           Summary: WebView - (void)setSelectedDOMRange fails in many
                    circumstances
           Product: WebKit
           Version: 419.x
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: HTML Editing
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: robburns1 at mac.com


When trying to insert a new element at the selectedDOMRange and that
selectedDOMRange is collapsed the WebView will not accept a setSelectedDOMRange
under several circumstances.

I've loaded content as both text/html and application/xml+xhtml.
I've tried inserting an empty textnode; a textnode with a single
zero-width-space; a textnode with a single space (see bug 10881); and a
textnode with several zero-width-spaces.

I've tried [webView replaceSelectionWithNode:],  [selectedDOMRange
insertNode:], and a few others. I've tried normalizing (which seemed to have no
effect at all). I'v tried selecting the inserted element with offset (0,0) and
offset (0,1).

I've tried inline and block elements.
When working with application/xhtml+xml I've tried (DOMDocument createElement:]
and(DOMDocument createElementNS:] .

All of these attempts have had the same results. The log shows a successful
change of the ivar selectedRange, but when invoking setSelectedDOMRange on the
webview it doesn't take.

Setting the selected DOMRange on Exiting elements work fine, but on the
elements I create it fails. Without altering the selectedDOMRange to be inside
newElement there's no way for the user to navigate with the keyboard into the
element (bug report forthcoming).

Below is a code fragment that should help reproduce the bug and provide an
illustration of the problem.


                if ([selectedRange collapsed]) {

//                      textPlaceholder = [theDOMDocument createTextNode:@""];
                        textPlaceholder = [theDOMDocument createTextNode:
                                [NSString stringWithFormat:@"%c%c%c",
                                        8203, 8203, 8203]];

                        [newElement appendChild:textPlaceholder];
                        [selectedRange insertNode:newElement];

                        NSLog(@"selectedRange is: %@", selectedRange);
                        NSLog(@"the prior selected range is: %@", [webView
selectedDOMRange]);
                        NSLog(@"newElement is %@", newElement);

                        [selectedRange setStart:textPlaceholder :1];
                        [selectedRange setEnd:textPlaceholder :2];

//                      [selectedRange setStart:newElement :0];
//                      [selectedRange setEnd:newElement :1];

//                      [selectedRange collapse:YES];

                        [webView setSelectedDOMRange:selectedRange
affinity:NSSelectionAffinityDownstream];

                        NSLog(@"new selected range is: %@", selectedRange);

                                NSLog(@"the selected range is: %@", [webView
selectedDOMRange]);
                        [webView display];

                } else {

                        aFragment = [selectedRange cloneContents];
                        NSLog(@"aFragment is %@", [aFragment textContent]);
                        [newElement appendChild:aFragment];
                        // [selectedRange surroundContents:newElement];
                        [webView replaceSelectionWithNode:newElement];
                }
