Running Operation in Seam context may raise NPE

SeamOperationFilter takes care about Seam Context Initialization.

For doing that, it needs to access HttpServletRequest.
In usual use cases, the Chain/Operation is run via JAX-RS and the request is automatically available in AutomationContext.

Unfortunately, when the Operation/Chain is run from Java Code the AutomationContext may not contain any request.
This is typically the case for the WF GraphRunner.
