We just moved back to version 2.2 because we have problems with the digitising of PostGIS-Layer with an integer foreign key. The foreign key has no "not null"-constraint. When we edit it and leave it empty the following message pops up:

Provider errors:
PostGIS error while changing attributes: ERROR: insert or update on table "layer" violates foreign key constraint "fk_layer_group"
DETAIL: Key (fk_layer_group=(0) is not present in table "layer_group".

I guess its a bug with the null values for the attributes.

- Which editor widget is configured for the field (vector layer properties /fields tab)?
- How are you editing the attribute? (Feature form, attribute table...)

Some similar bugs have recently been fixed, so this may already be solved in current master. It would be great if you could verify on the latest nightly releases if this is still an issue so it can be resolved for 2.6.

Ok - I tested it in the nightly build and its ok there.

In QGIS 2.4 I edited the feature in the attribute table and the feature form. I didn't configure any editor widget for that field - its just the default one.
