Bug Report

Current Behavior:

i am not sure why this is getting thrown in random places:

angular.js:15544 TypeError: str.split is not a function
    at splitClasses (stateDirectives.ts:685:47)
    at Array.map (<anonymous>)
    at getClasses (stateDirectives.ts:689:18)
    at update (stateDirectives.ts:692:32)
    at processQueue (angular.js:17922:37)
    at angular.js:17970:27
    at Scope.$digest (angular.js:19089:15)
    at Scope.$apply (angular.js:19477:24)
    at done (angular.js:13320:47)
    at completeRequest (angular.js:13577:7) 'Possibly unhandled rejection: {}'

Is there something that i am missing. We were on a very old beta 1 release of ui-router that never gave us 1 issue. Upon upgrade we started getting these errors on the console, BUT everything seems to still work as designed.

Has anyone every seen this?

it's because sometime it's not stirng so first use

str.toString().split()

and
and given the error it looks like str is an array make sure before using the split function and if it still gives that error then use the toString() method and try to split
