LDEV-1997 Save after export keeps exporting the file but not saving...The "dispatch" param was not being reset after an export, so from then on each submit was assumed to be an export action, simple fix
LDEV-1912 set session timeout programmatically according to lams' UserInactiveTimeout value via a servlet listener rather than hard coding to 120 mins (in some webapps, no session timeout was specified at all).
