Each table should have its own ArrayController if the two tables
represent the data from two different entities. Since you entities are
related I am assuming one entity has a property that is a to-many
relationship to the other entity. Set the ContentSet bindings for
ArrayController2 to be the selection of ArrayController1.
ArrayController2 ContentSet
Bind to = ArrayController1
Controller Key = selection
Model Key Path = (the name of the relationship that represents entity2
in entity1)
This will cause ArrayController2 to always populate the TableView with
the objects selected by ArrayController1
Let me know if that needs to be more clear.
