Hi Francisco
It did.. You could try the isTemporary (return true) on the behavior, it
could mean that it will only add the behavior for that request, but I am
not sure.. Or you could try creating a new markupcontainer
(listOfCommentsContainer), it'll give it a new id..
Or you could stuff in some logic as a ajaxcalldecorator on your link,
that will clean it up in pure js...
I had some difficulties with exactly this when I did the wicket reaction
game.
I hope this helpes..

hmmm... wicket's ordinary ajax replace method?
the basic problem here is:
-when the page is first rendered, the following is added to the dom
(it's the behaviour responsible for this):
$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); })
-when i click on the "trigger" link (numberOfCommentsLink24) i fire an
ajax request, and add a webmarkupcontainer (listOfCommentsContainer25)
i want to "refresh":
target.addComponent(listOfCommentsContainer);
-the ajax response is: *not only* the updated
listOfCommentsContainer25, but *also* an <evaluate> section in the
ajax response, that includes:
$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); })
(of course, because the behaviour has been added to the
listOfCommentsContainer).
-... that means, i now have loaded in the dom *twice* :
$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); })
so with *one* click on the numberOfCommentsLink24 , i get *two* calls
to $('#listOfCommentsContainer25').slideToggle(450);
which basically slides up, and immediately down. that is, slide toggle
means it goes up (hides) if it was down (visible), it goes down
(shows) if it was up (hidden).
i want to avoid this behaviour by stopping the ajax response from
spitting back the javascript code for a second time. perhaps do
something inside the behaviour class?
hope it clarifies! thanks,
francisco

yes, i'm aware of those. but i'd want to 'remove' things from the
ajaxRequestTarget rather than append...
or, some way of attaching/executing behaviours only once?

theres a prepend / append js on ajaxRequestTarget, that should work...

hi,
we're using a home-grown wrapper for integrating jquery into wicket -
specifically for jquery effects.
and i'm having some trouble with ajax updates. i'll explain with an
example:
final WebMarkupContainer listOfCommentsContainer = new
WebMarkupContainer("listOfCommentsContainer");
listOfCommentsContainer.setOutputMarkupId(true);
add(listOfCommentsContainer);
AjaxLink<Void> numberOfCommentsLink = new
AjaxLink<Void>("numberOfCommentsLink") {
@Override
public void onClick(AjaxRequestTarget target) {
target.addComponent(listOfCommentsContainer);
}
};
listOfCommentsContainer.add(new JQueryEffectBehavior(new
SlideToggleEffect(), numberOfCommentsLink));
add(numberOfCommentsLink);
this code is basically outputting something like:
<script type="text/javascript" ><!--/*--><![CDATA[/*><!--*/
Wicket.Event.add(window, "domready", function() {
$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); }) ;});
/*-->]]>*/</script>
listOfCommentsContainer25 being the target container to slide,
numberOfCommentsLink24 the trigger.
this works fine per se. now when i click on numberOfCommentsLink24 ,
my list is refreshed (added it to the ajaxrequesttarget) and the
effect behaviour outputting javascript code again...
<ajax-response><header-contribution><![CDATA[<head
xmlns:wicket="http://wicket.apache.org";><script type="text/javascript"
src="resources/hub.app.wicket.components.jquery.JQueryResourceReference/jquery-1.2.6.js"></script>
<script type="text/javascript"
src="resources/hub.app.wicket.components.jquery.JQueryEffectCoreResourceReference/jquery-1.2.6.effects.core.js"></script>
</head>]]></header-contribution>
(...)
<evaluate><![CDATA[$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); })
]]></evaluate></ajax-response>
which means that i can visually perceive a very quick slideDown
followed by a slideUp (this is the normal slideToggle functionality).
is there a way not to include the <evaluate> part? or detect if the
component has already been rendered in markup to check whether to
execute the behaviour again?
perhaps i'm missing some basic point here... any suggestions?
thanks in advance,
francisco
