Yes: you misunderstand your need. Inputting one or more zeroes is valid 
for your use case of wanting an integer between 1 and 254. For integers, 
001 == 1 -> valid. So 00 is 'intermediate', because it could still 
*become* valid input. Also, making input like that impossible hinders 
your users. What if somebody accidentally typed in 102, and wanted to 
type 202. He would delete the 1 (thus temporarily get 02) and type a 2. 
You want to prevent that, as the input may in your vision not start with 
a 0. Not very user friendly.
