Custom WorkItemHandler gets null ksession
stevenhu Feb 10, 2015 2:44 PMI have a process with 4 custom work items (Highlighted in red box), shown in the following:
When I started and executed the process, I found the custom workitem [GetProfile] and [GetPomProfile] got a correct ksession instance, but other two [ExecuteCommand] and [ValidateTxn] got a NULL kession. (AbstractWorkItemHandler is the parent class of all custom work item handlers). Can anyone tell me why the following custom work item handler is getting null kession input?
the kie deployment descriptor on work item handlers:
<work-item-handler> <resolver>mvel</resolver> <identifier>new com.pti.fsc.wfe.workitem.handler.FscQueryProfileParameterWorkItemHandler(ksession)</identifier> <parameters /> <name>GetProfile</name> </work-item-handler> <work-item-handler> <resolver>mvel</resolver> <identifier>new com.pti.fsc.wfe.workitem.handler.FscQueryProfileParameterWorkItemHandler(ksession)</identifier> <parameters /> <name>GetPomProfile</name> </work-item-handler> <work-item-handler> <resolver>mvel</resolver> <identifier>new com.pti.fsc.wfe.workitem.handler.FscExecuteWorkItemHandler(ksession)</identifier> <parameters /> <name>ExecuteCommand</name> </work-item-handler> <work-item-handler> <resolver>mvel</resolver> <identifier>new com.pti.fsc.wfe.workitem.handler.FscValidateTxnWorkItemHandler(ksession)</identifier> <parameters /> <name>ValidateTxn</name> </work-item-handler>
the log is pasted here:
