When you put declare a bidirectional relationship in a OneToMany and ManyToOne relationship and put a cascade=CascadeType.ALL on the OneToMany declaration is the cascade in both directions or only on the OneToMany relationship? In other words if I have a airplane with passangers and I remove a passenger will it delete the airplane? And how do I get it to set a ManyToOne relationship null if the otherside is deleted? I have been working with Cascades but I just can't seem to get it to work right.
