Story runner + selenium-rc + wait_for_xxxx

Hi,

I've got a story working with selenium-rc, but am stuck writing ajax-aware steps.

How are people coding their story steps to wait for an Ajax event to complete?


Here's what I've looked at so far.

$browser.wait_for_element_present
Looks Ideal, but not in selenium-ruby-client-drivers for some reason.

def wait_for_ajax
  $browser.wait_for_condition("selenium.browserbot.getCurrentWindow().ServerConnection.isPending() == false", 2000)
end
This helper looked promising, but it returns
SeleniumCommandError: selenium.browserbot.getCurrentWindow().ServerConnection has no properties

Many Thanks
Andy
