Hi

(jbp-2.0.1 is used)

i defined the action value of a form like:

<form method='POST' action='<portlet:renderURL><portlet:param name="op" value="update"/></portlet:renderURL>'......

When the forum is submit, i hope the render doView() method will be called.
However, It seems that this assumption is wrong. I got following exception:

Who can give me some indication?

thanks in advance!
