missing required classes Ext.event.Dispatcher, Ext.MessageBox and Dom.js

**fenderico** · 15 Feb 2012 6:32 AM

Hi everybody,

I've just downloaded sencha2-b2 and I've tried to execute a simple example, but when the example is executed in the phone emulator or in the browser a message is displayed saying that Ext.event.Dispatcher, Ext.MessageBox and Dom.js are missing (404 Not Found). As a result I get a blank page.

Does anybody know what I'm doing wrong? Any hint?

Thanks in advance,

Any code?

    <meta http-equiv="Content-type" content="text/html; charset=utf-8">

    <script type="text/javascript" src="sencha/sencha-touch-debug.js"></script>
      </head>

      <script type="text/javascript">        
        Ext.application({
            name: "myapp",
                  
            launch: function() {
                alert("sencha!");
            }
        });
      </script>

  <body></body>
</html>

This is a screenshot of the error.

I'm not getting those errors. Try clearing cache and trying it again.

I've already tried that, but it didn't work. Could it be something related to a missing eclipse plugin or a misconfiguration? I created the project as a phonegap & sencha touch project, including the folder where sencha source was unzipped.

TIA,

What included folders should I have in a sencha project? It seems that project was wrongly created by the IDE with a missing folders.

SOLVED.

The option to create a phonegap & sencha touch project in eclipse didn't add some directories to the sencha one. I copied the missing directories and everything worked well.

Thank you for your replies.

Cheers,

I'm getting the same error - with the same exact three missing files - when using sencha-touch.js instead of sencha-touch-debug.js:

<script src="lib/touch2-beta3/sencha-touch.js"></script>
<script src="app.js"></script>

Sencha Touch sources are in

lib/touch2-beta3/src

but the three files mentioned above are searched for in:
./src

Anything I'm missing?

Can yoou be more specific are you suggesting that you copied the Ext classes into your deplyment ? Thanks I'm getting this error and no one seems to know why the build is leaving out these three files.
