New Revision: 7700

Modified:
   sandbox/adsk/2.4j/Web/src/HttpHandler/OgcWmsServer.cpp
   sandbox/adsk/2.4j/Web/src/HttpHandler/WmsMapUtil.cpp
Log:
#2323: WMS should not throw exception if no coordinate system set up
Fix the exception and create image without coordinate system transformation in this case.
