[Springframework-developer] Spring Web Flow - _eventId

[Will B. <wil...@ra...>]

When returning from a view state, doesn't the view have to pass an
_eventId request parameter back to the flow so it can determine which
transition to make? When doing so, I receive the following error:

java.lang.IllegalArgumentException: The '_eventId' request parameter (or
'_mapped_eventId' request attribute) is present in the request --
programmer error?
at org.springframework.util.Assert.hasText(Assert.java:140)
org.springframework.web.flow.support.HttpServletFlowExecutionManager.handleRequest(HttpServletFlowExecutionManager.java:192)...

Is there something that I am missing here?

Thanks!

Will
