As mentionned here (Workflow custom props update ) any activiti process property can be set from task/process activiti listener and read by WorkflowService API as soon as the property is defined as a process (start task) property.
But once the process is completed, these variables are not returned anymore by WorkflowService API.
Only variables set at process startup are returned. Why ?
All variables are found in 'act_hi_detail' activiti table. How to access these data from WorkflowService ?
