[mapguide-users] Resource data was not found

[Robert Bray]

This problem is not related to session timeout. MgMap.Open takes the 
name of the runtime map object, not a MapDefinition. Is this script 
invoked by an InvokeURL command? If so you should be getting the MAPNAME 
and SESSION parameters from the post data. The MAPNAME parameter should 
be passed into MgMap.Open as the second argument. The SESSION parameter 
should be used in the creation of MgUserInformation.

If you are not running this script from InvokeURL, then you need to call 
MgMap.Create instead, passing in an instance of MgResourceService, the 
resource id of the Map Definition, and name of the runtime instance of 
the map to create. There is no way to hook up a map created in this way 
back to the viewer however (or at least no way that I am aware of).
