[udig-devel] CRS not recognized in customized dataStore

[Theodor Foerster]

Thanks, the error message is gone. I set the IGeoResourceInfo.getCRS()
to the CRS of the supplied FeatureType, that works now well, if the
FeatureType CRS is the same as the CRS of the map, but if the map CRS is
different, I do not see any data (somewhat it seems to be plotted
outside the map). IGeoResourceInfo.getBounds() returns always the CRS,
which describes the extent of the features in its origin CRS.

So one of the two parameters, should be dynamic, but which one?
