Assigned user is not displayed in any module

[theodore]

Hello,

I deleted the two earlier user from users table (directly in db) and create some new.
But in the box where there is a js drowpdown to assign an user to a task/meeting/call, the only users appearing are the two earlier users.
In the Task List view they appeared too in the task that were assigned to them. But when I assign a task to a new user, the assigned user cell is blank.
The ealier users were deleted one month ago, and I think there is a cache problem. But I tried quick repair in admin module and some other buttons, and I also delete everything in cache/module folder without any result.
Server is Linux 2.6.26-1-amd64
Mysql is 5.0.87-d10-ourdelta65
Php is PHP 5.2.6-1+lenny8 with Suhosin-Patch 0.9.6.2
Sugar Crm Version 5.5.0RC4 (Build 6621)

Any help greatly appreciated

I'm sorry for my very bad english

The trick was :

function get_user_array($add_blank=true, $status="Active", $assigned_user="", $use_real_name=false, $user_name_begins = null, $is_group=' AND portal_only=0 ', $from_cache = true)
to->
function get_user_array($add_blank=true, $status="Active", $assigned_user="", $use_real_name=false, $user_name_begins = null, $is_group=' AND portal_only=0 ', $from_cache = false)
