JPA, orphanRemoval, Problem

[bnr]

Hi,

I have a problem with JPA and (cascade={CascadeType.ALL}, orphan Removal=real). I have a project that can have some comments and some configurations. The configurations can has some comments, too.
- If I add a comment to the project which has a configuration, then I got the followed error.
- If I add a comment to the project that has no configurations, then it works well.
- If I add a comment to a configuration, that works also well.
- If I remove (cascade={CascadeType.ALL}, orphanRemoval=true) from the private List ; on the Configuration.java Entity, then all scenarios works well without errors. But, I have a Comment corps in the DataBase, if I delete some configurations.

I can't see the problem, how it does not work with cascade.
