How do I configure the relationships in these Grails classes to cascade properly?

Here's a simplified version of the classes I'm using:

class Foo {
    Bar importantBar

    static hasMany = [ bars: Bar ]
}

class Bar {
    static belongsTo = [ foo: Foo ]
}

Now, the Bar that's in the Foo class as importantBar can also exist in the bars set. What I want to have happen is when I delete a Bar, and it happens to be an importantBar, I want it to be deleted from both places in the Foo object. Declaring static hasOne = [ importantBar: Bar ] has not worked either, as when I add a new Bar to the bars set, it is automatically being set as the importantBar property of the Foo class. I don't want that to happen.

Is there any sort of mapping I don't know about that can do what I'm asking?
