License Activation Change and Checking Activation

Hello! How does ObjectDB determine the machine ID? Yesterday I activated our license on my development laptop and today I tried to persist more than 1M objects. ObjectDB told me that it cant't do that because of the evaluation restrictions. Now I activated it again on the same machine and got a different activation code. With this code it works.

It allows me to persist ...

Second time I doEdit produces the error "Attempt to lock a non entity object" session.rollback() is somehow causing the problem (found through debugging) Is this enough information for someone to suggest what might be happening and how to fix it? ...

Problem on JPA Merge Entity.

Hello, I have a problem with the EntityManager.merge() function. I set a property value of an entity (statement) with an other entity (newSingleConstraint). newSingleValue is already persisted. I do this myself (no use of cascade because sometimes the newSingleValue is already in database).   The statement update don't throw exception. And when i try to reload statement the value i have set before is a null value. I check with the Explorer, the statement has a null value on the property and the newSingleValue is present.... - in which methods it is true and in which false? In addition, verify that the same EntityManager is used. If ...
