Thanks james/ron,
I finally gathered some courage to look at the source code :)
Ok I just want to check for the presence of the User object in the session
in my ClassAnnotationEnhancementWorker. I basically need a
InjectStateFlag kind of functionality in my Worker (not the page) where i
can check if the 'user' object is already present in the session.
Then i want to throw PageRedirect to Login page...usual stuff.
Am not actually *enhancing* the Page as in ..am not doing any nifty byte
code generation stuff.
Since I cannot use @InjectState within my Worker? , I need to figure it out
myself by querying hivemind.xml? - so basically my Worker needs to be aware
of say the "user" configured in hivemodule.xml
How can I query the hivemind and ask if the hivemind container contains an
instance of "user" in "session" scope already. I dont want it to instantiate
"user" though.
Or the only way to throw a PageRedirect is to dynamically enhance the Page
by making it implement PageValidateListener?
Sorry for such basic questions.
thanks
Karthik

The tapestry-acegi library does exactly this. When it sees an Acegi
@Secured annotation on a class/method, it uses a worker to enhance the
class. So, you can either use what I've already created or refer to
the source to see how to do what you want. If you have any questions
about the code, don't hesitate to ask. Hope that helps.
