tf does not prompt for mandatory user inputs

[raghavan-mk]

output from command prompt on trying to check in

tf checkin -noprompt ********
[Checkin] Execution of the TFVC command line failed unexpectedly.

We have some mandatory inputs to provide while checking in like code reviewer. With no prompt option i am not able to provide it and i guess that is why it is failing to check in. The same when i do come command prompt removing noprompt, i get the popup to which i provide details and check in goes through fine.
