FW: file download issue

[ra...@L-3com.com]

 
Brendan,
 
I saw your post on apache as follows:
 
Our application has a requirement to export certain data as a

comma-delimited file to the user.  To do this, our action class does the

following:



response.setContentType("text/html");

response.setHeader("Content-Disposition", "attachment;filename=3D\"" +

defaultFileName + "\"");

PrintWriter out =3D response.getWriter();

...

out.println(data); // in a loop to output all the rows

...

facesContext.getApplication().getStateManager().saveSerializedView(faces

Context);

facesContext.responseComplete();

return null;



The above works fine in that, when the action is invoked, the user gets

the typical "file download" pop-up (with the options: open, save,

cancel, or more info).  The pop-up gets displayed with following

checkbox checked and disabled: "Always ask before opening this type of

file."



The problem is that, if I press the "open" button, the same dialog

re-appears, but this time, the checkbox is enabled.  Only after I hit

"open" again can I actually see the data.  By contrast, if I hit the

"save" button, I only have to do that once.



Can anyone explain to me why I have to hit the "open" button twice on

the "file download" pop-up, given the code I've listed above?
I am currently working on an application that has the exact same error.  Did
you ever get a fix for this?  IF so, could you please tell me what it is?
Thank-you,

I have this problem too! Is there a fix or workaround for this? Why does this
error not appear in the tobago demo application (Download PDF page)?

Best regards, 
Carsten

I don't remember posting this.  Are you sure I posted it. I do know that
I had a problem with file download. It would state that it could not
find the file. I found that on a linux system, the file download
expected a windows temp dir off root, not the unix tmp dir that existed.

Can you send me a link to this thread, perhaps it will refresh my
memory.

 

Suzanne
