formpanel already added to contentpanel but not showing. But buttons in the contentpanel are showing. Is there a force redrawing / recalculating of the contentpanel?

Hi,
Include 3 main player classes here - SynopWeb,CodedSynopPanel and SynopForm. SynopWeb implements entrypoint, here codedsynopanel and synopform is added to viewport, which is then added to the rootpanel. Upon launching, codedsynoppanel will be displayed first, when the decode button in the codedsynoppanel is pressed, the synopform (a contentpanel) appears, but only the added buttons are displayed, the formpanel does not show.
I need help, please help me, thank you.
