Here is how you track all commit changes in Cayenne. This includes direct ObjectContext changes or changes originating from pre- listeners/callbacks. Requires Cayenne 4.0.B1 or newer. You will need to add org.apache.cayenne:cayenne-commitlog dependency that will auto-load a corresponding module, and then add custom CommitLogListener objects to receive the events.

If you have callbacks or listeners modifying the context being committed in pre- events, make sure that CommitLogFilter is included in transaction. This is true by default, unless you explicitly call CommitLogModule.extend().excludeFromTransaction().
