[mapguide-users] SV: Runtime map problem

In that case, you will do something different.
You need to setup the layer to display all points correctly.
Use Studio or Maestro to accomplish this.
When the user needs to view the layer, you do this:
1. Get a copy of the LayerDefinition
2. Modify the "FILTER" property of the LayerDefinition to display only
the required data, eg: "ID > 500 AND ID < 510".
3. Save the copy in the session repository under a random name.
4. Get the runtime map, and either
5a. Replace the resourceId of an existing layer with the one from step 3, or
5b. Insert a new layer into the runtime map, pointing to the temporary
layerdefinition from step 3
6. Make sure the layer from step 5 is visible
7. Save the modified runtime map
8. Refresh the client.
If your map already contains the layer to be show, choose 5a, otherwise
choose 5b.
