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

[Costello, Robert]

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,
