Common Problems
A na niej złotymi zgłoskami ważną rade...
I'm having trouble with a bidirectional association.
When you update a bidirectional association you must update both ends.
parent.getChildren().add(child);
child.setParent(parent);
It's best to do this in an association management method of your persistent class.
I'm still having trouble!
Read the documentation! There's a detailed section about "Parent/Child Relationships" in chapter 16 of the reference documentation including code examples.
Tak to w życiu bywa... że chcesz czy nie chcesz dokumentacje przeczytać warto, a nawet trzeba :)
