           Summary: document.createTouch does not throw anything
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

According to the documentation of the document.createTouch API at http://developer.apple.com/library/safari/#documentation/UserExperience/Reference/DocumentAdditionsReference/DocumentAdditions/DocumentAdditions.html the document.createTouch and document.createTouchList APIs can throw a DOMException. However it is unclear after experimenting with the current iOS implementation how and when these APIs throw.

We should verify any cases that the function should throw and implement them. See FIXME in implementation of createTouch in Document.cpp.
