Do you need to set an encoding type in the flash?

Hi,

Anyone out there with the ability to debug the wizard who is using a Mac?

This bug has been floating around now for a while now and I thought it was related to the Firefox Cookie bug but it doesn’t appear to be… and ii’ve been able to reproduce it here…

Anyway, when you try to upload media in any browser other than Safari the file is POSTed to the script upload.php and this php file tries to write the data to server disk… If you monitor the Network in the Developer Tools or Firebug then you see the file upload.php appear…

If you try to do this in Safari though then upload.php never appears so doesn’t appear to be POSTed to… if you press the little magnifying glass to preview the image then file_exists.php fires in both Safari and every other browser… strangely enough - if the file is very large then you get the progress bar which gradually increases as if the data is being sent….

Anyone have any idea why the wizard doesn’t appear to POST to upload.php in Safari?

Hi John -- not sure how I find the version of Xerte -- it's provided to us by Alastair. I'll take a look at the console when I get a chance (next week, as I'm travelling at the moment).

Hi Graham,

I’ve had a look into this and I can’t replicate it. I too am using Version 5.1.9 (6534.59.8) and it works as expected, not really sure why yours wouldn’t. Are you using v2.0 of XOT or an older version?

Also, do you see any error messages in the console  when you do this?

•         Preferences --> Advanced, Check "Show develop in menu bar"
•         Menu-->Develop --> Show Web Inspector

Hi John

I can easily replicate if I have to, but as I remember, the issue occurred when I tried to add an image to any of the pages.

Using any page template that allows you to add an image (for example the 'advanced image' page template, you click the [...] button and it opens a window that allows you to select an image file (typically JPEG or PNG). When you choose the file, a small upload progress window opens, followed by a window that says 'Success'. You can dismiss this, and the filename of the image is displayed. You can then use the magnifier icon (image inspector) to preview the image.

When using Safari (version 5.1.9), all goes as expected except that the upload progress happens too quickly. The filename appears, but clicking on the image inspector icon does not display the image -- it gives you an error that says 'you must select media before you can preview it'. Essentially, the image has not been uploaded. The screenshot attached shows the result of clicking the Image Inspector icon with an image that has been 'uploaded'.

Safari CAN preview images that have been uploaded previously on a PC, or via another Mac browser, and images 'uploaded' with Safari CANNOT be previewed with another browser, so the problem is not with the image inspector itself.

Now it has to be admitted that v5.1.9 of Safari is not the 'latest and greatest', but it's still reasonably common as the latest that can be run on the previous iteration of Mac OS X (Snow Leopard). I guess before you investigate further, you should try it out on current Safari on Mountain Lion.

Hi Graham,

Just following up on Alistair's email as I didn't get a reply, but I sent it back to the list...

I'll investigate this for you, I don't often use Safari but haven't noticed any issues when i have, although this hasn't been recently.

Can you tell me if its the upload button in the Flash wizard or the media upload button in the properties panel? And what is it that doesn't work? Do you get the file system popup? Can you choose a file? What happens once you've selected the file?

I suspect it might be session related, similar to the Firefox/Flash bug that took us a while to fix, but if it is this then it should be easy to implement a fix for Safari.

A colleague of mine has been working on this metadata LO – http://vle.jisctechdis.ac.uk/xerte/play_281

He wanted to report back an issue with Safari on a Mac. Highlighted below.

Any other Mac/Safari  users experienced this?

Hi Alistair

Just another quick report on Xerte for the developers. I found the upload functionality for images and audio does not work in Safari -- but does work in Chrome on my Mac.

Now I've finished off the LO on metadata (let me know what you think!), I might have a go with the Toolkits tool. The LO was originally written as a single HTML5 page, so might well be suited.
