[mapguide-users] Error: Unable to Make Permanent Changes to Map

[Jim O'Leary]

Has there been an answer to this question? Can you save a runtime map to the
repository?

I have a map to which a user can add a new layer to a given layer group
using the browser. My program can save the new layer to the repository using
SetResource(), and can add it to the given layer group in the runtime map.
Is there a way to programmatically save the runtime map with the new layer
to the repository?

Thanks
