0022131: AD_Tab_Access for inactive tabs is causing javascript errors

If we mark as inactive a tab that is included in the tab_access for a particular role causes the following error when accessing to the window that includes the tab: "Cannot read property 'viewForm' of null". Added not null validation before accessing objects of view.
