Chris,
I'm not sure what the proper solution would be. Your case is very similar to the one I faced while
refactoring the FOP rendering - that's why I was thinking a generic file view handler would be
handy. It would work something like this:
Render the specified screen to a temp file
Branch to a conversion routine (temp file as arg) based on content type
Conversion routine returns converted file
Copy converted file to response OutputStream
Conversion routines could handle FOP, Zip, or any other file format that comes
along.

Thanks for your help Adrian! That helped me track down a workaround (big
smile). in ScreenWidgetViewHandler.java#render(..,..,..,...,.)
there is the section
if (useOutputStreamNotWriter) {
ServletOutputStream ros = response.getOutputStream();
writer = new OutputStreamWriter(ros, "UTF-8");
} else {
writer = response.getWriter();
}
I set useOutputStreamNotWriter to true based on the content type. What should
be the proper solution that can be put back into the community project?
Another ViewHandler or just additional flags to change whether .getWriter() or
getOutputStream() is used?

You'll have to back up in the code some and see how the writer is being
used. If nothing has been
written already, then you can copy the InputStream to the Writer.
If your code is being called from the screen widget, then things get
tricky - since it has probably
already sent out HTML text to the browser.
It would be handy to have a generic view handler for this kind of
scenario.

It won't let me do response.getOutputStream. I get an error that

FileInputStream zipInStream = new FileInputStream(zipFile);
OutputStream browserOutStream = response.getOutputStream();
response.setContentLength((int)zipFile.length());
response.setContentType("application/zip");
// Call a routine to copy bytes from zipInStream to browserOutStream

I'm trying to create a zip file on the fly. I've created it properly
so that it will write to the file system, but I would prefer to
write
to the browser so that the user can download it. This seems like it
should be so simple, but I'm missing it. TIA for any help!
