[mapguide-users] [ZS1] Drawing order of layers in a map

[m.karam]

thanks for your reply
I tried that ..
but sometimes, the features of the layer that i remove, don't appear unless
i refresh that layer from the legend


i tried another solution ..
to change the layers order in the map definition and save it in the session.
And also, update the web layout by changing the ResourceId of the map.
Now, I have a map definition and web layout in the session

but when i pass the new web layout to the viewer, it gives me an error
message:
"MgInvalidMapDefinitionException"

what will i do for this error?
Is that any error in the XML of the map definition?
please help ...
