title: How to set a value to an application item in oracle apex 5
body: <p>I have several tabs.  There is a date picker on each tab.  I need that date to be the same on all tabs no matter what.  So, if the user changes the date on Tab 1, then goes to tab 2, the date on tab 2 will have changed also.  I have never created an application level item before and I thought that might be the most efficient way to accomplish what I need (by setting that item's value to the date the user selected). My problem is that I don't know how to set the value of the application item and also how to retrieve that value on another tab.</p>
