[rules-users] compare attributes form similar type

Hi I need help to come up with the expression which match an attribute form similar type of bean. e.g matching dob of all Person object. Example: I have Person Object Person{ Date dateOfBith; String name; String gender; } exists (Person ( gender=="male" , <whose dob is first in period 1/1/2012 to 12/31/2012>) ) Now at run time, I am going to get data of multiple Persons. If a person who born first in 2012 among all person data & if he is male --> condition match. But if that person is a female then condition will not match. -- View this message in context: http://drools.46999.n3.nabble.com/compare-attributes-form-similar-type-tp...
