Hi Tobias,
To create a TextRange object, you can use only the body, button, and textArea
objects and
an input object with one of the following types: button, hidden, password,
reset, submit, or text.
The isTextEdit property can be used to avoid the exception.
You should use qx.bom.Range.get instead.
Regards,
Romeo

Betreff: [qooxdoo-devel] ScriptError with IE 10 in Focus.js
Hi,
recently, we came across a script-error when creating several buttons with IE10
on Windows 8 machines where the Focus-Handler fails to call "createTextrange".
The Project uses 2.0.1 but the code seems unchanged from 2.1.1:
try {
// focus element before set cursor position
element.focus();
// Fixed cursor position issue with IE, only when nothing is selected.
// See [BUG #3519] for details.
var selection = qx.bom.Selection.get(element);
if (selection.length == 0) {
var textRange = element.createTextRange();
textRange.moveStart('character', element.value.length);
textRange.collapse();
textRange.select();
}
} catch(ex) {};
The element is obviously valid, otherwise it would have crashed at
element.focus(). Exact message is:
Caught exception occurred : Object doesn't support property or method
'createTextRange'
Sadly I was not able to setup a simple testcase for that - it happens during
some large DOM-update as a forum window gets created and shown. Same code
worked fine with IE versions before. This message gets only posted to console
if "break on error" is enabled, otherwise the IE tab will crash.
Is there any workaround available for that or do we have to revise the whole
flow of window creation because of that?
Thanks in advance,
Tobias
