[mapguide-users] Selection Issue (FeatureReader only grabbing 20 items)

[nclayton]

Hi all,
This has just recently become a problem. I am passing the selection xml to a
page to display parcel owner data. For an example, I select 256 parcels on
the map. The selection xml comes over fine, with all 256 parcels listed.
When I use a featureReader to get the parcel numbers from the features, It
only get the first 20.

Is this a setting I may have altered unintentionally, or could there be more
to it?

Here is the code that I am using to pull the information out from the
selection xml:
========================================================================
function GetObjKeys($sessId,$mapName,$sel){
  $obj_keys = '';
    if($sel != ''){
      InitializeWebTier();
      $userInfo = new MgUserInformation($sessId);
      $siteConnection = new MgSiteConnection();
      $siteConnection->Open($userInfo);
      $resourceService =
$siteConnection->CreateService(MgServiceType::ResourceService);
      $featureService =
$siteConnection->CreateService(MgServiceType::FeatureService);	
      $map = new MgMap($siteConnection);
      $map->Open($resourceService,$mapName);		
      $selection = new MgSelection($map,$sel);
      if($selection != ''){
        $layers = $selection->GetLayers();
        if(!$layers){ $layers = $map->GetLayers(); }
      }else{ $layers = 0; }
      $layer = null;
      if($layers){
      for($i = 0; $i < $layers->GetCount(); $i++){
        if($layers->GetItem($i)->GetName() == "parcels"){ $layer =
$layers->GetItem($i); }
      }
      $queryOptions = new MgFeatureQueryOptions();
      if($layer){
        $layerClassName = $layer->GetFeatureClassName();
        if($sel != ''){ $selString =
$selection->GenerateFilter($layer,$layerClassName); }
        $layerFeatureId = $layer->GetFeatureSourceId();
        $layerFeatureResource = new MgResourceIdentifier($layerFeatureId);
        $layerId = $layer->GetObjectId();
        $queryOptions->SetFilter($selString);
        $featureReader =
$featureService->SelectFeatures($layerFeatureResource,$layerClassName,$queryOptions);				
        $selTmp = '';
        for($pdx=0; $pdx<$featureReader->GetPropertyCount(); $pdx++){
          $pnm = $featureReader->GetPropertyName($pdx);
          if($pnm == 'PARCEL_ID_'){ break; }
          if($pnm == 'PARCELID'){ break; }
          if($pnm == 'Key'){ break; }
          $pnm = "";
        }
        if($pnm != ""){
          while($featureReader->ReadNext()){
            $stg = $featureReader->GetString($pnm);
            if($stg != ""){	$obj_keys .= "'" . $stg . "'"; }
          }
        }
        $obj_keys = str_replace("''","','",$obj_keys);
      }
    }	
    return $obj_keys;
  }else{ return ''; }
}
