I need some help again....
I have a "load information " button and a tab.
When the button is clicked I want to update the tab and then do a table request to the server in this order. (I want the text "loading" at the tab.)
But: The request to the server is always first and then the update of the tab.
How can I change the order, so the tab is updated first and then the request to the server is sent.
