In my how-to, appStateManager is injected to
the tapestry service asoSerivce by hivemind.
The following piece of code is meant to be in the
.java
class of my asoService.
HelloMessage message = (HelloMessage)
getAppStateManager().get("message");
Also, in the .java of my asoService, there is
getter/setter method for the property
appStateManager.
I have noticed that in your
service-point id="InjectStateWorker", you have
<set-object property="applicationStateManager"
value="infrastructure:applicationStateManager"/>
try replacing it by
<set-service property="applicationStateManager"
service-id="tapestry.state.ApplicationStateManager"/>
