Thank you Kevin. I really appreciate your answer. But it doesn't work. I think the method that .NET encode empty string is different.
Whatever I contain arguments with empty string or not(i.e, I contains not empty string), $Data(id) value is always 1. Therefore id value is exist, but cache doesn't recognize it. I don't know the reason why. - Song "kevin furze" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > InHyuk, Song wrote: > > 1: ClassMethod FindAdmission(id As %String) As %XML.DataSet [ > > WebMethod > > > normally you can set the default in the parameters using ="" > > > ClassMethod FindAdmission(id As %String = "") As %XML.DataSet [ > WebMethod > > will this work here? > > kev >
