Subject Re: Question of new dynamic data binding model of pivot 2.0
Date Fri, 27 Aug 2010 18:27:34 GMT
  I have a question : when we need several variables for function, if 
it's possible, what's the syntax  ?

function toUpperCase(value1, value2) {
        return value2.toUpperCase() + " " value2.toUpperCase();
}
