Rails - Nov 2011 - why is my text_field getting a default value of current_user.email?

I have a form containing a text field along the lines of:

<%= form_for(wizard, :url => wizard_path, :method => :put) do |f| %>
    ....
    <%= form.text_field "gas_credentials[user_id]", :value =>
wizard.gas_credentials[''user_id''] %>
    ....
<% end %>

Mysteriously, when wizard.gas_credentials is nil, the text_field gets
initial text equal to the current_user.email (which in this case is
admin-OMsI0saeytcAvxtiuMwx3w@public.gmane.org).  At the very least, I''d
expect an error trying to call
[] on nil.

What''s especially odd is that the wizard model knows nothing about
current_user, so I don''t see where it''s getting that value
from.  Can
anyone shed light on what might be happening, or at least how text_field
decides to compute its :value?

TIA

Doh!  The answer: browser autocompletion.  I''m leaving this post in 
place rather than deleting it out of shame in the faint hope that it 
might save someone else a few minutes of head scratching.

[silly forum code won''t let me edit previous reply.]

To prevent autocompletion, you can do something like:

    <%= form.text_field "gas_credentials[user_id]",
            :value => wizard.gas_credentials[''user_id''],
            :autocomplete => :off
    %>

That''s because it''s a mailing list... and even if every other
subscriber let you come around to their house and edit their emails, I
wouldn''t ;-)

The "ruby-forum" is just a wrapper for the Google Groups list.
