Hi Howard,
thank you for pointing this out ;)
I did not expect this exception because I expect getService() to return a
PageService - not a DirectService.
In my understanding (which seems to be wrong :) ) the DirectService was
'consumed' on the Login-page to do the submit.
After this, a callback is fired leading to the page where the exception occurs
- so I expected to be in 'page mode' again :(
But actually this seems to be very wrong.
What I need in this pageValidate is the absolute url of the PAGE with all its
parameters, states and so on. My method was working fine - as long as there
were only PageServices involved :(
Maybe someone could give me a hint how to obtain this complete page path
without using getService() ?
Thanks again !
Gerald
