switcher switcher

The switcher component dynamically decides which facet component should be rendered. It has two properties. The switcher will render the facet matching "facetName"; however, if no such facet exists (or "facetName" is null), and "defaultFacet" has been set, then that facet will be used instead. (It's possible to achieve this same functionality by using a panelGroup and binding the "rendered" property of each child, but this component can be simpler. Ordinary children of the switcher component are not rendered at all.)

The switcher is a purely logical server-side component. It does not generate any content itself and has no client-side representation (no client component). Hence switching which facet of the switcher renders requires a server round-trip.

Initial render works as normal, but you cannot switch facets since only the displayed facet is rendered.
