This function is critical to a project that I'm working on, unfortunately I just found out that it's not working and hasn't been fully developed:

Are there any updates on this issue? Is this planned to be implemented any time soon?
If not, I guess I could try to take a crack at it myself. Do you have any information about how you tried to reverse this so I have a decent starting point to troubleshoot?
