Keith,
Thanks for this tip.
I haven't experienced this behavior (svn Myfaces, facelets 1.0,
firefox 1.0.7, client-side state saving) even though I don't have this
line of code.
Can you explain that the problem is and why saveSerializedView() solves it?
I'd like to know if I'm going to be hit by it at some future point.
Also, some of the other myfaces committers were talking about creating
a download component, so it'd be good to know when we need to include
this code.
