急！！swimlane ,group and user

[linjunzhang]

I am working with jbpm starters kit. I have created a workflow with few task nodes in it. I created swimlanes with expression as group(groupname) and associated it with a task in a task node.

I inserted a record in JBPM_ID_GROUP table with the groupname which i am using in my swimlane. Also, i do have few users who belong to this group (through JBPM_ID_MEMBERSHIP table).

Now, when i start the process and when control comes to that task, i am getting a message saying "A new task has been assigned to 'null'". And i could not see that task in any of the users who belong to that group. The task is not appearing in any of the users login. JBPM does not support such kind of functionality? Does group expression in swimlanes does not work at all? Or am i missing anything here? Can anyone let me know, whether jBPM does support such kind of functionality or even is there any information on how to extend group features from jBPM?

However, instead of using group(groupname) expression, if i use user(xyz), it does work properly. I am able to see the task in the tasklist if i log in as user xyz. Problem seems to be only with group expressions.

Any help would be appreciated

jbpm主要是对流程扭转的控制，对表单数据的控制也有，单功能不强，本人采用jbpm和润乾报表进行结合，jbpm只对扭成扭转进行控制，润乾报表对数据控制。这样就实现了流程挂接报表（统计报表和填报表表）在企业内部进行扭转，实现企业流程的信息化。
