Description Ulrich Windl 2017-10-18 06:47:37 UTC
I have a numbered list where the first item had a "restart numbering" option set.

Steps to Reproduce:
I moved the first item to the head of another numbered list (via cut & paste), so the old first item in the second list became the second item, but stil having number "1". So I selected "continue numbering" via right mouse button for the second item, just to find out that the number was still "1"!
Looking again I realized that "restart numbering" was still in effect. I had to deselect it, then numbering was as intended.

Actual Results:  
OK after using the fix described above.

Expected Results:
Correct result with fewer steps needed to fix.

Reproducible: Didn't try

User Profile Reset: No

Additional Info:
So these are the fixes to consider:
1) Do not copy the "restart numbering" attribute when copying list items. Or allow not pasting the attribute.
2) Make "continue numbering" and "restart numbering" mutually exclusive.
3) Both of the above.

I confirm the behaviour you describe, but for me this behaviour is logical. So for me it isn't a bug. And I can think of a lot of situations, where it is helpful, that the "restart numbering" remains if you copy the item.

So I change it to enhancement, because everything works as it should work. And my proposal is to close this bug as NOTABUG.

On "NOTABUG": The original issue was ``"Resume numbering" does not cancel "restart numbering" on enumerated list''

Please read again!

Let's set to NEW then.
Comment 5 Thomas Lendo 2019-09-19 20:00:39 UTC
I revert the summary to it's original state because I think the bug opener was misunderstood. It's not a pasting problem. I'll test this when I'm on a PC or laptop.

Ulrich, please test again with a new document in LibreOffice 6.3 or 6.4.
Comment 6 Thomas Lendo 2019-09-22 18:36:10 UTC
I can't reproduce because if I insert parts of another list (direct formatted lists or list with styles formatting) the original list numbering isn't pasted. Therefore I can't resume nor deselect a numbering restart.

Ulrich, please retest.

I think I agree that a fairly logical work flow when switching from one list to another (called "add to list" instead of "continue numbering") would be to clear the "restart numbering" property at the same time.

   if ( pRule )
+      if( rWrtSh.IsNumRuleStart(/*pPam=nullptr*/)
+          && rWrtSh.GetNumRuleAtCurrCursorPos() != pRule)
+      {
+          rWrtSh.SetNumRuleStart(false, /*pPam=*/rWrtSh.GetCursor());
+      }

       rWrtSh.SetCurNumRule( *pRule, false, sContinuedListId );

[If the selection spans multiple numbering rules, the one at the cursor might be identical to the one being joined. So this isn't going to be consistent in every scenario, but it would cover the normal case - which should be good enough.]

But this isn't good enough because IsNumRuleStart/SetNumRuleStart only affects pPaM->GetPoint() (the end of the selection), so instead we need to somehow step through the selection and check each para if it isNumRuleStart for a different numRule.

113213 _removeNumberingWhileAddingToList.patch: abandoned

Whether cancelling re-numbering while merging is desired will be completely dependent on the content, which a machine won't be able to determine. It would not be appreciated by automation.

If you have already shot yourself in the foot by restarting numbering a list, and now you want to shot yourself in the other foot by merging it with another list, I guess you shouldn't be surprised that you feel pain.

The patch seems fine to me, but Writer is so incredibly complex and I couldn't find the functions that I would have expected to handle basic things like walking through paragraphs. So perhaps the code is rather poor, since I felt I was re-inventing some basic things.
Comment 13 Dieter 2022-05-04 09:43:08 UTC
Since LO 7.2 we have "Add to List" instead of "Continue Previous Numbering" and we also have a documentation about it [1] and also a documentation about "Restart numbering"[2]

Ulrich, taking into account this improvments, could you please retest? (I must admit, I couldn't understand comment 9 - comment 12)
