FileUploadEvent listener reset the list value

[wish79]

Hello All,

i make an example of upload file from richfaces showcase it is working successfully , but i notice if i changed the backing bean to viewscope the files list inside the FileUploadEvent listener will be rest every time that i upload new file , the code as follow :

protected List<UploadedImage> files = new ArrayList<UploadedImage>();

public void FileUploadlistener(FileUploadEvent event) throws Exception {
        UploadedFile item = event.getUploadedFile();
        UploadedImage file = new UploadedImage();
        file.setLength(item.getData().length);
        file.setName(item.getName());
        file.setData(item.getData());
       
        files.add(file);
      }

but when i changed the scope to session the files still contain the old files, is it mandatory to the backing be session or there is something wrong ?

Regards

[RF-13323] FileUploadEvent listener reset the list value with Viewscope - JBoss Issue Tracker

[wish79]

the problem was :

<context-param>

  <param-name>javax.faces.STATE_SAVING_METHOD</param-name>

  <param-value>client</param-value>

</context-param>

the file upload dose not work with view scope with javax.faces.STATE_SAVING_METHOD = client

set the value to server it works
