[rules-users] operator choices in GUVNOR for decision tables

[Costello, Robert]

I see a limitation to the operators in org.drools.decisiontable.parser.
LhsBuilder

    static {
        operators = new HashSet<String>();
        operators.add( "==" );
        operators.add( "=" );
        operators.add( "!=" );
        operators.add( "<" );
        operators.add( ">" );
        operators.add( "<=" );
        operators.add( ">=" );
        operators.add( "contains" );
        operators.add( "matches" );
    }

Not sure if this is used in Guvnor for the web view of decision tables,
but I wonder if this is expanded in the supported version?

Using Drools 5

I'm using a decision table in Guvnor and want to see if a value is in an
array or list, but I don't see list or collection operators available,
such as 'in', or 'contains.'  

How do I see if '5' is in [5,10,15,20] without writing a function or
otherwise writing something custom?  What am I missing?  Is there a way
to variablize an array without passing in a class? 

Thanks, 

Robert Costello
