User test case posted by Charles: Up to now, we've been just using the broker layer. I now have a usecase where we will need to use the ODMG layer. We do not want to use implicit locking; I want my developers to explicit lock each object to an ODMG transaction (implicit locking generates loads of queries for all the proxy collections). It seems that something 'funny' happens if implicit locking is turned off - objects are not marked as being "dirty" when changed - even when they are explicitly lock to the transaction. As I am a complete novice in the ways of the ODMG, I don't really know where to look to sort this issue out so I have added a new test method to org.apache.ojb.odmg.UserTestCases (it should be attached to this email). Essentially, it creates an object and persists it; retrieves and updates it; then flushes the cache, and retrieves it again to ensure the update worked. If ImplicitLocking is TRUE, the test passes. If ImplicitLocking is FALSE, the test fails. I think this is incorrect, and would dearly like this to be resolved. thma's comment: IMO this works as designed. objects must be locked to an ODMG tx before any modifications are taking place. I simply moved the lock two lines up and the test passed.
