title: String Arrays in Guvnor rule
body: <p>I am having some difficulty in understanding how a String[] can be represented in a Guvnor rule. How can an array of strings be passed to a Java method that uses String[] as an argument from a rule in Guvnor?</p>
  
  <p>I keep getting mismatched input errors, Error Code 102 when I attempt to validate the rule in Guvnor.</p>
  
  <p>Any pointers/tips welcome</p>
  
  <p>In the following rule, comm is a global object with a function sendMail with the function signature (String[] recipientlist, String alertType, String message) </p>
  
  <pre><code>rule "list-email"
      dialect "java"
          when
              $result : Grade( subject == "Math" , $marks : mark &gt;= 99.0 )
              $emailList : "{xyz@abc.com, fgh@def.com}"
          then
              comm.sendMail($emailList, "High Grade Alert", "Scored: " + " Marks:" +       Double.toString($marks));
  </code></pre>
