[Saul Simhon]

Hi,

Does anyone know of a quick tutorial that explains how to setup bean validation on the client side?

I'm running into gwt compilation problems and before I start describing them here I'd like to read-up on it first. (my attempt to inferred usage from source was unsuccessful.)

In short, I can't seem to get standard validation annotations (such as @NotNull), validation API, validation groups, messages and custom hibernate annotations (such as @Email) to work!

Your format string is incorrect. As the exceptions say you can not have two dots (decimal separator) in the format String. Fix it and it should work.
