[mapguide-users] Re: SetVisible worked in 2.0, fails in 2.1

[Tom Chadwin]

Confirmed that SetVisible(True) is the issue. This is the code:

MgInitializeWebTier ($configFilePath);
$userInfo = new MgUserInformation($mgSessionId);
$siteConnection = new MgSiteConnection();
$siteConnection->Open($userInfo);
$map = new MgMap($siteConnection);
$map->Open($mapName);

//Create a filter to select the desired features.
$queryOptions = new MgFeatureQueryOptions();
$filterQuery = $_GET['searchColumn'] . " LIKE '%" . $_GET['searchValue'] .
"%'";
$queryOptions->SetFilter($filterQuery);

// Select the features.
$layer = $map->GetLayers()->GetItem($_GET['layerName']);
$featureReader = $layer->SelectFeatures($queryOptions);	

//display the layer
$layer->SetVisible(True);
$map->Save();

The stack trace gives:

- MgLayerBase.SetVisible() line 181 file
c:\osgeo\mapguide_21\mgdev\common\platformbase\MapLayer/LayerBase.cpp 

If I comment out the SetVisible(True) line, the rest of the script throws no
exceptions, and I get some data back.

Can anyone help?

Thanks

Tom
