Re: [g-a-devel] AT-SPI table interface problems

[Peter Parente <pparent us ibm com>]

Hi Bill,

I've created a bug report about the
table problems I posted about earlier (http://bugzilla.gnome.org/show_bug.cgi?id=319088).
I attached a simple test case to the report that reproduces the problems
in the character map application.

Hi Pete

These sound like bugs.  Of course, operator error is another 
possibility, but in any case we can't determine what to do without bug
reports, test cases, etc.

FWIW, I don't see these sorts of problems with at-poke, and gnopernicus
has not encountered them, so it's possible that you have inadvertantly
wandered into unexplored regions of the gtk+ treeview implementation.
