Hi all,
Sorry for not being more specific last time. I still can't get the Ajax parts
to work, but keep getting NullPointerExceptions. I am using Cocoon 2.2 and
maybe this is a known problem. More probable is that I have missed some detail.
The exception is thrown both when the form is validated through ajax (when
clicking submit) and when a on-value-changed action is triggered. The
stacktrace is found below.
Any help is highly appreciated!
Thanks,
Marcus

Subject: CForms/Ajax
Hi,
I am trying to learn cforms, and I get more and more impressed every day. I
can't, however, get the ajax part to work properly. Is there a simple example
out there that shows how it should be done? I find the provided samples quite
"messy" (sorry for the expression) when it comes to this. Or maybe someone
could explain what kind of pipelines I need to set up.
Thanks,
Marcus
