Thanks for the great advice! That did the trick and made me realize
an even simpler solution to my needs in the process.
I needed to iterate the pages in reverse to store the page ID of the
last <li> element of each <ul> element before allowing the walker
class to do its work. This allowed me to assign a CSS class to the
stored elements in the Walker class's start_el function.
Both you guys have a great weekend and thanks for the help.

wow; i was just looking at the wordpress source; not the prettiest
code ive
ever seen..
anyway; in what context do you intend to use the subclass? why
dont you
just create a
proxy instead?
eg. (php4)
class WalkerProxy {
var $walkerInstance = null;
/**
* constructor
* accept an existing walker instance or create one from scratch
*/
function WalkerProxy($existingWalker=null) {
if(!is_null($existingWalker) && is_a($existingWalker,
'Walker') {
$this->walkerInstance = $existingWalker;
} else {
$this->walkerInstance = new Walker();
}
}
/**
* walk
* do custom WalkerProxy stuff then invoke the underlying
Walker's
walk() method
*/
function walk($elements, $to_depth) {
//// do something custom here
return $this->walkerInstance($elements, $to_depth);
}
/// .....
}
