Multiple upload file with PlayFramework - file-upload

Question

I'm trying to upload multiple files at once with Play Framework, but I always get the first image for each uploaded. Here's a concrete case :
The HTML :
<form method="post" action="/upload" enctype="multipart/form-data">
<input type="file" name="image" />
<input type="file" name="image" />
<input type="file" name="image" />
<input type="file" name="image" />
<input type="submit" name="submit" value="Send images" />
</form>
The controller :
public static void upload() {
File[] images = params.get("image", File[].class);
for (File f : images) {
Logger.info (f.getName());
}
}
If I upload image1.jpg, image2.jpg, image3.jpg & image4.jpg, the Logger.info on the console will display :
image1.jpg
image1.jpg
image1.jpg
image1.jpg
The other images won't be used.
I tried with List<File> instead of File[] but it doesn't work neither.
I also saw there is kind the same question here on SO (here), that use this as an answer :
List<Upload> files = (List<Upload>) request.args.get("__UPLOADS");
But it doesn't work in the v1.2.4 of Play!.
I'm using Play v1.2.4.
Thank you really much for your help!

Answer 1

Well, I have opened a ticket at Play! Framework because it seems to be problem, and apparently, I'm not the only one to have this behavior.
I tested with the new 1.2.5, and the problem is fixed, at least with the solution I gave on the question :
public static void upload() {
File[] images = params.get("image", File[].class);
for (File f : images) {
Logger.info (f.getName());
}
}
Note: I'm using Java 7!

Use the automatic binding instead of looking in the params:
public class Application extends Controller {
public static void index() {
render();
}
public static void upload(File[] files)
{
for (File file : files)
{
Logger.info(file.getName());
}
index();
}
}
The view template:
#{extends 'main.html' /}
#{set title:'Home' /}
#{form #upload(), enctype:'multipart/form-data'}
<input type="file" name="files" />
<input type="file" name="files" />
<input type="file" name="files" />
<input type="submit" value="Send it..." />
#{/}

multi file upload with play?
public static void overviewsubmit(File fake) {
List<Upload> files = (List<Upload>) request.args.get("__UPLOADS");
for(Upload file: files) {
Logger.info("Size = %d", file.getSize());
}
}
Without the File fake argument the method will not handle multipart/form-data and you'll get an empty request.args array. If anyone knows the play/standard annotation for it, let me know :)
