In the spreadsheet (with class Country) you would have a column such as: CONDITION Country name in ( $param ) Test whether name is one from a given set "Austria", "Germany", "Switzerland" "France", "Canada", "Belgium"
This is the generated rule: rule "InTest_18" when $country: Country(name in ( "Austria","Germany","Switzerland" )) then System.out.println( "German is spoken" ); end You should be able to retrofit the template from this. (Why do you need a template when you have a spreadsheet?) -W On 14/06/2013, Jason Allen <jason.al...@data-sign.com> wrote: > Hi All, > > I'm trying to determine if it's possible to process arrays of data using > Rule Templates.
