As a rule of thumb, one shouldn't use a string as a boolean unless it's intended to be a boolean like a 0 or a 1. I've encountered many bugs because a test would do:

If there's a valid ID of "0" or "000" or "00000000000000000" it would hit the error-handling code. I suggest checking ID against an empty string, since that's the actual error condition..
