In Arbortext 5.3, a TabBox/TabPanel/GroupBox/TextBox added to the Samples\XUI\Preferences sample shows the child elements. However, switching between Preferences in the left tree does not refresh the old contents in the case of tabs. In 5.4, that sample does not show any of the child elements of the TabPanel. Is there a different way to code that for my application or fixes available if these are bugs?
