            Bug ID: 144086
           Summary: Custom List Styles associated with Paragraph Styles
                    have no effect.
           Product: LibreOffice
           Version: 7.2.0.4 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: ronblanshi at gmail.com

Description:
f one creates or edits a paragraph style and opens the "Outline & Numbering"
tab and selects a valid outline level from the drop-down list and does the same
in the "Numbering Style" drop-down list, then saves the paragraph style such
that there is a paragraph style associated to at least two or more levels of a
List Style, then uses one of those paragraph styles in a document and changes
either the outline level or the paragraph style, the respective associated
paragraph style or outline level does not change also as it does with styles
associated with Chapter Numbering outline levels.  This must be done manually.

Steps to Reproduce:
1. Create or edit a paragraph style.
2. Open the "Outline & Numbering" tab, select a valid outline level from the
drop-down list.
3. Select a valid List Style from the "Numbering Style" drop-down list.
4. Save the paragraph style such that there is a paragraph style associated to
at least two or more levels of a List Style.
5. Change either the outline level or the paragraph style.

Actual Results:
1, Selecting the paragraph style does not change the outline level to that
associated with the paragraph style.
2. Changing the outline level changes the paragraph number style, but the
paragraph style does not change to align to the paragraph style associated with
that outline level and that List Style.

Expected Results:
For Chapter Numbering:

1. If one selects the paragraph style, the outline level automatically changes
to match that style but that is not what happens when a custom List Style is
used, outline level stays the same.
2. If one changes the outline level, the paragraph style also changes to align
to the paragraph style associated with that outline level.

That is the way that it should work with Custom List Styles also.


Reproducible: Always


User Profile Reset: No



Additional Info:
Version: 6.1.5.2
Build ID: 1:6.1.5-3+deb10u7
CPU threads: 2; OS: Linux 4.19; UI render: default; VCL: gtk3_kde5;

This problem was duplicated exactly in Version 7.2.0.4 on a Windows 10 machine
but I am sending this from my Linux machine.

More Comments:

With Chapter Numbering, at each outline level, there is a drop-down box where a
single paragraph style may be chosen.  No such option exists when defining the
outline levels for Custom List Styles.  On the other hand, when defining
paragraph styles, one can select both an outline level and a List Style for
each paragraph style, permitting more than one paragraphs styles for each level
of the List Style, which could cause problems in the program.  Although there
are several ways to resolve this confusion I will mention the one I favor:

1. For each outline level of a Custom List Style, permit the selection of one
or more paragraph styles, similar to the method used in Chapter Numbering but
with multiple assignments possible in some order either selected by the user or
assigned chronologically wherein the top assignment in the list would represent
the default.
2.1. I would suggest the format to be a rolling list of all Paragraph Styles
currently assigned to that List Style Level with the default at the top.  A
right click on any item in that list provides a drop-down list with three
choices.
2.1.1. Add a Paragraph Style to the list which opens a blank position at the
top of the list with a drop-down list of all Paragraph Styles below the blank
position.
2.1.2. Assign the selected Paragraph Style as the new default Paragraph Style
for that List Style Level.
2.1.3. Unassign the selected Paragraph Style from that List Style Level.
2.2   The program should use the last Paragraph Style used at that point in the
document as the next Paragraph Style for that List Style Level or,
2.2.1. If no style has yet been used at that List Style Level, then the default
style would be used.  As this situation is the only time a default is required,
the order of the list is superfluous beyond the assignment of the default
Paragraph Style at that List Style Level.
2.2.2. If no paragraph style is assigned to the List Style Level, simply use
the Paragraph Style of the preceding paragraph as is already implemented, but
do not require a Paragraph Style to be selected for each or for any of the
Custom List Style outline levels.
2.3. Moreover, if one would select an outline level and a List Style for a
Paragraph Style as is currently possible in the “Outline & Numbering” tab, this
would simply add that relationship to the list of Paragraph Styles for that
List Style Level and make that List Style Level a required numbering style for
that Paragraph Style or, leaving those selections as “body text” and “none”
would not require the Paragraph Style to be associated with a numbering style
unless manually selected from the list of “List Styles” or if it was previously
used in a List Style Outline in the document which would cause the program to
default to using that Paragraph Style in that outline stream as previously
noted above.
3. I can see great usefulness in being able to associate an outline level and
List Style pair to more than one paragraph style, but only if it works the way
I describe.  Moreover, the way it works now, there is really no reason nor
effect in associating a paragraph style with a List Style as the association
must be handled manually anyway.
4. I consider this a bug as it severely limits the usefulness of List Styles
and there seems to be no rational reason to associate a paragraph style to an
outline level or a list style in this current state.
5. Moreover, I have noticed that if one assigns a Paragraph Style to a Chapter
Number Paragraph Style and then assign a List Style to that paragraph, it is
impossible to get the paragraph to go back to Correct Numbering style without
using the go-back button or, placing a new paragraph above it and apply the
correct paragraph style to that paragraph then delete forward from the end of
that paragraph and hit return which forces the paragraph style and numbering
style on that paragraph.  Hence, I would also suggest including the Chapter
Numbering style in the List Style list as a default which cannot be deleted
from the list.
