How to add custom fields with dinamic values (not stored)

[jpmoraez]

Hi folks,

Im adding a new custom field that doesn´t need to have its value stored.
I´ll calculate this value through a simple query and display it only at view_all_bug_page.

So I just only want to know the better way to make theese query populate my custom field...

will I have to make a hard code at filter_get_bug_rows method to add this query ? .. for example


thanks
