@Inject
private FileMultiUploadField uploadFieldRemark;
uploadField.addQueueUploadCompleteListener(queueUploadCompleteEvent -> {
int index = transactionA.getResultImageList().stream().filter(e ->(e.getRemark()!=null && e.getRemark().equals("Required")) && e.getDeleteFlag().equals(false)).collect(Collectors.toList()).size();
for (Map.Entry<UUID, String> entry : uploadField.getUploadsMap().entrySet()) {
index++;
if (index <= UPLOAD_IMAGE_MAX) {
UUID fileId = entry.getKey();
String fileName = entry.getValue();
FileDescriptor fileDescriptor = fileUploadingAPI.getFileDescriptor(fileId, fileName);
if (Boolean.TRUE.equals(checkImageExtension(fileDescriptor.getExtension(), fileDescriptor.getSize()))) {
addImage(fileDescriptor, fileId, index, "Required");
}
}
}
uploadField.clearUploads();
});
uploadField.addFileUploadErrorListener(queueFileUploadErrorEvent ->
notifications.create().withCaption("File upload error").show()
);
