Getting intermittent ListenerInvocationNotAllowedException with
AjaxEventBehavior
I'm getting an intermittent ListenerInvocationNotAllowedException when using
an AjaxEventBehaviors.
(stacktrace below)
This is my code:
----------------------------
WebMarkupContainer con = new WebMarkupContainer( "container" ) {
@Override
protected void onConfigure() {
super.onConfigure();
setVisible( someFlag);
}
};
con.setOutputMarkupId( true );
con.setOutputMarkupPlaceholderTag( true );
con.add( new AjaxEventBehavior( "onmouseover" ) {
@Override
protected void onEvent(AjaxRequestTarget target) {
someFlag = true;
target.add( someLargerContainerComponent );
}
} );
---------------------
In the same panel, I have a second container with a second AjaxEventBehavior
attached. The code is the same as above, except that the behavior uses the
"onmouseout" event and the someFlag logic is reversed. The idea is that a
visible <div> is swapped out for another <div> on mouseover, and then the
swap is reversed on mouseout.
This works fine - except sometimes it doesn't. I would say the exception
occurs in about 1 out of 40 mouseovers/mouseouts. I can't discern a pattern.
I've tested this in FF and Chrome on Windows and the problem occurs in both
browsers.
I did read
https://issues.apache.org/jira/browse/WICKET-5603
which seems to suggest that this problem has been fixed - but I guess it
hasn't. I'm using Wicket 6.16.0.
(the workaround suggested in the jira comments doesn't apply to me since my
behaviors are not attached to form components)
Any suggestions on how to catch this exception or for another workaround?
Thanks!

Hi,
there might be other solutions too, but perhaps the child selector will
fit nicely:

Hmmm I tried to figure out how to do that but I don't get it.
I know to override updateAjaxAttributes() but I'm not sure how of the
meaning/function of the childSelector filter string. "The selector string
that filters the descendants" doesn't make too much sense, and I can't find
any other documentation. childSelector is not explained in the apache
wicket, either.
Would you mind elaborating?
Thank you!

Hi,
the request comes in when the component is already/again invisible on
the server.
Try adding the behavior higher up in the component hierarchy with
AjaxRequestAttributes#childSelector.
