This makes it impossible to enter a social security number on the Chase bank website. In debug builds, I'm getting: ASSERTION FAILED: !ec (/Volumes/work/WebKit/Source/WebCore/dom/Range.cpp:86 WebCore::Range::Range(WTF::PassRefPtr<WebCore::Document>, WTF::PassRefPtr<WebCore::Node>, int, WTF::PassRefPtr<WebCore::Node>, int)) Copying a few people who have modified Range.cpp recently just in case they have a better idea about this.

Actually, the original patch was written by me. Justin just committed it. I should be able to post a patch tonight or within the next couple of days. 333425 7 78758 rniwa 2011-01-12 16:55:20 -0800 Created attachment 78758 fixes the bug 333428 8 rniwa 2011-01-12 16:57:45 -0800 (In reply to comment #7) > Created an attachment (id=78758) [details] > fixes the bug It turned out that the root cause of this bug was present before r69831 but VisiblePosition was more "forgiving" for historical reasons (e.g. legacy editing position). 333432 9 78758 eric 2011-01-12 17:02:47 -0800 Comment on attachment 78758 fixes the bug View in context: https://bugs.webkit.org/attachment.cgi?id=78758&action=review > Source/WebCore/rendering/RenderTextControl.cpp:311 > + if (offset <= start && start <= offset + length) { > + if (node->isTextNode()) { > + } else { > + } > + if (offset <= end && end <= offset + length) { > + end -= offset; > + endNode = node->parentNode(); > + } > + break; > + } These two blocks are basically identical.

Sorry I read those both as 'abc', now I understand why the complexity is needed. 333473 14 rniwa 2011-01-12 18:20:30 -0800 (In reply to comment #13) > (In reply to comment #12) > > Maybe I should do: > > > > if (name == 'textarea') > > expected = shouldChangeSelection ?
