The message "javax.jcr.AccessDeniedException: cannot read item
cd098ecf-22a8-4a47-b345-e37db309e626" suggests that this is most
likely a permissions issue. The user (group) used to write the form
data to the repository (probably 'sitewriter') needs the have
sufficient read and write privileges on certain security domains. It
appears that this is not documented, sorry for that.
So first we need to figure out which privileges on which domains the
sitewriters group need to have. I'll look into this when I find some
time. In the meantime if anyone can look this up easily in their
project please chime in.
Once we figure that out I will update the documentation with that information.
Thanks for your feedback,
Niels
