In the first case (when you press the button) you are in the context
of a session, thus the application is also know. In the second case
the application is not know, presumably because you call the method
from some background thread.
Probably you could avoid the error by somehow faking a session so that
the URL could be generated the usual way. Alternatively you could
register the URL yourself with your application object by navigation
through the dispatcher to the application.
Hope this helps,
