Bryan Pendleton updated DERBY-3002:
-----------------------------------
Attachment: withDagsCastTest.diff
Attached patch "withDagsCastTest.diff' includes the test suggested by Dag on
1-sep-2009. I don't understand why the CAST operator has this strange effect on
the code, so for the time being this test fails while I research the behavior.
