What is selected in FolderTreeController's outline view? Your code
above implies that you select a non-root folder prior to adding a
new job (to the non-root folder). The "allDescendantsJobs"
relationship only has something in it for a root folder. Are you
selecting a root folder and seeing no jobs?
I'm selecting root folders, non-root folders, or leaf folders, and
seeing no jobs in any of those cases. If I select a particular folder
(of any depth in the tree), create a new Job, quit, unbind the content
set, and build and run the program, the Job I created but couldn't see
is present, with it's folder and rootFolder set correctly.
Additionally, the following code only prints the name of the the
current folder:
id adj = [folder allDescendantsJobs];
NSLog(@"Current Folder: %@.\n",[folder name]);
for (id i in adj)
{
NSLog(@"Job: %@\n", [i name]);
}
BUT,
id kids = [folder children];
NSLog(@"Current Folder: %@.\n",[folder name]);
for (id i in kids)
{
NSLog(@"Child: %@\n", [i name]);
}
Prints out all the folder's children just fine. Weirder,
id jobs = [folder jobs];
NSLog(@"Current Folder: %@.\n",[folder name]);
for (id i in jobs)
{
NSLog(@"Job: %@\n", [i name]);
}
Works as expected as well, printing out only the current folder's
jobs. All of these were placed at the top of newJob: from my previous
message. I've double-checked the model for typos or unselected
inverses, and it all checks out. Are there issues with multiple
relationships between the same entities?
