Re: Flash scope still broken? (Mojarra 2.3m04)

Hi Lenny,

Thanks for letting us know.

The Flash has always been rather problematic in the past, and the
implementation code is particularly problematic.

On top of that, as you might have noticed, the resources dedicated to JSF
are not entirely optimal at the moment. Since you cannot reproduce this
either, I'm afraid the chances of fixing anything for this are rather slim.
I simply wouldn't know where to begin fixing :(

I have to say that I've occasionally seen this error in production too, but
that's for an app that's actually using The Flash.

If you may encounter anything in the future that could help us nail this
down don't hesitate to post about it again. Thanks!

Kind regards,
Arjan Tijms
