It's not that I necessary want to see the page refreshed with updated form
values. In fact, I would prefer that the user not leave the page at all.
All the form contains is a checkgroup of "things" to include in the PDF.
All I want to do when the button is pressed is view/download the PDF but the
form with the checkgroup needs to be submitted first so I can see what was
checked when I generate the PDF.
I suppose taking the ResourceReference's and using it in the onload would
work but it seems like such a hack, not to mention that it might cause
problems if the user uses the back button. While working on my
DynamicWebResource, I was able to download a PDF and continue using my
application using a link (assigned to either a link or button in HTML.) The
only problem is that it doesn't do a submit. Accessing the
DynamicWebResource from a button works but makes my app non-responsive.
What I would like to do is either make the ResourceLink somehow submit my
form or, even better, make a button component that handles the request in a
way that doens't break Wicket. Ideas/suggestions?
