I used a web page reference - consisting of variables enbedded in a URL - to "goto" the frame directly. I can fill the login fields and click the button, but then I'm sent to another web page which is completely blank.
I may have to skip the login altogether, and do it manually. Hopefully I can still navigate within the web site.
It wouldn't surprise me if the difficulty getting in is intentional - to discourage robots from guessing names and passwords. But I had no trouble automating my access to a different financial institution's site.

I mean to grab the page the frame references, instead of having Watir figure it out.
I'm just trying to think what I'd do with Mech, as I've never heard of Watir until now.

How would I open the frame directly? The frame I want has an ID, even this doesn't help.
An Xpath search fails:
browser.element_by_xpath('//*[@id="main_ID"]')
=> #<FireWatir::Link:0x1a7fdcc located=false how=:jssh_name what=nil>

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.
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.
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)
Failing that, what about opening the frame directly?

"located=false" seems to be Firewatir's way of saying that the object doesn't exist until I ask for it. If I try to use it anyway, I get an unknown object exception
browser.frame("main").html

Looking at the rdocs, http://wtr.rubyforge.org/rdoc/1.6.5/, have you tried
browser.frame("main").html
?

Current problem: logging into a site webpage, Firwatir can see the frames, but cannot access them.

I cannot access any forms etc included in the frame unless I can name / access the frame. Any ideas?
