Hi, when I try to insert a new element into an existing list and then try to update my list, I get an exception: java.sql.BatchUpdateException: Cannot add or update a child row: a foreign key constraint fails

getItem().getSection().getItems().add(getInsertPosition(),getItem());
getSectionDao().saveOrUpdateSection(getItem().getSection());

What should I do about it?

Regards,
BV
