[gdal-dev] 1.11 OGR_F_SetFieldDouble() then OGR_F_GetFieldAsDouble() always returns zero

[Nik]

Hey, thanks for this advice Even.  I think I may have actually stumbled on a similar issue in the past (with setting geometry) so I really should have known better.  

Thanks for the reminder.   Yes, an update to the doco would help newbies as well as people like me who only dabble around the edges.   

Cheers,
Nik.
