I am trying to get this to work consistently in vCO 5.5.1.
When a weboperator session is already logged in, things go smoothly. However, if I am not logged in yet, it will redirect me to a login page. Upon login, I (sometimes) get an error message. I have attached this error message. If I ignore the message and re-enter the getAnswerUrl at this point (it changed the url upon redirection, so I must re-enter the old URL), then it will work.
Sometimes this error doesn't happen, especially if weboperator was recently used with that specific browser (regardless of session state).
Has this occurred to anyone else? Perhaps I have screwed up a setting somewhere and the redirect link is now broken upon logging in.
