The first row is not visible in the attribute dialog box when editing if the geometry type is ESRI Spatial Type in Oracle and the first row contains a NULL geometry.
This is a known issue.
Use the INSERT command to insert a new feature. For example:
INSERT INTO waterpolys VALUES (st_polygon('polygon ((10000 520000,1
00008889 55000, 1045545983 234280934, 10000 520000))',9));
