| You actually don't even technically have to be KVC-compliant (read: implements NSKeyValueCoding), because it will fall back to using reflection. You can just potentially provide a faster implementation if you implement NSKeyValueCoding yourself.

Just thought I would add that clarification. If they are not KVC compliant then you need to write your own custom filtering algorithm.

For example, to filter out items whose "status" attribute value is "hidden", you could use something like the following:
public NSArray filteredItems() { return EOQualifier.filteredArrayWithQualifier(initialArray, new EOKeyValueQualifier("status", EOQualifier.QualifierOperatorNotEqual, "hidden")); }
For more complicated filtering, you can use EOQualifier.qualifierWithQualifierFormat to build your qualifier. -- Sam Barnum 360 Works 415.865.0952

I want to display the contents of an NSArray and WORepetition is the perfect dynamic element to do that. However, I want to complicate the world and be able to suppress some of the entries based on some computation performed on each Array element.
It seems I can do this at least two ways:
(1) ... filter the original NSArray through the computation to make a new NSArray and use that.
(2) ... play games with the processing of the WORepetition so it skips items.
Or (2), use a WOConditional within the repetition to do the filtering for you. This is sort of 'playing games', but unfortunately it's easy rather than hard.
