Mysterious crash in loaded nib

Hi, all,

I have a nib that I load with:

- (id)init {
	if (nil != (self = [super init])) {
		if (![NSBundle loadNibNamed:@"SearchController" owner:self]) {
			[self release];
			self = nil;
		}
	}
	return self;
}

and it works beautifully--except for two items, a text field and a popup button. These items are added to a toolbar, whose delegate belongs to a different class, so I use cover accessors to gain access to these interface items. Here's one of my accessors:

- (PTextField *)toolbarSearchField {
	return search_field;
}

I have also tried using "return [[searchField retain] autorelease]".

I use the following code to add one of the items to my toolbar (it's the same for the other item in terms of layout):

	id toolbarSearchField = [search toolbarSearchField];
	[toolbarSearchField retain];
	[toolbarSearchField removeFromSuperview];
	[item setView:toolbarSearchField];
	[toolbarSearchField release];

Somehow, I'm getting crashes on the -retain call! Once it was an EXC_BAD_ACCESS, and another time NSLock was receiving the message.

It is of course clear that my control is getting released before I get the chance to use it.

But how? These toolbar items are located within a top-level NSView in my nib file--and I have an IBOutlet set to this NSView, so (if previous postings are correct--and also if my experiences with - +loadNibNamed:owner: lead me to the correct conclusion)--the top- level items should be retained automatically.

Does anyone have any inkling as to what's going on?

Cheers,
	Andrew
