Close tab application automatically

I have a tab application with 5 tabs. If tab#1 app is open and I click tab menu to open tab#2, I want it to close tab#1. I don’t see any tab “events” where I could put something like this. What I am trying to accomplish here is a refresh of tab#1 because some choices in tab#2 would affect the blocks/fields displayed in tab#1. I can do a reload of tab#1 when I go back to it but don’t want that burden on users (since they will forget to do it half the time and make my life insane).

That works for one table, but my tabs are actually holding forms which all reference different tables. When I make a change in tab 2, it will update something on tab 1 table so now tab1 form needs to show the updated info. It works if we click reload or if I close the tab and reopen it. I went to simulate the reload.
