sideview Redirector from a chart

Hi.

I got a static select:

<module name="StaticSelect" layoutPanel="mainSearchControls">
            <param name="settingToCreate">group_setting2</param>
            <param name="label">Summarized by: </param>
            <param name="searchWhenChanged">True</param>
            <param name="staticFieldsToDisplay">
                <list><param name="label">Port</param><param name="value">Port</param></list>
                <list><param name="label">Host Storage Domain</param><param name="value">HSD</param></list>
                <list><param name="label">Logical Unit</param><param name="value">LU</param></list>
            </param>

After that I got an HiddenSearch:

<module name="HiddenSavedSearch" layoutPanel="panel_row1_col1" group="Title" autoRun="True">
    <param name="savedSearch">VSP_LU_Summary_IOPS_Top_TimeChart</param>
    <module name="ConvertToIntention">
         <param name="settingToConvert">group_setting2</param>
         <param name="intention">
             <param name="name">stringreplace</param>
             <param name="arg"><param name="summary"><param name="value">$target$</param></param> 
         </param>
         </param>                   
        ...
        <module name="HiddenChartFormatter">    
        ...

All this works well, I got a $summarize$ variable in my savedSearch. I want to add a redirector when an user click on the chart. I need to redirect to the correct view depending on the choice made by the user for $summarize$( LU or Host or HSD) and call the correct view $summarize$_Details.xml (LU_details, Host_Details.xml,HSD_Details.xml)

I tried this:

<module name="Redirector">
    <param name="url">$summary.label$_Details</param>
    <param name="arg.form.vsp">$vsp.label$</param>
    <param name="arg.form.$summary.label$">$click.value$</param>
</module>

But all variables are empty. Thanks for your help,
