How to filter Blob field?

Post by legende » Mon 03 Dec 2012 08:27

Is it possible to filter not null blob fields?

I downloaded the latest version, added field BLOB with type ftBlob, and tried to filter by "BLOB IS NOT NULL" and "BLOB <> ''". Both cases give following error message "Cannot convert type 13"

For the time being, filter by BLOB fields is not supported, we will investigate the possibility to implement this functionality in one of the next versions.
