Help needed on "auto_complete_for" with conditions

I have the following in a controller, where the view allows the user to
enter a partial customer number and have auto-complete provide the list
of matches. It was working fine until I added a condition (to see if it
would work). Here’s the code and the (incorrect?) SQL generated. Is
this a bug or am I going at this the wrong way? It seems like the SQL
is not being generated correctly, even though the controller is
processing the condition.

Fromcontroller…

auto_complete_for :customer, :customernumber, :conditions => 

{‘deleted_at=’, 0}

Fromdevelopment.log…(note: my “customernumber” field is a string, not
an integer)

Processing

Any help would be appreciated.
