Ian,
Why would '2100-100' fail by adding WHITE, MARY?  Is it because you would have an extra (i.e. 3 ) in the list?  Is this the test that you are trying to evaluate?

Thanks

Hello all,

I am new to Drools…

 

I have a scenario

 

Each fact object will have the structure:

 

Title

   Proprietor Group

      Proprietor Name

 

E.g.

            2100-100

                        J2 ˝ share

                                    SMITH, JOHN

                                    JONES, FRED

                        T ˝ share

                                    BROWN, CHARLIE

            2100-101

                        J2 ˝ share

                                    BROWN, CHARLIE

                                    JONES, FRED

                        T ˝ share

                                    SMITH, JOHN

            2100-102

                        T ˝ share

                                    BROWN, CHARLIE

                        J2 ˝ share

                                    JONES, FRED

                                    SMITH, JOHN

 

The group names and the proprietor names must be the same across each Title.  The scenario above is a valid case. A failed case would result for Title 2100-100 if we add an extra Proprietor name e.g. WHITE, MARY.

 

I anticipate having one rule to cater for this.  I am hedging towards the ‘collect’ operator but cannot get a clear picture on how to implement it.
