[mapguide-users] Change Resource map in layout definition

[euskalmap]

Hi jackie,

I have display the <Map><ResourceId> tag before and after the modify and all
is correct : the modify is OK.
I thinks, perhaps i call my code not in the good instruction in mapguide
file : my code is called before the catchinstruction in the
/mapviewernet/mapframe.aspx


Thanks



Perhaps, the XmlDocument stripped out some attributes in the root element
when converting back to raw xml string content.
