452595 - When inserting a numbered list into any rich-text control, the number is always exposed as 0.

Status: RESOLVED DUPLICATE of bug 557795

(Core :: Disability Access APIs, defect)

Description

[Marco Zehe (:MarcoZ)]

STR:
1. Start a current Shredder (Thunderbird 3) build.
2. Compose a new message.
3. Make sure under Tools/Encoding, Rich-Text (HTML) or "Both Rich-.Text and Plain Text" is selected.
4. Choose Format/List Style/Numbered.

Result: The first list item is created. Visually it is preceeded by the number "1.". However, when looking at the hierarchy using AccProbe, I see:

- List
- - ListItem[1]
- - - StaticText with a name of "0"
- - - Text with nothing or the entered text.

5. Type in something, and press ENTER. A new item is created, preceeded by "2.".

Result: In accessibility, another list item was appended, but its static text child is also given a name of "0". Also, the previous one did not get updated. In effect, a11y shows 2 numbered list items whose number is 0.

Is this a regression? 

Comment 2

Correction to the above, this also reproduces for me in Firefox using the WordPress Rich-Text editor which is based on TinyMCE. The steps are roughly the same:
1. Start a new post.
2. Insert an ordered list.

Observe that the "label" element that preceeds the actual text is always "0". Question: Why is it a label here and not statictext?
