>From what I am seeing in the code, it isn't about ForEach not properly
validating, it is about the fact that if no arguments are passed,
there is no entry in to the validation loop. So it doesn't get a
chance to throw the validation errors. So you'd experience the same
problem as before when not actually passing in a value. If you passed
in a blank id or an id that wasn't an integer that would catch it and
throw the validation error accordingly.
