[mapguide-users] can't update and delete from feature source but insert works

[mitcha]

hello everybody,

i need help!!!  i try tu update and delete a feature source (sdf file), but
it doesn't work! instead inserting new data into feature source work very
well! i searched for solutions in this forum and i found some similar
problems.

So I first tried to set the readonly flag of the schema to false with the
mapagent. now the xml presentation looks like this:

<FeatureSource xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
<Provider>OSGeo.SDF</Provider>
<Parameter>
<Name>File</Name>
<Value>%MG_DATA_FILE_PATH%userPoints2.sdf</Value>
</Parameter>
<Parameter>
<Name>ReadOnly</Name>
<Value>FALSE</Value>
</Parameter>
</FeatureSource>

But it doesn't work!!!

furthermore i tried to set the identity property to readonly="false" with
the help of Fdo2Fdo. But it doesn't work, too. i always get an error
message. Could this be my fault? can i change this value of the identity
property?

The last possible reason could be an error im my source code. so here it is:

    // --------------------------------------------------//
    // Basic initialization needs to be done every time.
	
    MgInitializeWebTier($webconfigFilePath);
    
    // Get the session information passed from the viewer.
    $sessionId = ($_SERVER['REQUEST_METHOD'] == "POST")?$_POST['SESSION']:
$_GET['SESSION'];
       
    // Get the user information using the session id,
    // and set up a connection to the site server.     
    $userInfo = new MgUserInformation($sessionId);
    $siteConnection = new MgSiteConnection();
    $siteConnection->Open($userInfo);
    
    // Get an instance of the required service(s).    
    $resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);
    $featureService =
$siteConnection->CreateService(MgServiceType::FeatureService);      
	$queryOptions = new MgFeatureQueryOptions();

    //---------------------------------------------------//
    // Open the map
    $map = new MgMap();
    $map->Open($resourceService, $mapName);
      
      // Create the feature source
	$featureSourceName =
'Library://einzelBaum/Daten/userPoints2.FeatureSource'; 
    $resourceIdentifier = new MgResourceIdentifier($featureSourceName);
	$layerClassName="points2";
	 
	//$selectionString=$key;
         $selectionString="KEY=1";// just for testing
	$queryOptions->SetFilter($selectionString);	
	
	$featureReader = $featureService->SelectFeatures($resourceIdentifier,
$layerClassName, $queryOptions);
	
	while ($featureReader->ReadNext())
	{
	  
	  $searchName = $featureReader->GetString('NAME');
	  echo 'searchName: '.$searchName;

	  $searchBeschreibung = $featureReader->GetString('Beschreibung');
	  echo 'beschrName: '.$searchBeschreibung;
	}
		 
	
	// We need to add some data to the sdf before using it.  The spatial
context
	// reader must have an extent.
	
	$propertyCollection = new MgPropertyCollection();
	
	$nameProperty = new MgStringProperty("NAME", $name);
	$propertyCollection->Add($nameProperty);

	$beschreibungProperty = new MgStringProperty("Beschreibung", $beschreib);
	$propertyCollection->Add($beschreibungProperty);
	
	$cmd = new MgUpdateFeatures("points2", $propertyCollection, $queryOptions); 
	
	$featureCommandCollection = new MgFeatureCommandCollection();
	$featureCommandCollection->Add($cmd);
	
	// Execute the "add" commands
	if ($featureCommandCollection->GetCount() >= 1 )
      { 
		echo "commands.GetCount: ".$featureCommandCollection->GetCount();
		$featureService->UpdateFeatures($resourceIdentifier,
$featureCommandCollection, false);    
	}
	
	$featureReader2 = $featureService->SelectFeatures($resourceIdentifier,
$layerClassName, $queryOptions);
	
	while ($featureReader2->ReadNext())
	{
	  
	  $searchName = $featureReader2->GetString('NAME');
	  echo 'searchNameAfter: '.$searchName;

	  $searchBeschreibung = $featureReader2->GetString('Beschreibung');
	  echo 'beschrNameAfter: '.$searchBeschreibung;
	}
	
    //---------------------------------------------------//
    //  Save the map back to the session repository
	
    $sessionIdName = "Session:$sessionId//$mapName.Map";
    $sessionResourceID = new MgResourceIdentifier($sessionIdName);
    $sessionResourceID->Validate();
    $map->Save($resourceService, $sessionResourceID);
    //---------------------------------------------------//   

i hope that anybody can help!

greetz mitcha
