Question

嗨我正在做一个带有primefaces的文档管理系统5.y做了一个搜索功能，搜索按钮位于左侧菜单的模板中，搜索结果显示在中心单元布局中。如果我搜索，搜索功能运行良好，但是当我对结果进行调整并尝试再次搜索时，结果不会刷新

我的模板文件

            </p:layoutUnit>

        </p:layout>

    </h:body>

   </f:view>
 </html>

我可以搜索的xhtml之一

<ui:define name="UIlurlImport">

    <h:panelGrid columns="1" cellpadding="5">
        <h:form>
            <p:growl id="messages" showDetail="true" />

            <p:panel id="panel" header="URL import" syle="vertical-align:top;">

                <p:outputLabel for="url" value="URL" />
                <p:inputText id="url" value="#{urlImportBean.url}" required="true"
                    label="URL">
                    <f:validateLength minimum="5" />
                    <p:ajax update="msgOutput" event="keyup" />
                </p:inputText>
                <p:message for="category" id="msgOutput" display="icon" />
                <p:outputLabel for="category" value="Category" style="padding:10px" />
                <p:selectOneMenu id="category" value="#{urlImportBean.category}"
                    label="category" filter="true">
                    <f:selectItems value="#{categorieBean.items}" id="selectCategoy" />
                    <p:ajax />
                </p:selectOneMenu>
                <p:commandButton value="Import" update="messages"
                    icon="ui-icon-home" action="#{urlImportBean.importImage}" />

            </p:panel>
        </h:form>


     </h:panelGrid>
    </ui:define>
</ui:composition>

显示结果，但如果我搜索，则不会更新任何内容

<ui:define name="Uisearch">
    <h:outputScript library="js" name="pdfobject.js" target="head" />
    <h:panelGrid columns="1" cellpadding="2">

        <p:panel id="panelResults" header="Results">

            <p:dataList value="#{documentBean.documentsMatched}" var="document"
                type="definition">

                <h:outputLink value="file/#{document.pdfPath}" target="_blank">view  document</h:outputLink>   
                <div id="pdf2">
                    <object data='file/#{document.pdfPath}' type='application/pdf'
                        width='1000px' height='400px'>

                        <p>
                            It appears your Web browser is not configured to display  PDF
                            files. No worries, just <a href='file/#  document.pdfPath}'>click
                                here to download the PDF file.</a>
                        </p>

                    </object>
                </div>


            </p:dataList>

         </p:panel>

     </h:panelGrid>

  </ui:define>

</ui:composition>

boton调用的方法

    public String search2()
 {
    System.out.println("searching "+ paramSearch);

    DocumentModel doc = new DocumentModel();
    this.setDocumentsMatched(doc.searchText(this.paramSearch));
    System.out.println("search");
    return "UIsearch";

}

提前感谢您的时间和下水道

Answer 1

使用操作方法中的重定向：

return "UIsearch?faces-redirect=true";

我不确定它的工作原理，但我的猜测是浏览器正在缓存页面，现在被迫重新加载。

在同一页面jsf中更新面板
