[rules-users] Another question on how to use map

Hi, I need to put a map into the working memory and make some check on the values I have an object called Student with Id And for every student there is a list of activity. Each activity has date and the time for the activity What I will be putting in the working memory looks as follows: List<Student> studentList = getStudentList(); Map<Student, List<Activity>> studentActivityMap = getStudentActivities(studentList); List objects = new ArrayList(); objects.add(studentList); objects.add(studentActivityMap); ksession.execute(objects); ==================== Now i need to check for every student, if there is/are activity(ies) which needs more than 2 hours. If yes, give an output information which mention, which student and on which day the activity is longer than 2 hours when $studentList : List $std : Student($id : id) from $studentList $activityList : ****how to get the list of activity for the student with this $id from the given map ***** $act : Activity ($date : date, length > 180) from $activityList then (print something out using $id from std and $date from act) Would really appreciate any help and hints here Regards bb -- View this message in context: http://www.nabble.com/Another-question-on-how-to-use-map-tp24181278p24181...
