How to disable LoadMask on GridPanel

Question

I've a GridPanel which is updated every 10 seconds.

var refreshEnvironmentsStoreTask = {
    run: function() {
        this.getEnvironmentsStore().load()
    },
    scope: this,
    interval: 10000 //10 second
}
Ext.TaskManager.start(refreshEnvironmentsStoreTask);

As result of frequent updates on the grid appears flicker. I want to disable LoadMask but next code doesn't work:

Ext.define('MyGrid' ,{
    extend: 'Ext.grid.Panel',
    store : 'Environments',
    viewConfig: {
        loadMask: false
    }
});

Since the OP never shed any light on this and I was looking for it today, the answer is that this will work in versions of ExtJS after 4.01. I am using it now:

Ext.define('MyGrid' ,{
    extend: 'Ext.grid.Panel',
    store : 'Environments',
    viewConfig: {
        loadMask: false
    }
});

Have you tried creating a simple page and disabling it there before doing it on your page? It seems your setting the default which is false to false.

Ext.LoadMask

Ext.ComponentLoader

Thanks for response. I've already found solution. This is a extjs 4.0.1 bug. – Somatology
