If you RTSL a bit you'll see that calling browser.frame creates a new element but doesn't validate it actually found anything. When you call the html method it first asserts that the object exists and throws an exception if not.<div>
<br></div><div>The located=false comes from the element#inspect method, (which just taught me a new Ruby idiom: !!@o returns true if @o is a valid object or false if it isn't.) So located=false means that the object never existed, nor will it ever.</div>
<div><br></div><div>While poking around I saw a locate_frame method. Maybe that might work better? (It's actually possible that .frame uses locate_frame, I didn't trace it far enough)</div><div><br></div><div>Failing that, what about opening the frame directly?</div>
