$fieldarray problem [message #2387]

Hello,I got this little problem:

I have 2 tables courses and students;

There is a parent relationship between the tables.

Snr table is : courses
Jnr table is: students

In the List1 of courses i want to see also the number of students attend the relative course.

I used _cm_getExtraData, doing a count of row in table students and
_cm_ChangeConfig to add the new field, 'partecipants', in the $fieldarray wich contains the count of students.

The problem is:

$fieldarray cointains only the first entry of the table courses.
How i can get the rest of data (rows)?
I hope I've been clear.

Thank you,

Fabio

Both _cm_getExtraData() and _cm_ChangeConfig() are called once per iteration, and only need the first record. If you wish to perform processing on every record in the list then use either the _cm_post_getData() or _cm_getForeignData() methods.
