Question

I’m trying to get my code(developed with Watir for IE8) working with watir-webdriver and IE9.
Currently I have an issue with waiting.

For example

Watir::Wait.until{browser.button(:value, "Login").exists?}

It doesn’t wait and gives me next error

Tried same script with IE8, and have the same issue.
Of course I can workaround it with sleep, but it’s not very good idea.
If I do sleep for few seconds before wait, it works fine.

Try this:

browser.button(:value, "Login").wait_until_present
