So I have an NSDictionary where each key is the entityName of a
descendant of EOGenericRecord and each value is an NSArray of  the
corresponding entity. Can I bind one of these arrays to a control's
list in WOBuilder?

NSDictionary myDictionary

bind to (NSArray) myDictionary.objectForKey("myEntityName") 

	It's even better than that: myDictionary.myEntityName.

NSDictionary conforms to the NSKeyValueCoding protocol, so myDictionary.myEntityName is shorthand for myDictionary.valueForKey("myEntityName"). However, in WOBuilder, you'll need to manually enter the dictionary key because there's really no way that WOBuilder can present the possible dictionary keys.
