Re: [udig-devel] How to pick up Coverage from Layer

["Jan Jezek" <h.jezek@xxxxxxxxxx>]

Hi Jesse,

Thanks for showing me the bearing. The AbstractRasterGeoResource probably should 
resolve GridCoverageReader but it seems to me that it is missing in the code. When I added
the 'adaptee.isAssignableFrom(GridCoverageReader.class)' statement in the
AbstractRasterGeoResource canResolve method (line 206) everything works fine.

Is this proper solution of a bug or am I still missing something?

Cheers,
Jan
