Related to this question, we created our Activiti workflow using the Designer and we are also getting these warnings during deployment:
11:46:20,903 WARN [BpmnParse] Invalid reference in diagram interchange definition: could not find lane1
11:46:20,904 WARN [BpmnParse] Invalid reference in diagram interchange definition: could not find ApprovalWorkflowContainer
How can avoid these warnings being logged? Since the workflow seems to be working like it should.
