[Geoserver-devel] TRANSPARENT=true

Seems that there is an issue with TRANSPARENT=true. I'm using version 1.2.1 of geoserver, but TRANSPARENT=true doesn't work.
I corrected the source code that request.setTransparent is
set accordingly to TRANSPARENT=true|false

So this flag gets to JAIMapResponcse and is set correctely,
but the map isn't tansparent. Where is the problem.

Run into this problem, as I tried to put different layers
on top of each other. Have a look at:

But only top level is showing which is wrong.
Any suggestions?
