You must be using RC1 or earlier -- I fixed this issue in trunk last
week, and that fix is now available in RC3. populate() now only
populates the values for which it has keys.

You may want to determine if the value passed is the same as the value
stored in the submit button -- to verify that you didn't get a bogus
submission. We also use the logic internally to determine if a
particular button was used -- you can use the isChecked() method of each
button type (Submit, Reset, Button) to determine if that particular
button was used to submit the form -- this will only work *after* you've
either populated the form *or* run through validations (which populates
the form as well).
