SuccesS!!!! :D:D:D
Ok I have success, but I stepped away from what you told me,,, in a way.
What I did was:
In the AwakeFromNib method of the parent Controller, (the one that
holds the UserListController and the InvoiceEditionController).
-(void)awakeFromNib{
if(_userListController == nil){
_userListController = [[UserListViewController alloc]
initWithNibName:@"UserListView" bundle:nil];
}
[_myUserListView addSubview:[_userListController view]];
[NSBundle loadNibNamed:@"InvoiceEditionView"
owner:_userListController];
[_myContentView addSubview:[[_userListController
_invoiceEdViewController] view]];
}
So I instantiated _userListController normally, passing the Nib file
that will control. then well add the view and then I load the .xib
"InvoiceEditionView" and set the owner to _userListController. Now
before going to the next line in this code:
In UserListView .xib, I added the NSArrayController that has the data.
In InvoiceEditionView.xib, I set the class of the File's owners to
UserListViewController, then I place an NSObject and called
Controller, and the class of this Controller is
InvoiceEditionViewController.
In UserListViewController I declared a IBOutlet and connected to the
Controller I have just placed in InvoiceEditionView.xib. then I
connected from Controller the outlet view eventually to the view that
is in the xib.
Then in the view I placed the label and bind the value to File's
owner (Which is USerListViewController) and the Model Key Path to
_userListArrayController.selection.completeName.
and IT WORKED!! I will try placing a NSObjectController and setting
the label's value to it and see what happens. :D:D:
Thanks for the help

Keary Hello:
This doesn't appear sensible, and you may have a number of
problems. First, make sure that InvoiceEditionViewController is
being instantiated
this is what Im doing: in the awakeFromNib
if(_userListController == nil){
_userListController = [[UserListViewController alloc]
initWithNibName:@"UserListView" bundle:nil];
}
if(_invoiceController == nil){
_invoiceController = [[InvoiceEditionViewController alloc]
initWithNibName:@"InvoiceEditionView" bundle:nil];
}
[_myUserListView addSubview:[_userListController view]];
[_myContentView addSubview:[_invoiceController view]];
[_invoiceController setUserController:_userListController];
You mentioned having an outlet from the UserListViewController to
the InvoiceEditionViewController--this can only be accomplished in
the InvoiceEditionViewController is in the UserListViewController's
nib, in which case you are instantiating two different
InvoiceEditionViewControllers and hence experiencing problems.
If the InvoiceEditionViewController is *not* in the
UserListViewController nib, the above should work fine, except still
consider the NSObjectController but with the correct key path.
properly. Second, simply have a reference to
UserListViewController in InvoiceEditionViewController, which can
be an outlet if
ok done I have now there this : IBOutlet UserListViewController *
userController;
This is only useful if the InvoiceEditionViewController is
instantiated in the UserListViewController nib, If it is, then
chances are that the InvoiceEditionViewController is not being
instantiated correctly unless you have overridden -init or -
initWithCoder:, depending on the super class.
InvoiceEditionViewController can be sensibly instantiated via xib,
or set by other means. I recommend then to have an
NSObjectController in InvoiceEditionViewController.xib whose
content is bound to
UserListViewController.NSArrayController.selection (using correct
ivar/property names, of course).
Ok I tried but when wan tto bind the labels to show the details I
bind it to the NSObjectControlled I just configured, and the
controller key goes to selection, which its not good, so whe I run
I see its NO Selection. label.
No, "selection" is the correct controller key for data access. It is
confusing for an object controller as there will only be one
selection (or none), but that is how it works.
I did instead was to place an NSArrayController (users) in IB and
bind the contents to
userController._userListArrayController.arrangedObjects.
then the labels I bind the values to users, and the controller key
to selection and the path to the attributes of the entity.
And it works 50%, I can see the values., but when I select another
user, the values dosn't change, it's seems its getting only the 1st
value of the array.
Of course. You are creating a whole different array controller that
has its own selection semantics. Bindings are automatic but not
magic. Scrap the array controller approach. It won't work. Do an
NSObjectController instead.
Google "binding across nibs" (you may need to try a few variations
on the preposition for best results) and you will find numerous
discussion and techniques.
