I have the same problem, using Jbpm 3.2.2. If I use the expression: <assignment expression="group(MyGroup) --> member(Team Leader)"></assignment> It works fine, and is assigned to the actor who is in the group "MyGroup", and has the role in that group of "Team Leader". But, if I use: <assignment expression="variable(group) --> member(Team Leader)"></assignment> It says the user "MyGroup" cannot be found in user db. But the variable "group" I used which has the value "MyGroup", is not a user, it's a group. And the documentation at http://docs.jboss.com/jbpm/v3.2/userguide/html/taskmanagement.html#assign... does state: anonymous wrote : "variable(variable-name) means the user or group is taken from the specified variable instance. The variable instance can contain a java.lang.String, in which case that user or group is fetched from the identity component. Or the variable instance contains a User or Group object." Anyone know what we are doing wrong? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4094094#...
