I’m posting some strings in my Session with the call
request.getSession().setAttribute(key, value);
And making the redirect with
response.sendRedirect(urlRedirect);
In almost all cases the values is there after the redirect.
But sometimes I can only read this value in the next page view, not in the redirect. There is no common behavior.
Someone has faced the same problem?
The problem was solve by changing the way of submit.
The page was submitting the data only changing the value of location.href to the Servlet Action.
We only call the submit function from the page form, and the session attributes works fine!
