Re: [orca-list] Why Orca navigation algorithms are not supporting Clickable embedded Adobe flash player objects?

[Mike Gorse <mgorse alum wpi edu>]

Yeah, it looks liks there is a caching issue somwwhere. I can mostly work 
around it by telling AT-SPI not to cache children for Firefox. Ie; 
putting
app.setCacheMask(pyatspi.cache.ALL ^ pyatspi.cache.CHILDREN)
into the Gecko script's __init__ function.

So either Gecko is not always sending children-changed events when 
children are added or go away, or AT-SPI is somehow failing to pass them 
on / notice them. AT-SPI 2 caches several things 
(names/roles/states/children/parents) that AT-SPI 1 didn't to the same 
extent, to compensate for D-Bus being slow, so it is affected by 
applications not sending events in a way that AT-SPI 1 was not.

I still see the issue sometimes even with that change, though (for 
instance, by going to google.com and tabbing to "privacy"), so I suspect 
there is more than one issue.
