Interactive clipping NullReferenceException
Call interactive clipping with no layer loaded
add "test" in output
NullReferenceException was unhandled by user code
This tool causes also crashes with
but as it works wiht other files, I think that this file is really the problem, because it gets geometry errors.
I can confirm the exception no longer appears because of the added checks in the tool form.
The GEOS part continues in so I close this issue.
A fix is committed for not allowing empty input to pass validation.
As for the particular shapefile it has problems indeed. It's can be processed now (likely because of my fix early today) but clipping produces no results, because clipping operation creates shapefile without Z value while GEOS dutifully preserves the value, hence type mismatch. I guess the right way to fix it would be to create Z shapefile (for some reason I explicitly hasn't done that before. Will fix later.
I can reproduce this error.
