Method Detail

findClosestNamingContainer

public static UIComponent findClosestNamingContainer(UIComponent component,
                                                     boolean returnRootIfNotFound)

findClosest

public static <T> T findClosest(Class<T> type,
                                UIComponent base)

findRootComponent

public static UIComponent findRootComponent(UIComponent component)

findComponent

public static UIComponent findComponent(UIComponent findBase,
                                        String id,
                                        char separatorChar)

Find the component with the specified id starting from the specified component.

Param id must not contain any NamingContainer.SEPARATOR_CHAR characters (ie ":"). This method explicitly does not search into any child naming container components; this is expected to be handled by the caller of this method.

Returns:

findBase, a descendant of findBase, or null.

findComponentChildOrFacetFrom

public static UIComponent findComponentChildOrFacetFrom(UIComponent parent,
                                                        String id,
                                                        String innerExpr)

callValidators

public static void callValidators(FacesContext context,
                                  UIInput input,
                                  Object convertedValue)

getPathToComponent

public static String getPathToComponent(UIComponent component)

isRendered

public static boolean isRendered(FacesContext facesContext,
                                 UIComponent uiComponent)

Call UIComponent.pushComponentToEL(jakarta.faces.context.FacesContext, jakarta.faces.component.UIComponent), reads the isRendered property, call UIComponent.popComponentFromEL(jakarta.faces.context.FacesContext) and returns the value of isRendered.

getPathToComponent

public static void getPathToComponent(UIComponent component,
                                      StringBuilder buf)
