Jean-Baptiste Quenot commented on WICKET-313:
---------------------------------------------
Igor: yes ajaxrequesttarget.respond() can sometimes process user-provided code.
For example, the onAttach() method of my ajax-rendered RefreshingView
components call populateItem(), and this user method can possibly fail. So if
you don't object, I would like to remove try/catch in
ajaxrequesttarget.respond().

>
> Now the respond method of the AjaxRequestTarget is catching all the
> RuntimeExceptions that are throwed. I would prefer to handle this exceptions
> by myself. I have a requestTarget that is a wrapper of the wicket
> AjaxRequestTarget where we could made something in case of errors in the
> respond method of the AjaxRequestTarget.
> I'm using the AjaxRequestTarget to replace a wizard panel, in case of error,
> I would display an errors panel instance of the original panel.
