Rails - Jan 2006 - options_from_collection_for_select - NIL Object

i am kind of desparated

i try with options_from_collection_for_select to get option values, but 
it says


You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.inject

but @customers is not empty ->

def get_customer
@customers=Customer.find_all
end

i have tested it and also the attributes "id" and "name" are
existing!!



<h1> xy </h1>


<%=start_form_tag :action => ''get_article'' %>

<select name=xy>
<%= options_from_collection_for_select (@customers, "id",
"name") %>
</select>

<%= submit_tag "Get" %>

<%= end_form_tag %>

Assuming the rhtml code you pasted is from get_customer.rhtml, I don''t
see anything wrong with the code.
I personally use ''select()'' more often than
''options_from_etc_etc'',
but in this case you''re not working with any objects that exist yet,
but rather passing the selection as a parameter to a different action.
 What you''ve got should be fine.

What do you get when you put <%= debug(@customers) %> right under the
<h1> tag in your RHTML source?
