Exception when querying Parent's Unowned field - key of parameter value does not have a parent #272

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Run attached test named testUnownedQuery() (jdoconfig.xml is attached)
2. Note exception (below)

What is the expected output? What do you see instead?
Query should return 1 object; Instead, an exception is thrown as the 
UnownedField does NOT in fact have a parent by design (it's unowned).

What version of the product are you using? On what operating system?
Latest snapshot compiled on my machine. Win 7.

Please provide any additional information below.
