Yes, that looks right.<br>
<br>
You must also refresh the map (refresh/pan/zoom/etc.) in the browser
via javascript.<br>
<br>
In addition to my other suggestions, you can also check the error log
for messages.<br>

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