Primefaces 4文件上传不会为所有事件调用方法

Question

当我上传图像7文件时，primefaces-4没有为每个文件调用侦听器方法。有时，调用3或4次，根本没有。顺便说一句，如果我只测试主面，这是可以的。我也用omnifaces-1.7

<p:fileUpload allowTypes="/(.|/)(gif|jpe?g|png)$/" fileUploadListener="#{MyUploadBean.handleAttachment}" 
    id="attachment" mode="advanced" multiple="true" sizeLimit="3000000" 
    update="imageGrid"/>

MyUploadBean.java

public void handleProposalAttachment(FileUploadEvent event) {
    UploadedFile uploadedFile = event.getFile();
    String fileName = uploadedFile.getFileName();
    System.out.println(fileName); <-- Here, I can see some uploaded file name.
}

我试过了，它对所有文件都有效，没有问题。我认为你的问题是:你把<p:fileUpload>和另一个标签以某种形式，试着把<p:fileUpload>单独放在形式上，它的工作很好:)不要忘记更新fileUpload的表单和image的表单。试试吧，我等着看是否可以，如果不行，把整个页面
