617896 - IAccessible2 - Invalid document hierarchy (IAccessibleHypertext).

Status: RESOLVED INCOMPLETE

(Core :: Disability Access APIs, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 (.NET CLR 3.5.30729)

The implementation guide states:

Under the "The Caret" section it's written:
"Furthermore, the document hierarchy is not valid until the client can:

1. Start from the object with focus, and by recursively using the
AccessibleChildren function provided by MSAA, find the object that
contains
the caret;
2. start from the object with focus, and by recursively using the
IAccessibleHypertext interface, find the object that contains the caret;
and"

In FF using only approach "2", it's impossible when there is text in a
cell in a table in a document. The table I tried is seen on the right side of
the document at http://ckeditor.com/demo. According to the implementation
guide, that renders the document hierarchy invalid.

Reproducible: Always

It's major issue for AT to deal with tables in editable area. Personally I don't like to turn tables into hypertext accessibles and I prefer to change IA2 to provide a correct way (more performant, more robust). Let's plan in for fx5.

Like using the proposed accessibleWithCaret() method?
