package com.omb.view; import javax.el.methodexpression; import javax.faces.context.facescontext; import javax.faces.event.actionevent; import javax.faces.event.methodexpressionactionlistener; /** * jsf utilities. */ public class facesutils { public static methodexpression createaction(string actionexpression, class<?> returntype) { facescontext context = facescontext.getcurrentinstance(); return context.getapplication().getexpressionfactory() .createmethodexpression(context.getelcontext(), actionexpression, returntype, new class[0]); } public static methodexpressionactionlistener createactionlistener(string actionlistenerexpression) { facescontext context = facescontext.getcurrentinstance(); return new methodexpressionactionlistener(context .getapplication() .getexpressionfactory() .createmethodexpression(context.getelcontext(), actionlistenerexpression, null, new class[] {actionevent.class})); } } screen.xhtml
