No behavior listener found
Hi!
What does this error mean?
No behavior listener found with behaviorId 0
What is being done wrong? Normally, the site works ok but the error
log shows this kind of error.
Am I manifesting some known Wicket antipattern which causes this
error? Or is it just a result of another illegal state?

Hi Martin
I got them a lot when creating the wicket reaction game.. For me the
problem where that I added new components all the time and if in the
mean time the component disappared (we are talking miliseconds) and the
user managed to click the cells then they would get the problem..

Bad example, because AttributeAppender isn't temporary, but I've
written one for requesting the focus onload and that had to be
temporary.

Re: No behavior listener found
Posted by James Carman <ja...@carmanconsulting.com>.
A temporary behavior returns true from isTemporary(). Some behaviors
don't need to be remembered on the server-side (like
AttributeAppender, for example).

Re: No behavior listener found

The behavior might actually by a button's ajax submit.
The npe occurs finally at the setModelObject:

Re: No behavior listener found
Posted by Igor Vaynberg <ig...@gmail.com>.
the error means that a behavior constructed the url, but when the user
followed the url the behavior could no longer be found.
what npe? can you show the full stack trace?

Re: No behavior listener found
Posted by Martin Makundi <ma...@koodaripalvelut.com>.
What is a temporary behavior?
I do not understand conceptually how a behavior can be invoked if it
is no longer there..
The error log shows a nearby nullpointer exception which might have
occurred during the same OnAjaxChangeBehavior .. maybe it led into an
illegal state:

looks like the behavior that generated the callbakc url being invoked
is no longer there...
do you have any temporary behaviors on that component?
