@bramd are you still able to reproduce this issue?

@Adriani90 Not exactly, but there are still issues editing footers.

After inserting a footer and editing it, I get the following:

ERROR - eventHandler.executeEvent (23:17:42.940):
error executing event: caret on <NVDAObjects.Dynamic_SymphonyParagraphSymphonyTextEditableTextWithAutoSelectDetectionIAccessible object at 0x0640EA30> with extra args of {}
Traceback (most recent call last):

  File "NVDAObjects\IAccessible\__init__.pyc", line 180, in _getCaretOffset
RuntimeError: Retrieving caret offset failed

Caret movement isn't detected and braille doesn't update.

I don't get any error when alt+tabbing, however I did get an error in the log when typing into the footer to begin with:

I haven't currently got a Braille display connected, but NVDA reads everything as it should in the footer (letters as I arrow, words or the whole thing with say all / read current line etc).

In OpenOffice, I don't get an error like that, but when typing I get the following warning (this was when pressing space after a word, I had NVDA set to echo typed words but not characters) which may be related to why this only happened at the end of words):
