Just a side note:
I was talking with Travis over at Build with Structure and Chris BNI in regards to the fact that Structure and Safecracker do not update the Structure URL Field because it’s in a tab.
Anyway, Travis has said that with this announcment they will be supporting safecracker now sometime soon:
The news just keeps getting better.
Also, I was having an issue with VZ URL field type on the front-end using Safecracker. It wasn’t quite working the way it should and Eli from http://elivz.com stayed up late last night and came up with a quick fix which should be released sometime soon as well.
So a big thanks goes out to everyone mentioned!
