I am using hibernate to do collection filtering directly on my model objects. I have come across two bugs in doing so:
1) TRUE keyword incorrectly being considered a field name
2) indirect attributes not resolved to the correct field name when outer-join="true"
The generated WHERE clause
Code:
(client.active=projects0_.TRUE)
should read
Code:
(client1_.active=TRUE)
in the SQL shown below.
