[mapguide-users] Get selected layers from server side

[Jim O'Leary]

Yes, this works. The part that I was missing was:

selection.Open(resourceService, mapName);

When you do this, you give the selection object access to the session
through the resource service object. Then it knows the layers that the user
selected. Much cleaner than the JavaScript route.

Thanks.
