Hello All,
I am having a strange issue with a Hibernate collection and difficulty debugging it. I work in a multi-developer team and my unit tests appear to have suddenly started breaking. I have a mapping that was working perfectly until now, now I am getting a strange error whenever I try to save a collection. I have an outer object that contains a collection of inner objects. The inner objects save just fine in isolation. The outer object saves just fine if it has no inner classes (it’s member variable of collection List is null). The outer object also works perfectly if the list has a count of one. When I add 2 or more objects to the list, I get the error below. To make the issue even stranger, I’m using the identical @OneToMany syntax in many other instances without issue (the mapping patterns is repeated about a half-dozen times throughout my application.
Any help troubleshooting this issue is greatly appreciated.
Steven
Here's the error:
