I have assigned students in a category which has some courses.I assigned using Assign roles link at category page.
These students are shown in course particpants list with student role but not in course assign roles list.
when i try to search the students through Administration->Browse list of users by adding filters as course role=student and selected the category (where i assigned students).the students assigned at category level are not shown in the search results.
I think as these students are shown in course participants list with student role,the search query should show up these users also along with other course members.
Resolution: I think the query in function get_sql_filter($data) in moodle/user/filters/courserole.php should be modified accordingly
