FacesContext responseComplete + response sendRedirect

[ricardo.gomes]

Hello all,

I would like to download a file AND redirect to a page.

If I use the code bellow it does not enable file download, just if I remove the second line. But in this case, it does not redirect.

FacesContext.getCurrentInstance().responseComplete();
response.sendRedirect("pesquisar.seam");

Does anyone have any suggestion?

Hi Ricardo.
Did you get to solve this problem?
I'm having a similar issue.
My download only works once and don't know why.

Any help?

regards,

You cannot download and redirect at the same time, this is simply a limitation of the HTTP protocol (it has nothing to do with Seam or JSF): when processing a request either you provide a single response (a webpage or a download) or you redirect to another resource. You cannot do both at the same time.

Possible workarounds for this issue are:

1. Open download in a separate browser window (using an onclick javascript action). This does not work if javascript is disabled. This also requires you to have a RESTful link to the file you're trying to download.


2. Serve response with a <refresh> meta tag (that makes the page reload). On refresh, issue the response. This also requires javascript, I think (I have never used this solution).


3. Redirect and serve download file from an iframe embedded in the redirected-to page. This is my preferred solution, as it does not require javascript.
