Object function has no method defer

I'm try to render a progress bar in grid (Ext JS), and get this error:

Object function has no method defer

What is this "magical" method? What does it do? And why is it not found? Code:

renderer: function (value, meta, rec, row, col, store){
    var id = Ext.id();
    (function(){
        new Ext.ProgressBar({
            renderTo: id,
            value: 0.5
        });
    }).defer(25);
    return '<span id="' + id + '"></span>';
}
Solution

  • The function defer is used to delay a function call by X milliseconds. Try a syntax like this:

    Ext.Function.defer(function(){
    new Ext.ProgressBar({
        renderTo: id,
        value: 0.5
    });
}, 25);

    That should work according to ExtJS API documentation.
