Reopening completed workflow human task

Usecase: Sometimes we may come across a situation where we wanted to re-open the completed workflow human task.

Implementation steps:

• Capture the token and taskid attributes of completed human task. You can get these task attributes from 'initiateTaskResponseMessage'  outputVariable which will be created in INVOKE activity of human task service

• Drag and drop database adapter after human task RECEIVE activity and execute delete operation from orabpel.wftask and orabpel.wfroutingslip where taskid = 'Already captured Taskid'
• Drag and drop invoke activity and link it to TaskServcie partnerlink service and select 'reinitiate Task' operation

• Drag an Assign activity before last INVOKE and assign previously stored Taskid, token and 'ASSIGNED'  literal value to Taskid,token and state fields of  Invoke_1_reinitiateTask_InputVariable respectively
• Compile and deploy
