListener with an
onException method in my application.

I read about StalePageException in this posts:
http://apache-wicket.1842946.n4.nabble.com/StalePageException-handling-issue-td4579247.html
and
http://apache-wicket.1842946.n4.nabble.com/Marker-interface-for-quot-internal-quot-exceptions-td4666099.html#a4666100

As I understand by default Wicket recreates the page when StalePageException
occurs.
It wont recreate the page only if you handle this exception yourself in
IRequestCycleListener#onException().

So my question is how to ignore StalePageException in my code?

 I tried:

public IRequestHandler onException(RequestCycle cycle, 
Exception e) {   

if (e instanceof StalePageException) {
return super.onException(cycle, e);
}

}

and even return null

But know it complains page parameters are not sent:

 Can't instantiate page using constructor 'public ...
(org.apache.wicket.request.mapper.parameter.PageParameters)' and argument
''.
