Here is a rough sketch of my datamodel. If you like I can take a
screenshot and post a link to it.
Client
---Project
----Todo
Writeoff
---Item
By each entity having its own group, I am refering to say Mail.app how
it has "MAILBOXES", then "REMINDERS", or in iTunes "DEVICES", and
"LIBRARY". My intention was to have multiple group nodes as well as
multiple child nodes.
On regards to your project, here you go:
Once it loads, nothing is clickable :(
In the debugger, this is what it says:
2008-07-25 12:35:01.031 SortedTree[1526:10b] *** -[ESTreeNode
isSpecialGroup]: unrecognized selector sent to instance 0x133d20

I have a NSOutlineView hooked up to a NSTreeController, which has
multiple entities inside of it. I would like to know how to set it
up having each entity having its own "group". I have downloaded
Jonathan Dann's example, which compiles but freezes. I can see how
his Core Data model works, but I already have mine set.
Haha! That's great, sorry about that. I'm interested to know where
it freezes, can you tell me more so I can fix it, please!
Can you explain what you model looks like in a little more detail,
and what you mean by each entity having its own group. Do you want
a single group node entity or multiple group nodes as well as
multiple child node entities?
Do I need to have both of my entities have a parent entity in which
my NSTreeController reads from that one parent entity?
If I understand you correctly, the general concept it to have a
single abstract "TreeNode" entity. This is the entity that the tree
controller concerns itself with, you then can make as many concrete
entities as you like that inherit from your abstract one.
