Accessing a list index in a field value

Question

Howdy all,
I am setting up a field loop on a form I am modifying. It is the Question Login form. Instead of looping through all the questions, I am calling a rule to return a list of indexes. The indexes are actual int values. For the field names and values of the questions, I am using references that look like "questions[#$(index)].question". When I view the form using Tools -> Test, it is showing the right number of rows. When I view the form by pushing the "Forgot Your Password?" button on the IdM login, I don't see any of the questions. Does anyone have any ideas why this might be? It seems like it should work!
Thanks,
Jim

Well, like most things in IdM, I was able to get it to work, sort of....
I stopped trying to reference the rule, and instead unrolled the rule logic in the <expresion> for the field loop. This works pretty good. For the question display, my custom policy is now being played out. Basically we are requiring question #0. With the first question we prompt for an student ID value. Then two random questions chosen from the next 5 questions. Finally, the question at index #6, the first user supplied question is asked.
So far so good.
Now, the problem comes when I try to authentication using the questions! I was testing with the policy of all questions being required. This seemed not to work, every time I submited the new form, it would give me the error "One or more Questions not answered." Sooo... then I went back to the random question policy with the same number of questions I answered (4). This became problematic because now my questions[*] array only contained 4 random questions. There was no guarentee the ones I require were there, and my rules that generate random indexes were generating indexes greater then 3, so there was no guarentee that all 4 questions would even show. So now I've settled on the 'any' option for required questions. Here's where it gets weird. If I specify 4 required answers to any questions, then I ALWAYS get "You must correctly answer at least 4 questions". Which I am. 3 policy supplied ones and 1 user supplied question. I've double and tripple checked my answers, to make sure they are correct. If I set it to 3 questions then it sometimes works and sometimes doesn't. It is very inconsistant. Sometimes I'll answer all 4 questions and it will still say "You need to answer atleast 3 questions". I can't make it act consistantly at all. I'm pretty much out of ideas at this point....
