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

[Hidekazu Shimaji]

Hello,

You also have to use the SetResource function with the MapDefinition, which you are going to
change, to the Library Repository.  The MapDefinition is a template for a run-time map, so
you have to change it to use permanently.

Recently we discussed a similar topic.  Please see the following link:

Regards,
