Help needed on "auto_complete_for" with conditions

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.

From controller…

auto_complete_for :customer, :customernumber, :conditions => {‘deleted_at=’, 0}

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

Any help would be appreciated.
