Alfresco workflow path does not exist
<p>Hi guys for many times... Alfresco Community kills me, all the time. This time i have deployed a sample bpmn process with a single service task. I start the process from workflow console. And it throws me exception </p>

<pre><code>org.alfresco.service.cmr.workflow.WorkflowException: 05300002 Workflow path activiti$209 does not exist.
