Ouch! Looks like it was simply a serialization issue.. ^^; Is there a way to 
trigger blocking Serialization exceptions instead of simply logging them?
Many thanks :)

Hi everyone!
I have a form with some fields and a submit button which says Save and print.
The button has setDefaultFormProcessing(false), and overrides onSubmit so that the form 
model object is sent to the persistence layer and printed immediately afterwards. The 
persistence layer *may* alter the object, so I have to reload it. My problem is that this 
reloading causes a page expired when I press the button for a second time.

My onSubmit:

if(getForm().process()){
   MyBean data=getForm().getModelObject();

   data=Persistence.save(data);

   // Create PDF and send it to the browser
   IResourceStream s = new ByteArrayResource(application/pdf, 
buildPDF(data)).getResourceStream();
   RequestCycle.get().setRequestTarget( new ResourceStreamRequestTarget(s) );

   getForm().setModelObject(data);
}

I think the page expires because sending the PDF to the browser blocks the 
request cycle, so the browser never renders the new version of the page.. Is there a way 
to do this? Am I doing Something Wrong? ^__^;
Many thanks for your time!

Page expired upon file download + model update

Hi everyone!
I have a form with some fields and a submit button which says Save and print.
The button has setDefaultFormProcessing(false), and overrides onSubmit so that 
the form model object is sent to the persistence layer and printed immediately 
afterwards. The persistence layer *may* alter the object, so I have to reload 
it. My problem is that this reloading causes a page expired when I press the 
button for a second time.

My onSubmit:

if(getForm().process()){
   MyBean data=getForm().getModelObject();

   data=Persistence.save(data);

   // Create PDF and send it to the browser
   IResourceStream s = new ByteArrayResource(application/pdf, 
buildPDF(data)).getResourceStream();
   RequestCycle.get().setRequestTarget( new ResourceStreamRequestTarget(s) );

   getForm().setModelObject(data);
}
