I did some debugging using firebug - Here is what is happening :

When I choose HTML report there is a POST (posts form data - essentially 
filters selected by user) followed by GET (actual HTML page is returned 
from the template)
But when I choose PDF report - I don't see any POST/GET in the firebug. 
(But PDF is indeed returned to the browser)
Now that form is in weird state, if I click Submit one more time, I get
POST, GET and another POST in firebug, but user doesn't see anything.

Do I need to return 200-OK (equivalent) when I return PDF data via 
appreport ?

Please help
