hi all
        In order to display a form in the task pane i've the following code
in "....../mapviewerphp/window.php"

<body>
<script language="javascript">
{
function getsession()
{
sessionId=parent.parent.mapframe.GetSessionId();
}
function getmapname()
{
mapname=parent.parent.mapframe.GetMapName();
}
</script>


<form action="selectlocation.php" method="get">
Enter PanId <input type="text" name="PanId"/><br><br>

<input type="hidden"name="SESSION" value="javascript:getsession()"/ >
<input type="hidden"name="MAPNAME" value="javascript:getmapname()"/  >
<input type="submit" value="Submit" />
</form>

*and in the selectlocation .php i am having
*
 </head>
  <?php $ID= $_GET['PanId'];
    ?>.<br />

  <body class="AppFrame" onLoad="OnPageLoad()">

    <h1 class="AppHeading">Select features</h1>


    <?php
    include '../common/common.php';

    $args = ($_SERVER['REQUEST_METHOD'] == "POST")? $_POST: $_GET;
    $sessionId = $args['SESSION'];
    $mapName = $args['MAPNAME'];

    try
    {

      // Initialize the Web Extensions and connect to the Server using
      // the Web Extensions session identifier stored in PHP session state.

      MgInitializeWebTier ($webconfigFilePath);

      $userInfo = new MgUserInformation($sessionId);
      $siteConnection = new MgSiteConnection();
      $siteConnection->Open($userInfo);

      $map = new MgMap($siteConnection);
      $map->Open($mapName);

      // Get the geometry for the boundaries of District 1

      $districtQuery = new MgFeatureQueryOptions();
      $districtQuery->SetFilter("pan_id==$ID");

      $layer = $map->GetLayers()->GetItem('Panchayat');
      $featureReader = $layer->SelectFeatures($districtQuery);
      $featureReader->ReadNext();
      $districtGeometryData = $featureReader->
      GetGeometry('Data');

      // Convert the AGF binary data to MgGeometry.

      $agfReaderWriter = new MgAgfReaderWriter();
      $districtGeometry = $agfReaderWriter->Read($districtGeometryData);

      // Create a filter to select the desired features. Combine
      // a basic filter and a spatial filter.

      $queryOptions = new MgFeatureQueryOptions();

      $queryOptions->SetSpatialFilter('SHPGEOM', $districtGeometry,
MgFeatureSpatialOperations::Inside);

      // Get the features from the feature source,
      // turn it into a selection, then save the selection as XML.

      $layer = $map->GetLayers()->GetItem(0);
      $featureReader = $layer->SelectFeatures($queryOptions);

      $layer = $map->GetLayers()->GetItem(0);
      $selection = new MgSelection($map);
      $selection->AddFeatures($layer, $featureReader, 0);
      $selectionXml = $selection->ToXml();


    }
    catch (MgException $e)
    {
      echo $e->GetMessage();
      echo $e->GetDetails();
    }
    ?>

  </body>

  <script language="javascript">


    function OnPageLoad()
    {
      selectionXml = '<?php echo $selectionXml; ?>';
      parent.parent.SetSelectionXML(selectionXml);
    }

  </script>

</body>
</html>



*This code..But when i enter the panId in the form this error is occuring *

  Invalid argument(s): [1] = "javascript:getsession()" The session ID is
invalid because the session separator character was not found.Invalid
argument(s): [1] = "javascript:getsession()" The session ID is invalid
because the session separator character was not found. Exception occurred in
method MgUserInformation.SetMgSessionId at line 183 in file
d:\buildforgeprojects\mapguide_open_source_v2.0\build_27.16\mgdev\common\mapguidecommon\System/UserInformation.cpp


Any mistake in my coding?????
