FireWatir bug using exists? on a form element with xpath

[Kevin White]

Here is a piece of code that doesn't work in FireWatir 1.6.2:

require 'watir'

Watir::Browser.default = 'firefox'
browser = Watir::Browser.new

browser.goto("http://www.google.com")

searchform = browser.form(:xpath, "//form[@name='f']")

puts "Searchform is #{searchform.to_s}"

You will get this output:

Now, I found something on the net that says that this bug was fixed
way back in 2007:

http://code.google.com/p/firewatir/issues/detail?id=36

So is it fixed, did it recur, is my installation broken, ???

I've coded around it using element.attribute_value() but I really
wanted to use the xpath instead.

Apologies, that code just demonstrates that xpath isn't working right.
I was trying to use .exists? in my code, but the example just is to
demonstrate that the xpath doesn't work at all. If you try to
do .exists? on a form element using xpath, it fails the same way.

Nice catch, there was a spelling mistake while locating the form using xpath. Fixed it. Will let you know when I check in the code
