Can not reuse view?

[desp]

Hello,
I have a form view and need it to render into two places: tabpanel and modal window. Firstly I got bunch of 'registering same id' problems so I get rid of all hardcoded id names, and after that with no error window shows up empty while it is seen in my tabpanel. By the way this view is going to be used by two controllers.

My window looks like:

Ext.define('AC.view.service.MuxFormWindow', {
    extend: 'Ext.window.Window',
    alias: 'widget.muxformwindow',
    requires: ['AC.view.mux.Form'], // i thought it would help

    title: 'Custom settings',
    height: 400,
    width: 500,
    layout: 'fit',
    modal: true,
    autoShow: true,
    items: [
        {
            xtype: 'muxform', // that my form's alias
            border: false
        }
    ]
})

Sorry, I got mistake, it's working. But I have few more questions:
1) how to hide certain form's fieldset in my window view code?
2) how to query this form and handle it's events from window but not from tabpanel? I mean how to remove ambiguity when selecting view from different controllers?

1) at instantiation or at run time?

2) Use a more specific selector : 'muxformwindow muxform'
