[Mapserver-users] SLD and multiple NamedLayer

[Yewondwossen Assefa]

Bart,

  I have tried to debug the problem this morning but was not successful. 
I can reproduce this on a windows machine but the the same setting works 
on a Linux setup. What is even worst was that on Windows, the request 
works when I am in the debugger.  I could not really pin point where was 
the problem but It seems that the inital parsing of the XML is the 
probelm (the XML seems to be valid but the parser returns an error).

  I have entered a bug on this for now in mapserver (bug 601).  I will 
give it another shot in few days.

Later,
