Hello, I'm try to start a new symfony project with workflowerBundle and symfony 2.7.3 , but i have a little problem

my composer file:

"phpmentors/workflower-bundle": "^1.0"

my AppKernel :
...
new PHPMentors\WorkflowerBundle\PHPMentorsWorkflowerBundle()

in my app/config/services.yml

imports:
- { resource: "@PHPMentorsWorkflowerBundle/Resources/config/services.xml" }

but when I try run my app generate the next problem

RuntimeException in CheckReferenceValidityPass.php line 100: The definition "phpmentors_workflower.doctrine_lifecycle_listener" has a reference to an abstract definition "phpmentors_workflower.workflow_serializer". Abstract definitions cannot be the target of references.

Sorry for lack of documentation. Here is a getting started guide. I hope this can help you.

Here is a workflow LoanRequestProcess,

• Design a workflow in BPMN 2.0 definition
  • See the supported workflow elements
  • Write conditions in connecting objects as expressions for Symfony ExpressionLanguage
    • Process data which are provided by ProcessContextInterface can be referred as $foo === true
  • Store the workflow as LoanRequestProcess.bpmn in your BPMN 2.0 definition directory
• Design an entity LoanRequestProcess
  • Implement ProcessContextInterface and WorkflowSerializableInterface
  • Add properties for your application as BPMS such like $currentActivity if necessary
  • See LoanRequestProcess in this comment
• Design domain services to start processes, allocate/start/complete work items, etc.
  • Implement ProcessAwareInterface
  • WorkItemContextInterface objects will be mostly created in controllers, commands, and listeners
  • See LoanRequestProcessCompletionUsecase in this comment
• Configure the service container
  • Map workflows to domain services
  • See services.yml in this comment
