EXT is not defined error!!

[cahello]

Hello All,

I get this error "Uncaught ReferenceError: Ext is not defined" followed by some indication towards .js files. I have a portlet's view.jsp which calls the main.js by "Ext.onReady(function(){ sample3();})". The main.js has links to two other .js files, namely panels.js and panels2.js. The code for one of the .js files is as follows:

Ext.application({
launch: function() {
Ext.define('trial', {
extend:'Ext.panel.Panel' ,
id:'trial',
items :[{
xtype : 'button',
text: 'Submit'
} ],
height: 200,
width: 400
})
}
});

The code for the other one is similar. On trying to display, it gives the error "EXT is not defined". I cant seem to find out the reason even after a lot of searching. Any suggestions?

Thanks in advance!

Do you included ExtJS in your HTML file?

ex:

    <link rel="stylesheet" type="text/css" href="extjs4/resources/css/ext-all.css"/>
    <script type="text/javascript" src="extjs4/ext-all-debug.js"></script>

Regards,
Scott.

Yep. I have included both the files. I have also included ext-all.js.

Are there any errors in the console when trying to load? cannot find ext-all.js error?
If you feel the path is right, are you using any dynamic loaders?

The path is correct because there was no error initially. Only after I added the line "console.log("Blah");", I started getting the issue. Each time I restart the server, I get a different error. Now, I am getting this error:
"Uncaught TypeError: Cannot read property 'dom' of null" for "ext-all-debug.js".

That is a rendering issue .. does this run?

Ext.application({
    launch: function() {
        Ext.define('trial', { // define panel
            extend: 'Ext.panel.Panel',
            items: [{
                xtype: 'button',
                text: 'Submit'}],
            height: 200,
            width: 400
        });
        
        Ext.create('trial', { // create panel
            renderTo: Ext.getBody()
        });    
    }
});​

I ran it once using the modified code. It runs perfectly now without any error. Although no error exists, could you please explain why this "ext is not defined" error occurs? I have come across the same error many times before and after some random code modification, it worked. Is there any specific cause other than the path issue?

Thanks!
