Workflow Instances not COMPLETED


Level 1


I am creating a simple workflow with Process Step, Assign Task, Generate Document Of Record and Send Email.

I am able to complete the workflow successfully. However, the workflow instance is still showing RUNNING. It is intermittent.

Can you please tell me how to complete a workflow OR make sure its status changes to COMPLETED?

Sometimes I get the below error message:

com.adobe.granite.workflow.WorkflowException: Process implementation not found:

    at com.adobe.granite.workflow.core.job.HandlerBase.executeProcess(

    at com.adobe.granite.workflow.core.job.JobHandler.process(





    at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)

    at java.util.concurrent.ThreadPoolExecutor$ Source)

    at Source)

Please help me understand why it is happening.

Regarding this error, it is likely that your bundle is not started. Check it in /system/console/bundles

"Process implementation not found:"

You can terminate running workflows by going to host:port/workflow and go to the "Instances" tab. Right click the instance to terminate it

Does the process involve assign task or sending workflow item to a user's inbox?

Yes, Mayank. It involves assign task and sending workflow item to a user's inbox.

I would like to be able to complete the running workflows automatically. Some workItems keep showing RUNNING, & they don't complete AND some of them completes automatically after a couple of hours.

Can you send high-level workflow details?
