I'm just getting starting with creating a Nintex workflow and I was following a step by step tutorial on implementing a state machine. I'm stuck when I try to add the "Change State" action. When I go to configure the action, the dialog " Configure Action - Change state" comes up, and the "Next State" drop down is displayed. This drop down never populates with any states I've created, and it only allows a selection of "Other Value"... I've pasted a screen shot below. I also ran the developer console in chrome and noticed that this error pops up in the console "Uncaught TypeError: dropDown.options.insertBefore is not a function" when the dialog\modal loads.
I've tried in IE,chrome,firefox and with different accounts with no luck. Am I missing something? Has anyone else experienced this?
