Shing,
I did change the 'Visit' id to something else, 'message', as a test and
still get the exception of webRequest being null.
From your website: HelloMessage message = (HelloMessage)
getAppStateManager().get("message");
How are you calling getAppStateManager(), from what class? How are you
getting access to the registry from a POJO?
Thanks,
Joseph

I have noticed that in the retrieveVisit method of
InjectStateWorker.java :
visit = (Visit)
_applicationStateManager.get("visit")
;
But in the hivemodule.xml, the state object name is
'Visit' with a captial V.
You might like to rename 'visit' to something else.
I do not know whether it would conflict with the
default visit object (the one that could be
specified
in
.application.)
I have written up an example on injecting an aso
into
a service and put it on
http://lombok.demon.co.uk/tapestry4Demo
If you like, you can take a look and see if it
helps.

I would like to get access to my ASO 'Visit' from
a
servlet filter let's
say. I have used a piece I saw Howard post where
I
am subclassing the
ApplicationServlet which will provide access to
the
HiveMind (HM)
registry. I would think then calling from
anywhere
in the app to the
servlet would give me the HM registry. Once I
have
the registry, I
would think I can access it's services. I saw an
example of injecting
an ASO into a POJO using a service and implemented
that below. It is
not really the ASO getting injected, rather it is
the
ApplicationStateManager (ASM) getting injected. I
am getting the
service, getting the ASM, but when attempting to
get
'Visit' from the
ASM, an exception is thrown visible in the logging
below. I then moved
my call to a page class to see if that would
change
things and it did
not. Debugging my servlet shows the registry
obtained has many services
including mine.
I have seen many references to 'HiveUtils
ObjectBuilder' and would like
to get this working before attempting use of that.
Also saw in this
list: 'how to inject visit object into pojo',
'how
to inject aso in
service', 'injecting an aso into a hivemind
service', and 'injecting
an aso into a service' which all relate to this
post.
Can I get the HM registry from my servlet and is
it
valid? Is there
another way to get the registry? Suggestions on
getting the ASO 'Visit'
from a POJO? Is my code invalid?
Thanks,
Joseph

ApplyServlet.getRegistry().getService(IInjectEnhancementWorker.class);
