[mapguide-users] Adding layer to runtimemap

[Gunter Becker]

OK, initializing the RuntimeMapLayer works but after saving back the modified
map to the Session-Repository the MgServer service is terminated. I have to
restart the service and also the IIS.

When I debug my application I relize an error on the
RuntimeMapLayer.IDs-property:

     'runMapLayer.IDs' threw an exception of type 'System.Exception'
     Message: Cannot reload ID's because the layers parent is not set
     StackTrace: at
OSGeo.MapGuide.MaestroAPI.RuntimeClasses.RuntimeMapLayer.FindResourceIDs()
                      at
OSGeo.MapGuide.MaestroAPI.RuntimeClasses.RuntimeMapLayer.get_IDs()"	

So I've looked at the parent-property of the RuntimeMapLayer and it is set
to "null". Does this cause the problem? The parent-property is of type
MapDefinition and I'm wondering why I need a reference to the MapDefinition
at all?

What ist the best practice, when I want to add a new layer at runtime from
an exisiting MapDefinition in Library-Repository and which methode should I
use
