    Today I had the same problem.

    It is caused by this wrong rendering:

    omitting value="" for "None" option result in submitting the label instead of an empty string.

    However to solve this and make the renderer write value="" for the first option just make sure getAsString() never returns null, return "" (empty string) instead.

    Your omnifaces.ListIndexConverter to the rescue :)
