@Martin, I will try the suggestion above to reproduce the issue by throwing a exception in garageSaleJSFActions.updateCart or introducing an artificial rollback exception. If I can recreate consistently I will be able to fix it fast.
@Mark, I am also investigating my session persistence settings to understand why the viewstate is disappearing when an exception occurs. --Thanks for the input guys. Once I have tried the suggestions I will circle back and provide feedback, Rohit Kelapure On Fri, Dec 30, 2011 at 6:49 AM, Martin Koci <[email protected]>wrote: > Hi, > > I had similar problem once and it was caused by combination of unhandled > exception + ajax-error. > > When exception occurs in partial/ajax request/respose (for example SQL > exception), JSF send back to client XML with following structure: > <partial-response> > <error> > <error-name>...</error-name> > <error-message>...</error-message> > </error> > </partial-response> > > this XML does not contain ViewState update element.
