Workbench - qva.GetQvObject not working with specific ListBox

[#1]

Hi all

I am using Workbench with qlikview 10.

I have a webpage working, showing object from the qlikview document using code such as

<qww:QvObject  ID="QvObject6" runat="server" ObjectType="ListBox"  ObjectID = "LBXX06"

              QlikViewDocument="DocTest (Local)" Height="100px"

            QvAjaxZfcPath="http://JAP/QvAjaxZfc/" />

This works great. The object is shown. Therefore the qlikview document is working and workbench can access it.

I want to filter the list box using Javascript. I have used code like this, which works for other list boxes in other documents

<script type="text/javascript" language="javascript">

var SectorListBox;

     Init = function() {

       SectorListBox= qva.GetQvObject("LBXX06", function () {

              alert('here');

         });

    }

    Qva.BodyOnLoadFunctionNames.push("Init");  

     function Preset() {

       var values = ["=[Sector] = 'Motor' "];

       SectorListBox.QvaPublic.Data.SelectTexts(values);

     }

}

The problem occurs at this line:

  SectorListBox= qva.GetQvObject("LBXX06", function () {

              alert('here');

         });

I dont get the popup.

If I change LBXX06 to a different listbox in a different document, it works fine, i get the alert popup.

If i leave it as LBXX06 i get no popup

I have checked that LBXX06 exists in the document.

I have changed it to select a different object within the same document, and it works  update: no it doesnt sorry

So the problem seems to be with that specific list box on that specific document update: the whole document is affected

I cant find ANY documentation for issues such as this. Can you help??

Thanks!
