[rules-users] Double Referencing

[Michael Anstis]

Have a read about nested accessors in Expert's documentation.

You should be able to achieve this using the MVEL dialect for your rule:-

when
    Person( dob.year > 1972 )
    ...

The "then" part of a rule is either pure Java or MVEL and consequentially
provided your RHS is valid syntax for whichever dialect it should be OK.

With kind regards,

Mike
