jsf 2 - how show view page with JSF 2.2 -


please, need code. trying make query invoice on page. on page(facturashow.xhtml) shows null. in console comes result system out.

facturabean.java

public string outcome() {      facescontext fc = facescontext.getcurrentinstance();     this.visualizarfact = integer.parseint(getnumerofacturaparam(fc));     system.out.println("factura : " + this.visualizarfact);     return "facturashow.jsf"; }  //get value "f:param" public string getnumerofacturaparam(facescontext fc) {      map<string, string> params = fc.getexternalcontext().getrequestparametermap();     return params.get("numerofactura");  }

facturaindex.xhtml page shows invoice list invoice used print, cancel, display. near end of code, find commandlink call facturashow id="reportefactura6".
