Dear Mark Stenglein,

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
https://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:

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

Warm Regards,
QA Team

[Libreoffice-bugs] [Bug 104211] Fails to save previous state for undo when I `Import MathML from clipboard`

--- Comment #4 from Regina Henschel  ---
Created attachment 130127
  --> https://bugs.documentfoundation.org/attachment.cgi?id=130127=edit
content is Unsinn

The error is not part of the new feature "Import MathML from Clipboard" but
exists in other scenarios too.

Download the attachment Unsinn.mml
Have a formula in the Command Window.
Goto Tools > Import Formula.
Select the file "Unsinn.mml" and set the filter explicitly to "Math ML 2.0
(*.mml)".
Open.

Notice, that the current formula is erased in this scenario too and here too no
undo action was created.

The error is not, that there is no undo. But the error is, that the command
window is erased. If the clipboard is not convertible, then nothing should
happen, especially the command window should not be changed at all. That works,
if the clipboard is simple text, which do not look like XML, for example. So I
think, it is indeed a bug.

I have no immediate solution and currently not enough time beside my daily job,
therefore I will not assign the bug to me.

@Mark Stenglein: For you current task, you should consider to open a separate
formula document and first test, if the import works, before you actually
insert it in your formula.

Import works, if you have got a valid MathML fragment, including the namespace
attribute with value "http://www.w3.org/1998/Math/MathML;. Then it is inserted
at cursor position and you get an undo.

Hmm, not sure about this...

Yes, the control-Z step backward does not apply consistently to actions with an
OLE object. But, the Math module Undo/Redo controls retain change details on
reopening the OLE.

As is I can not reproduce with LO 5.2.3.3 or 5.3.0beta1 using STR here.

And I was able to import actual MathML fro clipboard, or import a MathML 2.0
formula, and then edit and revert (multiple Undo/Redo) within the Writer
document with the OLE Math module opened.

And of course considerable utility with complex formulas to work outside of
Writer, composing the formula(s) first in Math module and then inserting the
objects from file (.odf or .mml) into the manuscript.

After thinking about it for a few minutes, I feel like it might be simple
enough to fix by just running whatever code is run when you click out of the
formula that saves the formula into the Writer document.

I'm not familiar with the LibreOffice code base so I can't get too specific,
but I feel like if this were run before the `Import MathML from clipboard` it
would give the History log a checkpoint to return to in case that function has
unexpected behavior for the user.

I'm a college student so I don't have a _huge_ amount of time to play with to
dive into the code base, but I might be able to look specifically at it
soon...ish.
