Adam,
The control is out of the action class and if the user will open or save
the file, there is no problem and the control goes to the JSP page.
For some reason once the error occurs if the user clicks another button
that makes AJAX call to server, the call does not go through but instead
returns cashed results from the previous AJAX call.
Thanks,
Lana.

Subject: RE: struts2 problem when file download dialog is closed
is the user "cancelling" still sending a request to the server and hence
you are trying to return an error - if so i'd assume the http connection
has been terminated and therefore you can't send an http response back.
if its just logged but doesn't stop user experience then leave it.
