Hello Gavin,
This may not be elegant enough ;-) but you could just wrap the
contents of the WORepetition in a WOConditional.

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.
The former isn't hard, obviously, but since WORepetition is already
iterating across all the element of the array, I wonder if the
latter is possible.
I have a *.wod which is, in part:
LoopOverUsers: WORepetition {
list = userList;
item = thisUser;
}
and I have implemented getThisUser / setThisUser methods in
the component, so control passes through these methods for each
element of the array. But is there something I can do to defeat
WORepetition's rendering of some elements ? My guess is NO, but
there are smarter people than I on this list ... thanks, Gavin
