Specifies a numeric response field to be populated when a tab is selected. Each tab within a Tab Panel is identified by a sequential index starting with 0 for the first tab, 1 of the second tab, and so on.
When "tab response" is bound and the user clicks on a tab, then control passes to the RPG program. When the RPG program passes control back to the browser, then the screen reloads. The "active tab" property determines which tab will be active when the screen reloads. Therefore, if you want the clicked tab to become the active tab, then you can simply bind "tab response" and "active tab" to the same field.
Possible Values: Integer. Must be bound
