Maybe you don't need the hidden field. How do you come up with its value
in the first instance, before you paint the page for the first time in a
session? Could you calc the value on the fly in the page-level
onBeforeHtmlOutput event and stick it in an instance variable? If you
could recalc the correct value each time, you wouldn't need to send it out
in the hidden and get it back.
In general, you should be careful about using getValue on fields on the way
out the door. I try to restrict it to values that I am getting back from
the page, precisely because of timing issues such as you seem to be
encountering.
