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. I can't recollect
now fully, but somehow was possible, that saved state was removed from
server cache on successful restore view (something with params
NUMBER_OF_SEQUENTIAL_VIEWS_IN_SESSION and NUMBER_OF_VIEWS_IN_SESSION)
and viewState on client not updated because of ajax error handling.
Is VVE reproducible when you throw an exception in
garageSaleJSFActions.updateCart ?
Regards,
Kočičák
