Extending classes in 4.1-PR1: what am I missing?

[tangix]

Running the following code in 4.1-PR1:

Ext.define('VTProctor.view.sites.CompanyGrid', {
    extend: 'Ext.grid.Panel',
    alias: 'widget.companygrid',

    columns: [
    {
        header: 'Name',
        dataIndex: 'company_name'
    },{
        header: 'Class',
        dataIndex: 'className'
    },{
        header: 'Customer No',
        dataIndex: 'company_customerNo'
    },{
        header: 'Territory',
        dataIndex: 'territoryName'
    },{
        header: 'Country',
        dataIndex: 'printable_name'
    },{
        header: 'Employees',
        dataIndex: 'employees'
    },{
        header: 'Website',
        dataIndex: 'company_website'
    }
    ],

    initComponent: function() {
        console.log('sites.CompanyGrid init');
        this.store = Ext.getStore('sites.Companies');

        this.bbar = Ext.create('Ext.PagingToolbar', {
            store: Ext.getStore('sites.Companies'),
            displayInfo: true,
            displayMsg: 'Displaying Companies {0} - {1} of {2}',
            emptyMsg: "No Companies to display"
        });

        this.callParent(arguments);
    }

})

In 4.1-PR1, the grid no longer shows the LoadMask and I have to manually add "loadMask: true" to the config.
In 4.0.7 the default ("true") is applied and in 4.1-PR1 the default is true (tested with the example) but it is not applied!

There must be something I am missing here... What?

[mitchellsimoens]

In our latest code which will be the nest release, I see the load mask by default.

[tangix]

As I put in my post - I have verified that loadMask = true by default, in both 4.0.7 and 4.1-PR1.

My real question was - why doesn't my extend work and set the loadMask property?

[mitchellsimoens]

Nothing sticks out to me although I never put Arrays and Objects as a property. They can sometimes be shared across instances but that shouldn't bother the load mask.

[tangix]

OK - this seems not to be a problem with the extended grid - it seems to be a problem with the run-away load masks discussed here:

My extended class works until I change tabs and then the mask is gone which caused me to think that the extend was wrong.
