We have an OIF which contains a Form GUIBB and a Tabbed GUIBB. We are using the PLM framework alongwith GUIBBs. Currently we have to set the variants of the Tabbed GUIBB from an instance of the OIF which embeds it. How do we do this ? Any other ways of setting the variants ? We are not using Component Configurations or Controller. We are using simple GUIBBs.
