Hi CarbonaCat,
Thanks a lot for testing it out

The underlined parts are what I was not expecting or suggestions.
1. I have updated my work copy of the /dev repository.
2. I created a new question of type "Upload file". I selected the following advanced parameters: one file of type "*.png" have to be submitted.
3. Tried to test the question alone...
However, it ends up with a 404 not found error on the following URL: "/limesurvey_dev/admin/uploader.php". Could you check it why?
You're getting a 404 error on the aforementioned URL because the uploader sits in the limesurvey_dev directory and not the limesurvey_dev/admin/ directory. It won't work on its own, as it is dependent on the survey question for all its input. Its like a template for the upload question and not a complete entitiy on its own.
4. Testing the whole survey seems to work. I'm under Google Chrome 5.0.
5. I'm uploading a file (the active icon, active.png) with a title and a comment, I click on "Upload" (Not touching to the other texts fields), there is a progress bar...
6. Then it says it worked! However, although I did upload the requested file, it didn't automatically switch to the gallery view so I had to click.
The automatically switch to gallery has not been implemented yet. But you can expect it in the coming iteration
7. YAY I CAN SEE IT
8. Trying to update title & comment... I click on Save change, but there is no confirmation if it was really saved.
Thanks for pointing it out. We will have a flash notice for all the actions in the next iteration.
9. I click on delete... it disappeared, nice!
10. Going back to the "From computer" tab.
11. Browsing file in order to upload "junk.txt"... I think it would be nice if it rejected the file as soon as I chosen a wrong one (Remember that I have chosen *.png filter).
12. I haven't filled the title and comment fields.
13. Uploading... It says it worked... filter not working yet?
Yes, the filter has not been implemented yet, I don't want to use just the file's extension for testing a file's type. There are a couple handy PHP scripts that I'm looking into for this function. But, this is something that might be delayed for a while. Also, the number of minimum/maximum files in not yet enforced.
14. Checking in the Gallery... There is a broken image frame as it tries to display the junk.txt as an image.
15. In this case, there is no any information about what the file is. I think it would be nice to put somewhere the filename...
We'll get placeholders for the various filetypes and depending on the filetype, we'll display these placeholder images in their preview. Also, it would be a good idea to display the filename, thanks for the idea
16. Closing the window and submitting the page.
We'll also get a "Save and Exit" button, and on pressing this button the modal dialog will close. So, the users won't have to explicitly click on the "cross" on the dialog's top right.
17. The *.png filter didn't work so I guess the validation is not yet fully working.
18. I checked the /upload/tmp folder... There is a really strange thing there: The two uploaded file are still there but they're empty (0 bytes)...
This doesn't sound good. Could you please give me some more information on this bug? Which OS are you using?
This is taking a good form, almost fully functional as you said...
Hopefully my feedback will help you! I think this post may be used as a test case...
Definitely CarbonaCat, the feedback is very useful and helps me identify possible issues and fix them. Thanks a lot for your time
