setMasked not displaying spinner or message

[tmgrube]

I'm displaying a loading message like this while fetching data:

Ext.Viewport.setMasked({message: 'Loading...'});

After I create my production version with the sencha app build production command, the setMasked function disables the page but no longer shows the spinner icon or the loading message. What am I doing wrong?

You should specify the xtype for the mask. This will do the job:

Ext.Viewport.setMasked({
       xtype: 'loadmask',
       message: 'Loading..'
});

sass

add this

@include sencha-loading-spinner;

Thanks. That's what I was looking for.
