[udig-devel] WMS Layer Z-Order

[markhamc.13526072@xxxxxxxxxxxxx]

Is anyone aware of the case where WMS layers get drawn with the wrong z-order?
This only happens when muliple WMS layers are placed adjacent to each other
(ie no non-WMS layers between). The problem is that the request to the server
has the layers in the opposite order of what they should be. 

I am using
MapServer, so it is possible that this is do to different interpretations
of the WMS specification. MapServer expects the layers to be specifed from
the bottom to the top, but the request from uDIG (or geotools) orders the
layers in the opposite direction (top to bottom).

For now it is simple
to work around the issue by rearranging the layers in uDIG, but it would be
nice to find the source of the problem.

Thanks,
Cole
