I had a similar experience this afternoon - I added a column, filled in values manually, clicked the save button, closed the attribute table, reopened it, and I think the values were all NULL (not 0). Could it be related?

Actually, I just had it happen after using the field calculator too. The values ended up as NULL.
Am I going crazy?
Do you remember why you decided your report was invalid?

Wrong field type maybe?

I've just heard a report from someone using QGIS 1.8 of the same problem as in my last comment - I'll open a new ticket if there isn't one already.
I don't believe this is an issue of the wrong field type. Can't that only be an issue if the field calculator puts text in a numerical field (in which case it changes to 0 when it is saved)?
