Error description

• String concatenation of variables within JavaScript might cause
  an exception similar to the following exception:
  
  Internal Script error
  com.lombardisoftware.core.TeamWorksRuntimeException: Exception
  during converting JavaScript to TWObject. The conversion of obj
  org.mozilla.javascript.NativeObject to TWObject is not valid.
  
  Reason:
  Java Class org.mozilla.javascript.ConsString is not registered
  as supported class for the SymbolTable
  
  For example
  
  function Concat(s1, s2, s3)
  {
      return s1 + s2 + s3;
  }
  var s1 = Concat("test", "1", "2");
  var s2 = Concat("test", "3", "4");
  

Local fix

  return (s1 + s2 + s3).toString();
