Hi Odelya,
Did you find out any solution for this problem?
I have the same issue, but I want to implement this mechanism in Liferay portal, but I don't know exactly how can I handle JSF page to show users when they are faceing with a human task in my liferay portlet?
I know that there is a forms.xml file that store node and related forms that jbpm-console can display them to users but I didn't find a solution to i can implement in my application.
any idea ?
