Looks to me like that _blank is being accessed after upload.php has returned a result (onLoad) but then not sure what the line:
wizard.getURLHelper.getURL(wizard.nfoObject.wizard.runtime, "_blank", "POST");
is doing since it is still referencing POST also...
Not really sure where we go with this or whether we even spend a lot of time trying to fix it... is a high enough proportion of people using Safari?
If you have time and want to still in a few debug statements then I'll take another look at it. Can you send data to the console easily from Flash? Just stuff like "File sent", "onLoad fired" "Returned data:..." or whatever you think would help...

It's done like this:
if(!xerte){
if(_root.read_and_write=="true"){
var result_lv:LoadVars = new LoadVars();
var send_lv:LoadVars = new LoadVars();
send_lv.filedata = wizard.xmlStr;
send_lv.filename = wizard.fileName;
send_lv.fileupdate = update; //update the play_XXX file or not?
send_lv.filesize = wizard.xmlStr.length;
send_lv.sendAndLoad(_root.savepath, result_lv, "POST");
results_lv.onLoad = function(success:Boolean){
wizard.createEmptyMovieClip('getURLHelper', 9999);
wizard.getURLHelper.data = KOData.format();
wizard.getURLHelper.getURL(wizard.nfoObject.wizard.runtime, "_blank", "POST");
}
}
}else{
The _blank is for the preview window (I think?)

Hmm interesting. Anyone know if this is the likely cause? Does the wizard post the data to a _blank target?
Can this easily be changed to post somewhere else, possibly a hidden iframe or new window?

Subject: [Xerte-dev] Mac Safari browser bug
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.

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.
