Hello,
I have two core data entities, Category and Project. Category is
related to Project using the "project_rel" (one to many). Project is
related to Category using the "category_rel". The inverse is set for
both of them. So basically I want to list all projects within a
category.
I have a tree controller that is setup using the following bindings:
Object Controller: Mode=>Entity Entity Name=> Category
Key Paths: Children => project_rel
Last but not least, I have a button hooked up to the add method on the
NSTreeController. I have also tried the addChild method, and written
my own method to programmatically add the category entity and all
result in the same error. When I click the button I get the following
error: the entity Category is not key value coding-compliant for the
key Project
This has got me stumped and everything I find says that I have this
setup correctly.
Thanks in advance
