I may elaborate what is my setting ...

Firstly I renamed the fusion/index.html to index.php and put the following
code to the index.php

<?php
$layer =  $_GET['layer']; 
$objectid =  $_GET['objectid']; 
?>

and then created a file selectbyparameters.php to the folder /fusion/

&lt;!DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot;
&quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot;&gt;
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>load map</title>
</head>
<?php 
$layer =  $_GET['layer']; 
$objectid =  $_GET['objectid']; 
$sessionId = $_GET['SESSION']; 
$mapName = $_GET['MAPNAME']; 
$webconfigFilePath = "c:\\Program
Files\\Autodesk\\MapGuideEnterprise2010\\Server\\Bin\\serverconfig.ini"; 
MgInitializeWebTier ($webconfigFilePath); 
$userInfo = new MgUserInformation($sessionId); 
$siteConnection = new MgSiteConnection(); 
$siteConnection->Open($userInfo); 
$map = new MgMap($siteConnection); 
$map->Open($mapName); 
$selection = new MgSelection($map); 
$layer = $map->GetLayers()->GetItem($layerName); 
//Turn on Layer and GroupLayer if they're off 
$grouplayer = $layer->GetGroup(); 
$queryOptions = new MgFeatureQueryOptions(); 
if($layer->IsVisible() == false) 
{  $layer->setVisible(true); 
    $layer->ForceRefresh(); 
    $map->Save($resourceService); 
} 
if($grouplayer->IsVisible() == false) 
{  $grouplayer->setVisible(true); 
    $map->Save($resourceService); 
} 
$filter = "objectid = $objectid"; 
$queryOptions->SetFilter("$filter"); 
$featureReader = $layer->SelectFeatures($queryOptions); 
$selection->AddFeatures($layer, $featureReader, 0); 
$selectionXml = $selection->ToXml(); 
$featureReader->Close(); 
?> 

</body>
</html>

Finally I modified the ApplicationDefinition.xml to initial the
selectbyparameters.php

<Widget xsi:type="WidgetType">
      <Name>TaskPane</Name>
      <Type>TaskPane</Type>
      <StatusItem/>
      <Extension>                                                                                                       
        <MenuContainer>TaskContextMenu</MenuContainer>
        <InitialTask>selectbyparameters.php</InitialTask>
      </Extension>                                                                                                      
</Widget>    

Who can tell me? Is it correct? Thanks.
