Exceptions
Hi,
Some of our users keep complaining about unexpected exceptions so I was
investigating what kind of exceptions occur. Now it seems it's quite
easy to get an exception if you double click on an 'OK' button. (Some
people still don't know where to single click or double click :-S)
org.apache.wicket.core.request.handler.ListenerInvocationNotAllowedExceptionBehavior

okButton]] Behavior:

The autocomplete works as expected so it doesn't trouble the user.
Anybody else getting this exception or does it depend on our configuration?

Re: Exceptions
Posted by Dan Haywood <da...@haywood-associates.co.uk>.
quick update, ISIS-1544 is now fixed and will be in 1.13.2. I've made the
double-click prevention the default, but added a viewer setting to disable
it in case it causes issues.
Thx
Dan

I'm sorry. I can't figure this out. May be it's gone with the next
Wicket upgrade. It's not really a problem because the user experience is
not influenced and it has no other impacts.
The other exception after a double click on an okButton is a problem
though. Should I raise a ticket for that?

Perhaps you could just throw and catch a stacktrace in both cases, logging
to stdout; then force the error and see what you get?

differently because the ajax request times out (I believe) and I get a
different exception.

It is up to the application to decide how to prevent double form
submittions.
An easy way is to disable the button during Ajax call, e.g.
Wicket-Bootstrap provides integration with Ladda

This is a bug, but I am not sure where exactly.
An application should not try to write both to the Servlet's writer and
