      Description

      Dear All,

      I have an Imagemosaic Layer with 4 Bands with RGB band-combination 3,2,1. I have an SLD style (name=truecolor) set up with <ChannelSelection><Red/Blue/GreenChannel>.

      This Layer is displayed correctly when opening the WMS link, but when its within a Layer Group, the Band combination set in the SLD is not used, instead its the same output as using "style=raster", which makes an RGBA out of it.

      Of course I set the style in the Layer Group correctly.

      The log says:
      Styles = [StyleImpl[ name=truecolor], StyleImpl[ name=raster_scale_dependent]]

      There is no Error message.

      The SLD style (name=truecolor):

       <?xml version="1.0" encoding="UTF-8"?>
<StyledLayerDescriptor xmlns="http://www.opengis.net/sld" xmlns:ogc="http://www.opengis.net/ogc" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/sld

    <UserStyle>
      <FeatureTypeStyle>    
        <Rule>
          <Name>Raster RGB</Name>
          <MaxScaleDenominator>1E06</MaxScaleDenominator>
          <RasterSymbolizer>            
            <Opacity>1.0</Opacity>
            <ChannelSelection>
              <RedChannel>
                <SourceChannelName>3</SourceChannelName>
              </RedChannel>
              <GreenChannel>
                <SourceChannelName>2</SourceChannelName>
              </GreenChannel>
              <BlueChannel>
                <SourceChannelName>1</SourceChannelName>
              </BlueChannel>
            </ChannelSelection>
          </RasterSymbolizer>
        </Rule>
      </FeatureTypeStyle>
    </UserStyle>
  </NamedLayer>
</StyledLayerDescriptor>

      Steps to reproduce (via Interface):

      1. Add the quicklook file as GeoTiff Store and Publish with style=raster.
      2. Put the fullres file into a folder and add the folder as Imagemosaic, publish with the style from above.
      3. Create a LayerGroup and add these 2 Layers.
      4. Preview Layers individually * => works as expected.
      5. Preview LayerGroup * => Channel Selection from SLD for the Imagemosaic is not working, showing the Layer as RGBA.

      • fullres layer is shown only at scale < 1.000.000

      All Settings left default.
      Tested on blank GeoServer 2.11.0
