1. panelLayout bug? icefaces.org
2. Toggling panelLayout visibility icefaces.org
Changing the "visible" attribute to "rendered" fixed the issue. I had originally set it up this way, but the panel would appear and overlap the rest of the page, rather than push the page content down. This seemed to be a bug in 1.7 because, once I upgraded to 1.8, this worked perfectly.
3. panelLayout 'visible' attribute does not work icefaces.org
4. ICEfaces counterpart to UI:PanelLayout ?? icefaces.org
