Turbine Exceptions after a Redirect in an Action

[Chris Holman <ch...@owl.co.uk>]

I have been using Turbine for a couple of months now.
I've been very impressed at the speed at which applications can be put
together.

Able to get round most problems using the archived mailing lists, but this
ones stumped me.

We are writing a doc management system. We use an Action to save the
uploaded file data and then use a re-direct to get round the problem of page
refresh reloading that document as a new document.

This seems to work fine as far as the upload is concerned, but we are seeing
a TurbineException(See 'turbine.log' below) as turbine tries to decode the
redirected request. As far as I understand it, it is trying to find the
previously uploaded document(which isn't there after the redirect) due to
the http header still indicating a file upload.

After the TurbineException, the page seems to be redirected again but
renders correctly the second time. Is this to do with the redirect handling
code in the turbine.java Servlet?

Do I need to change anything in the response?(See 'Redirect Code' below)

PS: I noticed that counters have been suggested as one solution to the page
refresh issue, but a page re-direct is a quicker solution for us, if a
little dirty.

Regards,
Chris

************** Start Redirect Code ************
TemplateLink tl = new TemplateLink( data );
tl.setPage( "MySecureScreen.vm" ).addPathInfo( "identifier",
docObj.getDocID() );
data.setRedirectURI( tl.getURI() );
data.setStatusCode( 302 );
// data.setContentType("text/html") //doesnt seem to work.
