245635 - list-style-type: decimal produces all zeros when used in an XML document with display: list-item

Status: RESOLVED DUPLICATE of bug 4522

(Core :: CSS Parsing and Computation, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a1) Gecko/20040520

I am attempting to create a numbered list with CSS in an XML document. My
apologes in advance if this bug has already been reported. In the reference URL
above, the list should be numbered, instead of all zeros. I get a numbered list
when ran in Opera and IE as I expect to (yes, do hold back the nausea induced by
that reference -- that's about all I get that I expect to in that browser).

The CSS in the document looks somthing like this:

    directions {
        display: block;
        font-size: 130%;
        padding: 5px;
        list-style-type: decimal;
    }
    direction {
        display: list-item;
        margin-left: 30px;
    }

I've tried a number of different approaches including counters, which I did see
a long-standing bug already filed for. That leaves me to assume a bug in Mozilla.

Looks a lot like like bug 4522 (marking dependent for now, since the list-item
parent is in fact display:block here...)

Richard, could you attach the testcase to the bug (attach the CSS first, point
the XML at it, then attach the XML) using
http://bugzilla.mozilla.org/attachment.cgi?bugid=245635&action=enter ?

That way we can be sure the testcase won't disappear...

Actually, I guess attach the background image first, then point the CSS to that,
then attach the CSS, etc (the background image is causing a performance issue,
filed as bug 245899).

Should this bug also depend on bug 3247?

Comment 5

[Boris Zbarsky [:bzbarsky]]

Not unless our list impl uses counters (which it currently does not).

Attachment: self contained testcase

You can actually create a self contained XML testcase where the style is
embedded in an XHTML style element, like here. This is a lot smaller testcase
than the original.

The problem seems to be that FrameStartsCounterScope() returns false when called
on blocks that don't have a -moz-counter-reset setting (see
http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/layout/html/document/src/html.css&rev=3.174&mark=311,319#304
for where we set it on HTML lists).  If FrameStartsCounterScope() returns false,
RenumberLists() bails out.
