Show / Hide (G)UIBBs on FPM Dialog Box (raised from OIF)

Hi Experts,

Is there any way to show / hide certain UIBBs during runtime on dialog box? E.g. After ticking a checkbox or pressing a button on the dialog box.

I managed to get the OIF reference to the dialog box UIBBs, but then I realized that for the dialog box, there is no way to influence the visibility of UIBBs, but only the UIBBs placed at the OIF application (identified by Mainview ID / Subview ID / UIBB key).

I'm using GUIBBs on the popup, so the possibilities are even more restricted...
