Ajax POST stopped because of precondition check

[Rik Overvelde]

Hello,

I've got a problem while integrating a JQuery Slider in a project that 
I'm working on. The basic idea is that when the value of the slider 
changes, a hidden textfield is changed as well and the value of this 
textfield is submitted using an AjaxFormComponentUpdatingBehavior. This 
is all working in Firefox, but in IE7 the ajax callback isn't fired.

When the slider is changed I see the following message in the Ajax Debug 
log: *: *INFO: Ajax POST stopped because of precondition check, 
url:?wicket:interface=:3:formulier:opslaanform:pagina:0:element:elementen:0:element:vraagPanelContent:indentContainer:invoer:sliderPanel:slidercontainer:slider:valueField::IActivePageBehaviorListener:0:-1&wicket:ignoreIfNotActive=true 


The following is the part of the generated HTML that takes care of this:

   <div aria-disabled="false" id="id2e" style="width: 785px;"
   class="center ui-slider ui-widget ui-widget-content ui-corner-all
   ui-slider-horizontal"><div style="left: 25%;"
   class="ui-slider-handle ui-state-default ui-corner-all"></div></div>
   <input id="id28"
   
name="pagina:0:element:elementen:0:element:vraagPanelContent:indentContainer:invoer:sliderPanel:slidercontainer:slider:valueField"
   value="1" onchange="var wcall=wicketSubmitFormById('id9',
   
'?wicket:interface=:3:formulier:opslaanform:pagina:0:element:elementen:0:element:vraagPanelContent:indentContainer:invoer:sliderPanel:slidercontainer:slider:valueField::IActivePageBehaviorListener:0:-1&amp;wicket:ignoreIfNotActive=true',
   null,null,null, function() {return
   Wicket.$$(this)&amp;&amp;Wicket.$$('id9')}.bind(this));;"
   type="hidden">       
   <script>$('#id2e').slider({min: 0, max: 4, change: function (e, ui)
   { document.getElementById('id28').value = ui.value; var ajaxCall =
   eval(document.getElementById('id28').onchange); ajaxCall(e);},
   steps: 4}).slider('enable');</script>


Does anyone have an idea about what is going wrong here?

Thanks in advance
