Hello All,
I have been working on a Core Data application and have fairly good
understanding of the core data, cocoa bindings, and controllers used by
bindings.
I have an outline view that will be predefined to be only 4 levels deep. The
data comes from 9 different entities. Here is the pattern:
* Level 1 . . . . . . . . (Entity A)
* Level 2 . . . . . . .(Entity B)
* Level 3 . . . . . .(Entity F)
* Level 4 . . . . . .(Entity T)
* Level 2 . . . . . . .(Entity C)
* Level 3 . . . . . .(Entity G)
* Level 4 . . . . . .(Entity T)
* Level 2 . . . . . . .(Entity D)
* Level 3 . . . . . .(Entity H)
* Level 4 . . . . . .(Entity T)
* Level 2 . . . . . . .(Entity E)
* Level 3 . . . . . .(Entity I)
* Level 4 . . . . . .(Entity T)
* Level 1 . . . . . . . . (Entity A)
.
.
pattern continues...
Is there anyway I could acheive this using a tree controller and binding?
I am thinking of having a wrapper entity using a custom managed object that
will provide the interface to all the other entities. The wrapper entity
would be bound to the outline view.
Will appreciate all your help in figuring out how to implement this
functionality.
Thanks,
Dan
