Error 'targetContext is undefined' while using 'fieldset'

[Supriya Kale]

Hi,

I am trying to use 'fieldset' but as soon as I set the 'collapsed' property to ' true' I get error 'targetContext is undefined' in Container.js at 'frameInfo = targetContext.getFrameInfo()'.
Do we need to set something else too?

Please find my code below:

{
                        xtype:'fieldset',
                        checkboxToggle:true,
                        name:'shouldAllowPasswordProtecteInvites',
                        id:'shouldAllowPasswordProtecteInvites',
                        title: 'Password protected invites',
                        collapsed: true,
                        disabled: true,
                        items:[{
                            xtype:'form',
                            items:[
                                {
                                    xtype:'textfield',
                                    inputType: 'password',
                                    name:'invitePassword',
                                    fieldLabel: 'Enter Password'
                                },
                                {
                                    xtype:'textfield',
                                    inputType: 'password',
                                    fieldLabel: 'Renter Password'
                                }
                            ]
                        }]
                    
                }
