Background color of one WMS layer overwrites other WMS layer data when WMS layer group is made
----------------------------------------------------------------------------------------------

                 Key: GEOS-3197
                 URL: http://jira.codehaus.org/browse/GEOS-3197
             Project: GeoServer
          Issue Type: Bug
    Affects Versions: 1.7.5
         Environment: Windows XP & Linux
            Reporter: Ivan Grcic
            Assignee: Andrea Aime
         Attachments: 1.jpg, 2.jpg, Untitled-1.jpg

In v1.7.4 new option for ImageMosaic plugin is added: BackgroundValues which unable us to set color of the background where there is no data (images)

Although background color works fine now for single layer, when you combine mosaic layers in one WMS layers, the background color (areas where data doesnt exist) covers the other layer data

I attached screenshots (i changed the white bg color for gray, sou you can see where the extent of two mosaics are)

In 1.7.2 works normal, in 1.7.4&5 problem occurs.

Regards,
Ivan
