Richfaces fileuploader nullpointer Firefox [英] Richfaces fileuploader nullpointer firefox

问题描述

随着Firefox 62的引入，我现有的RichFaces fileuploader在尝试对上传的文件进行解码时突然抛出空指针.这是在JBoss 5.1环境中使用Richfaces 3.3.3.我尝试上传不同的图像类型均无济于事.还需要注意的是，此问题仅在Firefox 62上出现，以后所有其他浏览器都可以正常工作.

With the introduction of Firefox 62 my existing RichFaces fileuploader is suddenly throwing null pointers upon trying to decode the uploaded file. This is using Richfaces 3.3.3 on a JBoss 5.1 environment. I've tried uploading different image types to no avail. It's also to be noted that this issue only occurs on Firefox 62 and later all other browsers are working fine.

推荐答案

您可以使用NPE这样的东西.

You can works with NPE something like this.

1)覆盖FileUploadRenderer

1) Override the FileUploadRenderer

public class CustomFileUploadRenderer extends FileUploadRenderer {

@Override
protected void doDecode(FacesContext context, UIComponent component) {
    try {
        super.doDecode(context, component);
    } catch (NullPointerException e) {
        LOGGER.info("double decode error ignored", e);
    }
}

2)将自定义类添加到faces-config.xml

2) add custom class to the faces-config.xml

    <render-kit>
     <renderer>
          <component-family>org.richfaces.component.FileUpload</component-family>
          <renderer-type>org.richfaces.renderkit.html.FileUploadRenderer</renderer-type>
          <renderer-class>com.nnn.web.jsf.component.CustomFileUploadRenderer</renderer-class>
     </renderer>
</render-kit>

对我有用.
