Hello! 

I'm using liferay 7.1.3 GA4 and for Advance File Input is using version 1.0

  • hs.file-attachement.js

As I said, Liferay - Java is not avaliable to get the file when this is draged from the file system.
HTML
              <div class="col-md-12">
                <!-- Advanced File Input -->
                <div class="form-group mb-0">
                  <h4 class="h6 g-font-weight-600 g-color-black g-mb-20">
                    <liferay-ui:message key="neworder.uploadRelatedFile" />
                  </h4>
                  <input class="js-file-attachment" name="fileAttachmentPO[]" type="file" multiple="multiple">
                </div>
                <!-- End Advanced File Input -->
              </div>
JAVA code
12345678
UploadPortletRequest uploadPortletRequest = PortalUtil.getUploadPortletRequest(actionRequest);
Map<String, FileItem[]> files= uploadPortletRequest.getMultipartParameterMap();
for (Entry<String, FileItem[]> file2 : files.entrySet()) {
  FileItem item[] =file2.getValue();
  try {
    for (FileItem fileItem : item) {
      File file = fileItem.getStoreLocation(); <--- File not exist      
      file.exists()  == >  false

Have you any idea if this problem with the component or java perse?

The same behaviour is happening in Chrome and Firefox

Hello,

Have you any Javascript errors or Java errors in the Liferay Portal logs?

There is no actual error but the file is named upload_00000059. without any extencion

  • \LiferayWorkspace\bundles\tomcat-9.0.17\temp\upload_00000059.
And its mime type is 
  • application/octet-stream


When the file is upload via Explorer the file exists and its mime type is PDF as expected.

Hello,

Can you share with us the code you used to save the File in the Portal. And also the JS plugin file.
