This is unbeliveable. Only with Plone, one can spend 8 hours to make 
patch, make unit tests for it and test the patch just to notice he/she has 
been patching the wrong part of the code.

Looks like I shot myself to foot with Plone again. session_save_form.py 
was refered by session_restore_value.py, in comment: "Return field value 
previously stored on session by session_save_form". 
session_restore_value.py was referred by field.pt: "value 
python:widget.postback and request.get(fieldName, 
here.session_restore_value(fieldName, value)) or value;". Logical 
decision: session_save_form handles postback data saving.

However, looks like session_save_form doesn't actually handle saving 
postback data. session_save_form was only referred by add_reference.py.

I still don't know where the actual postback data is saved. My next lucky 
guess is content_edit_impl.py.

Forget this patch. I'll rework it. Before I am going to look this matter 
further, either my forehead or wall next to me will break. You can contact
