It certainly shouldn't be doing that...

I wasn't sure exactly what accessor methods you have.  Have you 
implemented a set<Array> method that looks like this:

- set<Array>:(NSMutableArray *)newArray {
    // ...
    array = [newArray copy];
}

?

If you've used 'copy', note that it returns a new *immutable* array. 
You must use 'mutableCopy'...

If this isn't it, could you give a little more detail?
