I need simple prefiltering of my table, and learned your tutorial. Your example with {$my->gid} is not useful for my task - simply to show records of list, if data in element "??? ??????" is equal to "?????? ???????? ?????????". There is one test record, with "?????? ???????? ?????????", which should be shown after prefiltering in a list. But it doesn't. Screenshots attached, including test records before prefiltering. What should I do to correct it?
