I've got a tableView with a data source as an NSMutableArray. I want to filter information in this tableView by a user entered criteria, however, I can't find anything in NSTableView or NSTableView delegate that would allow me to do that. It seems the only way is to create a second array that contains the filtered(or non-filtered) results and use that as the data source. It seems like there should be an easy way to filter a TableView, given that it's probably done a lot, so am I missing something?
Got a tip for us?

Ok, so I've got my tableView that's bound to an NSArrayController. Based on what I read, I created a method that returns an NSPredicate object which is then entered under the bindings screen for FilterPredicate of my NSArrayController. However, it's raising an exception whenever I run the program. This is the error message
This is the code for my NSPredicate method
Any thoughts on what I'm doing wrong here?

Code:
-(NSPredicate *)tableFilter
{
NSPredicate *aPredicate = [NSPredicate predicateWithFormat:
@"ANY partsList.partNumber contains[c] %@", searchValue];
return aPredicate;
