I am trying to use the value of a variable to determine the assignment of a task. According to the documentation the syntax is as follows: <assignment expression='previous --> group(hierarchy) --> member(boss)' /> In my usage my syntax looks like: <assignment expression="variable(WORCostCentre) --> group(Department)"></assignment> WORCostCentre is a variable from a previous task which has a String value equal to the name of a Group with a group-type of Department. I am using the environment: Environment: Eclipse 3.3, EMF: 2.3.1, GEF: 3.3.1, DTP: 1.5, WTP: 2.0, jbpm-jpdl-designer-3.1.0.sp1 When I complete the task and it follows the transition to the block with the above mentioned assignment expression I get a ExpressionAssignmentException and it states the user does not exist. According to the documentation the variable tag can be used for User or Group objects. Is my method incorrect or is this a bug?
