Sorry for another 2.1.10 upgrade question. I've been able to tackle

The first time a session calls any continuation an exception occurs

Hmm, I don't know if this will be any help, but maybe...
Certainly the NPE results from the FOM_Cocoon object having a null
value for its currentCall instance variable. A few months ago I had to
add some AJAX features to a previously non-AJAX-using application built
on Cocoon 2.1.8, and I was getting a similar failure, but mine was in
jsGet_continuation(). I can't remember why currentCall was null in my
case, unfortunately I didn't document this incident and now I don't
recall the details... but I'm pretty sure I remember being certain that
this was normal and not caused by anything I was doing wrong. I made a
local fix in FOM_Cocoon to have jsGet_continuation() return null if
currentCall was null.
Now, you can't just do the same thing here... :-/ But maybe it helps
you to know that somebody else had a situation where the cocoon
object's currentCall was null and that it was (presumably) legitimate.
