                                PhaseId phaseId)

Process the component according to the rules of the given phase ID.

Parameters:

context - The faces context to work with.

phaseId - The current phase ID.

processSuper

protected void processSuper(FacesContext context,
                            PhaseId phaseId)

Helper method to delegate the processing further to the UIComponentBase superclass which will handle all children.

Parameters:

context - The faces context to work with.

phaseId - The current phase ID.
