Here is my problem – I’m trying to write a self-updating application, but I keep getting an error saying that runtime.air.update.ApplicationUpdaterUI() does not return a constructor.

Here’s the relevant section of the code; there are other javascript files being included, but I don’t think that any of them would be actively breaking AIR itself.

<html> <head> <script type='text/javascript' src='./js/AIRAliases.js'></script> <script type='text/javascript' src='./js/jquery-1.3.1.js'></script> <script src='ApplicationUpdater_UI.swf' type='application/x-shockwave-flash'></script> <script>     $(document).ready( function() {         var appUpdater = new runtime.air.update.ApplicationUpdaterUI();  // line 64 in this example     } </script> </head> <body> ... stuff ... </body> </html>

And the error that I get when I test it is

     TypeError: Value  is not a constructor. Cannot be used with new.      at app:/index3.html : 64      at app:/js/jquery-1.3.1.js : 2912      at app:/js/jquery-1.3.1.js : 686      at app:/js/jquery-1.3.1.js : 2916      at app:/js/jquery-1.3.1.js : 2936

  1. Verify the path in that script tag for the SWF, I’m guessing you do not have the reference to the ApplicationUpdater_UI.swf correct.

    Air is basically complaining that it cannot find a runtime.air.update.ApplicationUpdaterUI() method to call anywhere, which likely means it can’t find the SWF (or I suppose it’s possible the SWF is corrupted).
