Offset page displays a zero.

When I add a negative offset (-1) to the page number field, the page that was offset displays a zero instead of displaying nothing.

In previous Libreoffice versions, it would never have displayed a zero on the offset pages.

Comment 6 Matthew Francis 2015-01-12 09:56:02 UTC
The behaviour seems to have changed as of the below commit. Unfortunately this is required for compatibility with .doc/.docx, so while it may be inconvenient that it doesn't work like it used to, I don't see that there's a way to put it back like before - 0 is now a valid page number, and it will remain that way.

-> Setting status to RESOLVED WONTFIX

    fdo#44689: fix for specific case of page restart-value 0
    This bug fix is for roundtripping a DOCX that has
    a specific 'start value' for the page numbers.
    In most cases LO imports it ok.
    However - until now - Word allowed you to start page number
    from 0, while LO only allowed starting page numbers from 1.
    This was because the 'start value' was stored in an 'unsigned int',
    and the value '0' was used to mark 'there is no start value'.
    This patch changes the way the 'start value' is stored
    from 'unsigned int' to 'optional unsigned int'.
    This way - if there is no value applied - the variable will hold NULL.
    However - if a value is set - it can be 0 or more.
    This meant also tweaking all the places that used to get this value,
    so that now they handle an 'optional uint', instead of a 'uint'.
