I had a thread over at http://www.kriesi.at/support/topic/current-menu-parent-specific-to-woocommerce?replies=1#post-78584 and it was indicated that the Menu Walker Class was in need of an update. It seems the thread is closed and I can't comment anymore.
Is there an update on this? I'm stalling with the client. I've made other mods to the code so a "full on" update would be more of a pain for me to implement than just knowing the files that need to be updated?
Any insight would be most helpful.
