我有一个模板 xhtml ：

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">

<f:view />
<h:head>

</h:head>

<h:body>
    <f:facet name="last">
        <h:outputStylesheet name="/ressources/css/default.css" />
    </f:facet>

    <!-- Bandeau -->
    <p:layout fullPage="true">
        <p:layoutUnit position="north" style="height: 50px;">
            <h:form id="menuForm">
                <div id="bandeau">
                    <div id="menu" class="bandeauElement">
                        <p:commandLink action="#{myBean.allerVersPremierePage}">
                            <i class="fa fa-arrow-left" style="color: white" />
                            <f:ajax render="content cssContent contentForm" />
                        </p:commandLink>
                    </div>
                </div>
            </h:form>
        </p:layoutUnit>
        <p:layoutUnit position="center">
            <h:form id="contentForm">
                <ui:insert name="content">                                                      
                    <ui:include src="#{facePainter.mainContent}" />                        
                </ui:insert>  
            </h:form>

            <ui:insert name="cssContent"> 
                <h:outputStylesheet library="css" name="#{facePainter.cssContent}"  />                     
            </ui:insert>            

        </p:layoutUnit>
    </p:layout>
</h:body>
</html>

我有一个 FacePainter：

@ManagedBean(name="facePainter")
@SessionScoped
public class FacePainter {

    private String mainContent = "ressources/fragments/premierePage.xhtml";

    private String cssContent = "ressources/css/default.css";

    //getters/setters

}

我有一个 AccueilBean.java ：

public void allerVersDeuxiemePage() {
    facePainter.setMainContent("ressources/fragments/deuxiemePage.xhtml");
    facePainter.setCssContent("ressources/css/deuxiemePage.css");
}

当我点击我的 commandLink 时，第二页正在加载。但是如果我检查我的 CSS，我没有“ressources/css/deuxiemePage.css”但是 href=RES_NOT_FOUND

你知道为什么吗 ？谢谢

正文已正确更新，但我不明白为什么我需要按 F5 才能更新 CSS。你有什么想法吗:)？我认为这是我制作 CSS 之前的最后一个问题 :'(
