While you’re debugging, Firefox is killing you’re flash player session. Here’s the quick fix:

  1. type about:config in the firefox address bar
  2. search for dom.ipc.plugins.timeoutSecs
  3. double click and change the value to -1

This will disable the hang detector that was added. It’s the same reason I don’t do any debugging in Chrome (alongside the lack of HttpFox). Sometimes a break point needs more than 10-15 seconds for me to figure out what’s going on. Check out more details here

If you have to log into a website, flex won’t keep the session info and you’ll have all kinds of trouble. Especially if you want any indication that the upload actually happened. Adobe is fully aware but doesn’t seem that interested. They blame the NPAPI (Netscape Plugin API) for the issue, but don’t reference any bugs in the Mozilla project. In fact you can search bugzilla but you won’t get any open bugs.

You’d think that a technology that’s big selling point is browser independence would actually try and be browser independent. Unfortunately only IE file uploads seem to work properly.

So, how do you workaround? Javascript!

Seth On Flex has an excellent workaround, but I had problems on my results. You see, I’d loose my connection to window.opener for some reason when I got a response back from the server. So, I used frames.

My upload function and response code from my index.template.html looks like this:

?View Code JAVASCRIPT
function showUploadComponent()
{
	var w = window.open("","ARESUploadWindow","height=100, width=600,scrollbars=no,status=no,titlebar=no,toolbar=no");
	var s = 	"<form method='POST' action='/upload' ENCTYPE='multipart/form-data' name='formUpload'>File:<input type='file' name='file' /><input type='submit' value='Upload' /></form>";
	w.document.open();
	w.document.write("<frameset rows='100%,*' framespacing='0'>");
	w.document.write("<frame name='visibleFrame' />");
	w.document.write("</frameset>");
	w.document.close();
 
	var f = w.visibleFrame;
	f.document.write(s);
	f.document.close();
 
}
 
function uploadedFile(data)
{
	getFlexApp("${application}").uploadedFile(data);
}
 
function getFlexApp(appName) {
  if (navigator.appName.indexOf ("Microsoft") !=-1)  return window[appName];
  else return document[appName];
}

Then the response from the server becomes:

?View Code JAVASCRIPT
<script language='JavaScript' type='text/javascript'>
this.parent.close();
this.parent.window.opener.uploadedFile(result);
</script>

Everything within Flex is the same as Seth’s solution:
Calling the Javascript:

?View Code ACTIONSCRIPT
ExternalInterface.call("showUploadComponent");

And registering for the return:

?View Code ACTIONSCRIPT
if (ExternalInterface.available)
{
	ExternalInterface.addCallback("uploadedFile",callbackFunction);
}
