Mechanize users - Jun 2010 - submit button param is duplicated when a form is submitted a second time

Hello,

Below I''ve pasted a simple example to reproduce what I say in the
subject. I wonder...
Is it a bug? Is there any workaround?

Thanks!


require ''rubygems''
require ''mechanize''

agent = Mechanize.new
page = agent.get(''http://google.com/'')
google_form = page.form(''f'')
google_form.q = ''ruby mechanize''
page = agent.submit(google_form, google_form.buttons.last)
pp google_form.request_data
page = agent.submit(google_form, google_form.buttons.last)
pp google_form.request_data

I think it''s working as expected. You probably want to do this:

   require ''rubygems''
   require ''mechanize''

   agent = Mechanize.new
   page = agent.get(''http://google.com/'')
   google_form = page.form(''f'')
   google_form.q = ''ruby mechanize''
   page = agent.submit(google_form, google_form.buttons.last)
+ google_form = page.form(''f'')
   pp google_form.request_data
   page = agent.submit(google_form, google_form.buttons.last)
+ google_form = page.form(''f'')
   pp google_form.request_data

I.e., use the new form from the new page, rather than continuing to use the
old form that you added the button to. Or, if you really want to use the old
form, for some reason, I think you could just do this:

   require ''rubygems''
   require ''mechanize''

   agent = Mechanize.new
   page = agent.get(''http://google.com/'')
   google_form = page.form(''f'')
   google_form.q = ''ruby mechanize''
   page = agent.submit(google_form, google_form.buttons.last)
   pp google_form.request_data
-  page = agent.submit(google_form, google_form.buttons.last)
+ page = agent.submit(google_form)
   pp google_form.request_data

I really want to use the old form, but submit it with another button,
so what you propose doesn''t work for what I want (as it submits the
form with the same button I used the first time).

I''ve implemented a reset_clicked_buttons to work around this, but I
think it should be supported, otherwise how do you "mechanize" a
browsing sequence like...
- user visits google.com
- clicks on "Google Search"
- goes back
- now clicks on "I''m Feeling Lucky" (browsers only send this
button,
not the button that was clicked before, but Mechanize would send both)

Thanks!
