I just downloaded QGIS 2.2 to check it out and now one (just the one) of the tables from one of my PostgreSQL database won't display.
It loads just fine in 2.0. The records are all there (there's only 3 in this case), I can see them in the attribute table, I can query them, but they don't show up on the map.
When I try to zoom to a particular feature it pans the map down to the origin of the datum (coordinates 0,0) - but when I zoom to the extent of the layer it sets the map back to where it is supposed to be.
What am I missing in the jump from 2.0 to 2.2?
