First project using EM and single table inheritance, I've got an
abstract base entity, with three concrete sub types, I'm putting a
qualifier in the Basic Tab's Qualifier field in the form of
(summaryRangeType="hour"), etc for each of the three types, obviously
with different values for each. The column used for differentiating
the types, "summaryRangeType" is a class property. There are some
reflexive relationships between the the three sub types, which are
always used, but not constrained as mandatory. Fetches to one are
resulting in generated sql to all three types, as if I'm fetching on
the abstract parent, which I'm not. What am I forgetting or not doing
correctly in EM? Thanks.
Bill
