The code looks alright.
Do you refresh the map afterwards?
What is in the "insertResults" ?
(There can be a hidden error, due to a bug in MapGuide)
Are you sure that the LayerDefinition matches the FeatureSource?
Try to create the FeatureSource and LayerDefinition in "Library://" instead,
so you can examine the layer from Studio/Maestro.
