Where can I find the convertBoolean?

[Cosma Colanicchia]

Hi,

I'm searching for the convertBoolean converter, I need it to use a <h:selectBooleanCheckbox> component with a non-boolean backing bean attribute (I have a "1" / "0" database value).
I can't find this component in by tomahawk release.. is it still in the sandbox? Where can I obtain a sandbox jar? (or how can I build it myself).

Thank you
