Hi
I have a very simple sub query. when I try to execute this sub query I
get NPE . looking at stack trace it seems to come from query
expression parser. The JQL is
select stgrp from Stagegroup stgrp " +
" where stgrp.dumpId = :dumpId and stgrp.name " +
" IN ( select xname from group grp " +
" where grp.prop1 = :value1)
I have also looked at openJPA-16 and OpenJPA-157. I am not supplying
null values anywhere. is this some known issue , any further clues or
how I can go about making sure its a code bug and not openJPA or
vice-versa ?
openJPA version is => openjpa-1.0.1-r420667:592145
.
