For Ext JS 4.1.1 this works:

Ext.define('com.ideas.widgets.Base', {
    override : 'Ext.form.field.Base',
    initComponent : function()
    {
        if(this.allowBlank!==undefined && !this.allowBlank)
        {
            if(!this.labelSeparator)
            {
                this.labelSeparator = "";
            }
            this.labelSeparator += '*';
        }
        this.callParent(arguments);
    }
});
