Hi all,

I am wondering what is the proper way of checking in the controller if the
request invocation is the invocation of html or maybe pdf or excel?

I can see in my controller method that if user clicked on 'export to pdf'
link within the displaytag table the request object has several parameters
with strange names like 6578706f7274 or d-1332823-e.

I can check if there are such parameters in my request object - but what is
the recommended way of checking if the current invocation is an export to
pdf or not?

Regards
