[4.2.0-489] Ext.Component - setLoading generates error

[utkarshgaur]

I tried to update my app from 4.1 to 4.2.0-489 and a basic function - setLoading causes my app to crash.

Sample code to reproduce error:

Code:

    var w = Ext.create('Ext.window.Window', {
        height : 400,
        width : 400,
    }).show();
    
    w.setLoading(true);

Output:
ext-all-debug.js:39929 : Cannot call method 'mask' of null

Expected Output:

A loading mask on the window.

I can't reproduce this. I copied your code exactly against the 4.2.0-489 build, no errors and I see the mask show up. All I did was replace the contents of array-grid.html with your code, inside of an onReady block:

Ext.onReady(function() {

    var w = Ext.create('Ext.window.Window', {
        height: 400,
        width: 400
    }).show();

    w.setLoading(true);

});

Sorry, someone in my team had overwritten the LoadMask class which was breaking. I'll delete this thread. Thanks for the quick reply though!
