[mapguide-users] Storing WebLayout in Session Repository

[Hidekazu Shimaji]

Hello,

Not "NeulingenALK.Map" but "NeulingenALK.MapDefinition" is required for the WebLayout.
I tried the same way of you, but it did not work.
I don't know why.  I finally gave up using the MgMap class, 
and used the SetResource function for setting a xml of the MapDefinition.

Does anybody know about it?

Regards,
Hidekazu Shimaji
