Allow the activity to return a list?
Hi,
Suppose I have instances of a class named 'Teacher'. Teacher have a list property called 'students'
So for each teacher it have an array of students.
Now I want to make a datapage that loops on all teachers, and add their students to the datapage (I want a list of all students from all teachers). How do i achieve that?
As I am not knowing how, any help would be much appreciated!
Thanks!

Hi,
Please follow the below steps.
Suppose let's assume you have 3 teachers and 9 students. Each teacher associated to 3 students using teacher reference in students list. I used data page's to get results for both teacher and student list.
Step to get teachers list
Inside teachers, write other step to get list of students associated to students. Pass the teacher id to get the number of students associated to teacher.
Step to show the teachers page.

You could first do an obj-browse to harvest the instances of class teacher.
Then, you can code an outer loop either with a java step within an activity, or using the activity looping construct, that loops over the pxResults so it can look at each teacher's list of students.
For each list of students, run an inner loop that picks up each student and adds it to your list of all students.
For other activities already existing that do obj-browse, it is likely that they then have a loop that loops over the pxResults, so to find some examples, try this:
1) Open the method rule for obj-browse.
2) Go to "actions > rule references" on that method rule.
3) Open a number of the listed references. That will show you activi

Thank you.
I am a bit new in pega,
So I made an Obj browse to get all teachers
Then I made a loop inside it
Then I made a loop inside it to get the students.
Now even though I reached the student I don't know how to add him to a list (I can define a local list from parameters tab but I dont know how to add him)
More important, I want to know how to use this list
since this is an activity, I will make a datapage that have a source activity, and give it this activity. But how can i set this activity to return this data
