NSComboBox text binding

Subject: NSComboBox text binding

How do I get a combo box to update its value binding while an edit session is active? I have an NSComboBox's value bound to a value in an NSObjectController, and the problem is that the user's changes don't always get committed when I want them to.

Specifically, this is a Find dialog, and I'm using a combo box so I can have a history list of search terms. If the user types something and then clicks the Find button, rather than pressing return, then the find text binding doesn't get updated and it searches for the wrong text.

I can get around this by getting [findField stringValue] and putting that in the object controller before searching, but that kind of ruins the point of having bindings.
