I don't know how you do it James. I just did a quick test in a view
and defining a function inline in the view will not provide that
function with access to the local variables outside the function
($html, $form...)
One ugly way of making it work is to make a global reference to the
html helper (if passing it as an argument is not to your liking).
global $htmlHelp;
$htmlHelp = $html;
function testing() {
global $htmlHelp;
debug( $htmlHelp->url('/') );
}
testing();
This is not a fix but a very ugly workaround.
Another possible workaround is to, instead of a recursive function,
try a recursive element.
