getFacetName(javax.faces.component.UIComponent parent) |
static java.util.Locale |
getLocale(javax.faces.view.facelets.FaceletContext ctx,
javax.faces.view.facelets.TagAttribute attr)
According to JSF 1.2 tag specs, this helper method will use the
TagAttribute passed in determining the Locale intended.

getViewRoot(javax.faces.view.facelets.FaceletContext ctx,
javax.faces.component.UIComponent parent)
Tries to walk up the parent to find the UIViewRoot, if not found, then go
to FaceletContext's FacesContext for the view root.

public static void addComponent(javax.faces.view.facelets.FaceletContext ctx, javax.faces.component.UIComponent parent, javax.faces.component.UIComponent child)
Add the child component to the parent. If the parent is a facet, check to see whether the facet is already defined. If it is, wrap the existing component in a panel group, if it's not already, then add the child to the panel group. If the facet does not yet exist, make the child the facet.
