Using Watir I have been able to isolate this button element:
<BUTTON id=authButton class=commandButton onmousedown="$('newOrder:hiddenAuth').click();">Authorize Payment</BUTTON>
Here is my watir code:
$browser.div(:id, "rSide:j_id750_body").table(:index, 0) [1] [0] .button(:index, 0).click
I was able to see I'm on the <button> by using watir's "flash" method to highlight the button. For some reason I am unable to actually click the button. I think it might have something to do with the onmousedown code but I really don't know. Any help would be greatly appreciated.
