uncaught exception: Empty rectangles do not have centers when going Next/Previous to display: none form elements with form helper
FormHelper._getRectForElement is returning an empty rectangle since the element has been hidden: http://mxr.mozilla.org/mobile-browser/source/chrome/content/browser-ui.js#1807 Do we want to rescan for valid elements everytime we jump next or prev? Could be a speed regression. We could just do a check for visible and remove (or skip) the element. I suggest skipping because there might be other conditions where the element is not hidden. A radio button selection could change visible widgets for example.
It would already help, if the form helper first switches focus, before updating the form elements list, see bug 562223.
This patch prevent the error to show and update the button but did not change the actual behavior of fennec when dealing with a field that hide itself when clicking on it (which I don't think is a common behavior on the web).

Comment on attachment 446497 [details] [diff] [review] Patch I think this is a good fix for dynamic widgets. The current testcase hides a widget if it is focused, but I don't think that is realistic. I think hiding other widgets based on a change to the current widget is more realistic.
