Support is not full-cycle at the server - that is, there are server APIs for retrieving each file that was uploaded, but no built-in support for storing multiple files against a single DataSource field. However, you can write custom server DMI code to do something with the files - for instance, you could create multiple new DataSource records for each file via a server DMI like this below:
String fileNameStr = (String)dsRequest.getValues().get("image_filename").toString();
String[] fileNames = fileNameStr.split(", ");
List files = dsRequest.getUploadedFiles();
for (int i = 0; i < files.size(); i++) {
ISCFileItem file = (ISCFileItem)files.get(i);
InputStream fileData = file.getInputStream();
DSRequest inner = new DSRequest("mediaLibrary", "add");
Map values = new HashMap();
values.put("title", dsRequest.getValues().get("title"));
values.put("image", fileData);
values.put("image_filename", fileNames[i]);
values.put("image_filesize", file.getSize());
values.put("image_date_created", new Date());
inner.setValues(values);
inner.execute();
}
