this should not be like this. I guess you made a mistake here.
if you really get the original work flow, you should use if insteadof while.
Warning: this fix might be WRONG, so take good care about it.
If your original codes be a typo, and what I fix now is the function you want, that is OK.
But if the original codes works exactly what you want, then you should change while to if
either of the two fixes should happen.
