Olá,

Estou precisando de uma ajuda… tenho uma bean(MapsBean) e nele tem um metodo que recebe o caminho de um arquivo XML e carrega um mapa. assim

Preciso que meu método getLoadMap recebe um parametro que vem do meu XHTML via <ui:param name=“path” value="#{item.link}"/>

xhtml ========

&lt;f:subview id="bodyRightPanel" rendered="#{reportsNavMenuMapsBean.loadMap}"&gt;
        &lt;div id="page-body-right-maps"&gt;

..............

        &lt;/div&gt;
&lt;/f:subview&gt;

bean =======

public boolean getLoadMap() { 
        try{
            showContent("/home/maps/defaultMap.maps");        
        } catch (Exception e) {
            System.out.println(e);
        }
        
        return true;
        
    }

Alguem pode ajudar ???

cara,

vc deve fazer seu metodo do bean receber uma String e no xhtml vc passar o parametro para o metodo do seu beans, se nao me engano, vc vai ter ter que fazer seu metodo com o nome completo getLoadMap(path) (nao tenho certeza, mas a ideia do da coisa é essa)

&lt;f:subview id="bodyRightPanel" rendered="#{reportsNavMenuMapsBean.loadMap}"&gt;

testa as duas formas

<f:subview id="bodyRightPanel" rendered="#{reportsNavMenuMapsBean.loadMap(#{path})}">

<f:subview id="bodyRightPanel" rendered="#{reportsNavMenuMapsBean.getLoadMap(#{path})}">
