if I use a <t:formattedfield format="long" ... /> and if I enter the value 9.223.372.036.854.775.808 or greater and if I leave the edit field, then there will be a java.lang.IllegalArgumentException in javax.el.BeanELResolver.setValue() on client side.
The value above is 2^63 which is java.lang.Long.MAX_VALUE + 1.
