Hi Andrea,

I think I found the issue.

This request works:
?FORMAT=image%2Fpng&TRANSPARENT=FALSE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&LAYERS=d&SRS=EPSG%3A25832&BBOX=281628.86785608,6110430.5035682,359900.3848201,6188702.0205323&WIDTH=256&HEIGHT=256&tiled=true&tilesOrigin=280000%2C5200000

And this doesn’t:
?FORMAT=image%2Fpng&TRANSPARENT=FALSE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&LAYERS=d&SRS=EPSG%3A25832&BBOX=281628.86785608,6110430.5035682,359900.3848201,6188702.0205323&WIDTH=256&HEIGHT=256

So geoserver throws the exception because of the following missing parameters:
&tiled=true&tilesOrigin=280000%2C5200000

As far as I understood those are vendor parameters and geoserver should return 
the image also without them. Is this correct?
Can you reproduce the problem?

Best,
Anna

Hi Anna,
the main issue here is making the problem reproducable.
For the past few months I've worked a lot of image mosaics and did not stumble 
into
this problem.
To make sure there is nothing particular about my settings I've downloaded the
latest nightly build and played with the build-in image mosaic with the 
following variations:

  *   layer preview vs GWC internal preview
  *   in the layer preview single tile and tiled mode
  *   nearest neighbor and bilinear interpolation
  *   wgs84 and web mercator
  *   completely outside the image, on the border between inside and outside, 
in a hole of the image
However none of these tests lead to a NullPointerException. So, it's now up to 
you: try to isolate
what is causing the NPE and when you have, share data and instruction to make 
it happen :-)

Cheers
Andrea

Hi Andrea,

we installed and tested the nighly build – the transformation error is gone, 
but the Nullpointer-Exception is still there.

Here is a picture with OpenLayers with the service running with the nightly 
build:

Currently I am running the service as ImageMosaic – same error…

Best,
Anna

Hi Andrea,

thanks for the reply!

I removed the footprints ( ;)! ) and it’s still the same problem. I also added 
a new layer with a ImageMosaic Datasource – pointing to 0-Folder in the 
pyramid. It’s still the same error – it only occurs if I am requesting a tile 
size.

We will install the master tomorrow and test if the problem is solved. The 
error message is quite different – plus we don’t have a color map in the sld 
and we can’t view the layer in any other CRS.

The color map is actually not part of the problem, it happens also with other 
raster types, the reporter
discovered it on that case and reported it as such.

Cheers
Andrea
