In default.py, onCaretMoved checks to see if the object firing the caret-moved
event exposes STATE_SHOWING. If STATE_SHOWING is absent, then that event is
ignored because we only want to (potentially) present the new caret location if
the user is in that text object. And if the thing isn't SHOWING, presumably the
user is not in that text object.

The workaround is the addition of presentEventFromNonShowingObject, which
allows scripts to tell the default script that even though something isn't
SHOWING, the caret moved event might still be worthy of presentation. The
default implementation of presentEventFromNonShowingObject returns False. The
LO script's implementation unconditionally returns True.

As for what I think might be causing this on the LO side of things, my guess
would be either the logic which determines if a paragraph is SHOWING and/or the
logic which updates (via a state-changed accessibility event) the SHOWING state
(e.g. when something is scrolled into or out of view).

But you could reproduce it in 2017 alongside Chrys and Joanmarie, so this
should stay NEW. Otherwise we risk this being closed as INSUFFICIENTDATA.

IMHO, it's relevant because I'm not able to reproduce the issue without a
script to reproduce it.

I would like the help of Joanie for this issue because with have hacked Orca to
figure out this but this issue is not fixed yet.

@Joanie: Could you write a Python script to help us reproducing this ?

Best regards,
Alex.

--- Comment #11 from QA Administrators  ---
** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:
https://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

Is 105487 caused by the same problem? The symptoms of both seem quite similar.

Ok, I've added a targeted hack-around in Orca which should only impact
LibreOffice document content. Hopefully this will make it possible for Hypra to
stop reverting an important Orca-wide fix which impacts all applications.

It only means that the bug has an better importance. The LibreOffice devs
decide on which bugs they want to work on so this bug could stay in this state
for a very long time but I hope someone could work on it.

Best regards.

Yeah I think we can easily nudge a11y issues up a bit.

If it has been confirmed independently, it should be set to NEW (done).

I only used down arrow.

Are you using only down arrow to move to the buggy line? Sometimes, LibreOffice
reads the buggy line but it's another line that is not read.

To be sure to reproduce the issue you need to know that Orca should speak on
all the line with the text content or "blank" on empty lines.

If you don't reproduce the issue the first time move to beginning of the
document and press down arrow again until to find a unread line.

I've reproduced on Debian 8.9, Sid and Ubuntu 17.10 daily build.

The bug has been confirmed by one user and the Orca developper :
- https://mail.gnome.org/archives/orca-list/2017-July/msg00025.html
- https://mail.gnome.org/archives/orca-list/2017-July/msg00034.html

Best regards.
