[I'm sure this is not odd at all, but I need just a bit of help]

I have two retain properties

@property (nonatomic, retain) NSArray *listContent;
@property (nonatomic, retain) NSArray *filteredListContent;

and in the viewDidLoad method I set the second equal to the first (so now the retainCount is two, I think):

self.filteredListContent = self.listContent;

and then on every search I do this

 self.filteredListContent  = [listContent filteredArrayUsingPredicate:predicate];

I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected, unfortunately).

Some guidance would help, thanks! Is it correct to not release?
