A change was made in PowerBuilder 10.2.1 Build 9716, PowerBuilder 10.5.1 Build 6505, and PowerBuilder 11.0 Build 5021, to correct an anomalous behavior when the SelectedTab property was applied at runtime to a tab whose Visible property was set to false.
As a result of this change, there is a change in the behavior of the OpenTab and OpenTabWithParm functions. In previous releases, calling the OpenTab or OpenTabWithParm function to open a user object as a tab page displayed the tab page even if the user object's Visible property was set to false. In current releases, the user object's Visible property must be set to true for the tab page to display.
