To be a little more clear, I have tried to use <task name="MyTask"> | <assignment class="com.myapp.MyAssignmentHandler" expression="user(me)"/> | ... | and I have tried to use swimlanes and do | <swimlane name="SwimlaneMe"> | <assignment class="com.myapp.MyAssignmentHandler" expression="user(me)"/> | </swimlane> | | ... | | <task name="MyTask" swimlane="SwimlaneMe"> | | ... | | But both times the app still calls to ExpressionAssignmentHandler to calculate user(me).
