小编baj*_*r83的帖子

我无法在PrimeFaces 3.5上创建fileUpload组件来触发事件.我已经阅读了很多关于该主题的帖子,并在那里提出建议,但仍然无效.我尝试了所有模式(简单,自动,高级)但没有成功.

如果我使用JSF规范中的标准inputFile标记,它可以正常工作.

这是我的web.xml文件:

    </session-timeout>
</session-config>
<welcome-file-list>
    <welcome-file>faces/home.xhtml</welcome-file>
</welcome-file-list>  
</web-app>

这是我的视图页面的一部分,其中包含fileUpload标记:

<h:form enctype="multipart/form-data"> 
   <p:dialog id="basicDialog" header="Add pictures" widgetVar="dlg1" >  
       <p:fileUpload fileUploadListener="#{galleryManagedBean.addPicturesToGallery}" multiple="true"/>
   </p:dialog> 
</h:form>

使用从标记调用的方法从托管bean中提取:

@Named(value = "galleryManagedBean")
@RequestScoped
public class GalleryManagedBean {
    public void addPicturesToGallery(FileUploadEvent …
