Re: [Geotools-devel] Issue: GridCoverage layer from RenderingTransformation sporadically not displaying

[Martin D. <md...@op...>]

A bit more information on this:

- I'm 99% sure that the coverage is being generated correctly and passed to
the renderer, since I enabled the debug mode of the GridCoverageRenderer to
dump the coverage image to a file.
- I can't reproduce the problem in the context of a single query - it only
happens when a tiled map makes multiple requests at once.  I have control
flow enabled to allow only a single request at a time, but this doesn't
solve the problem.
