I'm implementing an asynchronous task. To do that I don't call the WorkItemManager.completeWorkItem method in my bpmn.
I have various parameters passed trough each workItem and they are serialized using JPA.
At some point I need to restart my workflow by reloading the session and calling the completeWorkItem method with the workItem id (line 06).
For the moment before making my workItem asynchronous, I store the parameter map in a BLOB in db.
At the time of restarting my workflow I load the BLOB content (line 04) and pass it as a result to the completeWorkItem method.
As the workItem parameters are stored by JBPM, I would like to get rid of my BLOB because it makes my migrations sometimes difficult.
How can I avoid storing and retrieving the parameters by myself?
To be more specific, here is a code snippet for the workflow continuation:
final SerializedWorkflow sw = this.serializedWorkflowRepository.findOne(serializedWorkflow.getId());
StatefulKnowledgeSession ksession = this.knowlegBaseFactory.loadStatefulKSession(sw);
final Map<String, Object> params = (Map<String, Object>) sw.getParamsAsObject();
