[rt-users] Problems with user Custom fields

[Wolfram Huettermann]

Hello,

I have a big problem with user custom fields. I will  describe it that way:
I habe a use with the real name "Max Mustermann" with the id #13159. He 
possesses a  user custom field  with  the  id #17 and the name "test". 
It is a text field and its value is "foo".  It is supposed to be empty 
for all other users.

One day, I change that costumfield of that user to "bar" and I have a 
collection of Users called $Users which I intend to limit that way:

$Users->LimitCustomField(
               "CUSTOMFIELD" => 17,
               "OPERATOR" => "=",
               "VALUE" => "foo");

The very trouble is that this collection still enlists "Max Mustermann" 
as "foo" is a former customfield value of the customfield #17.

This is not  very helpful. Nevertheless, I want to enlist all users 
whose CURRENT value of  customfield  #17 is "foo". Is it possible?  Or 
is it impossible?

Thanks in advance,


Wolfram
