Hi!
tks your help I use OJB in cocoon tmocat here's the code.
this code is work on 1.0.1 but not work in 1.0.3.
I can't reproduce the problem with latest from CVS (OJB_1_0_RELEASE
branch). I wrote two tests simulating the problem, first test doesn't
find a query object and lock the bean object, second test return a dummy
object in query. Both tests pass.
I attached the tests below (the test can be found in CVS OJB_1_0_RELEASE
branch, LockingTest#testWrite_X). Are these tests different from your
problem? Could you locally setup a test case to reproduce the problem?
Are you able to test upcoming OJB 1.0.4 from CVS?
regards,
Armin
