jQuery Grid Plugin - jqGrid

Hi

I am trying to implement the tabbing functionality using the struts2 jquery plugin.

As per the struts2-jquery-showcase 1.8.1, I have simpe a jsp page which has code like so to call 3 seperate jsp pages which should all execute an action to load a grid:

   <s:url id="remoteurl1" action="goToDocumentDistGridAction" namespace="/setup"/>

   <s:url id="remoteurl2" action="goToDocumentTypeGridAction" namespace="/setup"/>

   <s:url id="remoteurl3" action="goToDocumentStatusGridAction" namespace="/setup"/>

    <sj:tabbedpanel id="remotetabs" spinner="Please wait ...">
      <sj:tab id="tab1" href="%{remoteurl1}" label="Remote Tab One" />
      <sj:tab id="tab2" href="%{remoteurl2}" label="Remote Tab Two"/>
      <sj:tab id="tab3" href="%{remoteurl3}" label="Remote Tab Three" />
    </sj:tabbedpanel> 

The problem is that only the 1st tab will load the jsp containing the grid information. When i click on the 2nd or 3rd tab, the jsp is partially loaded(as in the header text value <h2> shows on the page), however the code after that on the jsp page doesnt execute :

<s:url id="remoteurl" action="jsontable"/>

<s:url id="editurl" action="editjsontable"/>

When I debug the jsp page, I just seem to step over it in debug mode withouth the action classes execute() being called!

 <sj:grid> tag to display the grid does not execute the remoteurl and thus the grid doesnt display!

If I call the actions individually and withouth any tab, they all work perfectly well!!

Does anyone know is there anything different I need to set to ensure that remote tabs which show up grids work? Would appreicate your help on this matter.

My struts actions are:

//action below gets called by the tab to take me to my jsp page

   <action name="goToDocumentTypeGridAction" class="documentTypeTableAction" method="goToGrid">
        <result name="success">documentTypeGrid.jsp</result>
  </action>
        

//as the jsp page loads up, this action should be executed to load the grid. its executed only when its the 1st tab & not 2nd

//or 3rd tabs!!
    <action name="jsontable" class="documentTypeTableAction">
      <result type="json" name="success">
     </result>
    </action>

        <action name="editjsontable" class="documentTypeTableAction" method="edit">
      <result type="json" name="success">
     </result>
    </action>

Thanks in advance!
