David,
Thanks for the hint. Though I didn't ask the question, I have seen this
behavior on one or two of my pages. Now I'll have a chance to fix it
perhaps.
Hmm... I went to the link your code points to, but there was really no
mention of *why* this solution works. Do you know who originally figured
this out or why it is necessary? I assume it's because we are skipping
some necessary lifecycle phase when we write to the out and then call
responseComplete?

Simply add these two lines of code before the call to responseComplete():
// Save serialized view or else after clicking on the export
button,
user will have to click TWICE to invoke another action
// See http://swforum.sun.com/jive/thread.jspa?threadID=63566
StateManager stateManager = (StateManager) facesContext
.getApplication().getStateManager();
stateManager.saveSerializedView(facesContext);

Hello and happy new year
Im' using this action method to generate dynamicaly pdf file and send
them to the browser
public String generaContratto(){
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
response.setContentType("application/pdf");
String fileName = "blabla.pdf";
response.setHeader("Content-disposition", " attachment;
filename=\"" + fileName + "\"");
try {
ServletOutputStream out;
out = response.getOutputStream();
ProxyDaoFactory daoFactory = new ProxyDaoFactory();
DocumentBuilder builder = new
DocumentBuilderWrapper(daoFactory,
facesContext.getExternalContext().getInitParameter("fileValut"));
builder.write(offerta,out);
} catch (Exception e) {
...
return "ERROR"
}
facesContext.responseComplete();
return "OK";
}
Everithing works fine: the pdf is generated, downloaded etc.
But if I trigger some other action on the same view it just render the
page again.. I think it does render response phase. Model is not
updated. It act as if navigation (the ugly back button!) button where
used.
Any ideas?
