in the example
http://svn.apache.org/viewvc/tapestry/tapestry4/tags/4.1.1/tapestry-examples/Vlib/src/java/org/apache/tapestry/vlib/VlibPage.java?revision=488094&view=markup

@InjectState("visit") the @InjectStateFlag("visit") method is called to
ensure that state-object is present or not.
hope i could help!
