Hi. Take a look at http://myfaces.markmail.org/message/syt73xw5qkmlrcg2?q=COERCE_TO_ZERO
I would suggest you create a String property to receive the value and make the conversion in its setter (for example), or use Juel ( http://juel.sourceforge.net/ ). The problem in using a different configuration to change the behavior is your app will not be 100% compliant with EL...
