I have an app that uses a Tab layout with the same grid panel shared as an xtype widget between each form panel bound to each tab.
My Main tab layout is as follows:
Ext.define('cardioCatalogQT.view.main.Main', {
extend: 'Ext.tab.Panel',
xtype: 'main-view',
controller: 'main-view',
requires: [
'cardioCatalogQT.view.main.MainController',
'cardioCatalogQT.view.main.MainModel',
'Ext.ux.form.ItemSelector',
'Ext.tip.QuickTipManager',
'Ext.layout.container.Card'
],
style: 'background-color:#dfe8f5;',
width: '100%',
height: 400,
layout: 'vbox',
defaults: {
bodyPadding: 5
},
items: [{
title:'Main',
region: 'south',
xtype: 'form',
itemId: 'Ajax',
flex: 1,
styleHtmlContent: true,
items:[{
xtype: 'image',
src: 'resources/images/R3D3.png',
height: 50,
width: 280
},{
title: 'Ad Hoc Sandbox for Cohort Discovery'
}] ,
lbar:[{
text: 'Initiate advanced request',
xtype: 'button',
handler: function(button){
var url = 'https://url_here';
//cardioCatalogQT.service.UtilityService.http_auth(button);
window.open(url);
}
}]
},
/*{
xtype: 'resultsGrid'
//disabled: true
},*/
/*{
xtype: 'searchGrid'
//disabled: true
},*/
{
xtype: 'demographicGrid'
//disabled: true
},
{
xtype: 'vitalGrid'
//disabled: true
},
{
xtype: 'labGrid'
//disabled: true
},
{
xtype: 'diagnosisGrid'
//disabled: true
},
{
xtype: 'medicationGrid'
//disabled: true
},
{
xtype: 'procedureGrid'
//disabled: true
},
{
xtype: 'queryGrid'
//disabled: true
}
]
});
The individual tabs that share the same grid widget (specifically, demographicGrid, vitalGrid, labGrid, diagnosisGrid, procedureGrid and medicationGrid, each referenced by xtype in the main view) look like:
/**

The only difference between each of the form panels in the tabs are the item components. Each of these form panels references an xtype of 'searchGrid' and renders it like in the attached image:
The problem is that I have 6-instances of this same grid. This works for the most part, but it is causing some issues related to getting control of the checkboxes in my grid along with some bizarre grid store load behaviors, and honestly, keeping track of components using this anti-pattern is a PITA.
I would like to somehow have a single instance of my searchGrid in a lower vertical panel, while an upper vertical panel has the item components I need to change according to the requirements for each tab. An example of how the item controls vary is 
My desired behavior is that when I click on a tab, the upper item components would take me to a different form panel, while the lower panel stay fixed on the search grid.
However, I currently have the searchGrid bound to each tab's form panel, since that is the only way I could get this to work.
The searchGrid grid panel looks like:
Ext.define('cardioCatalogQT.view.grid.Search', {
extend: 'Ext.grid.Panel',
xtype: 'framing-buttons',
store: 'Payload',
itemId: 'searchGrid',
requires: [
'cardioCatalogQT.view.main.MainController'
],
columns: [
{text: "ID", width: 50, sortable: true, dataIndex: 'id'},
{text: "Type", width: 120, sortable: true, dataIndex: 'type'},
{text: "Key", flex: 1, sortable: true, dataIndex: 'key'},
{text: "Criteria", flex: 1, sortable: true, dataIndex: 'criteria'},
{text: "DateOperator", flex: 1, sortable: true, dataIndex: 'dateComparatorSymbol'},
{text: "When", flex: 1, sortable: true, dataIndex: 'dateValue'},
{text: "Count", flex: 1, sortable: true, dataIndex: 'n'}
],
columnLines: true,
selModel: {
type: 'checkboxmodel',
listeners: {
selectionchange: 'onSelectionChange'
}
},
// When true, this view acts as the default listener scope for listeners declared within it.
// For example the selectionModel's selectionchange listener resolves to this.
defaultListenerScope: false,
// This view acts as a reference holder for all components below it which have a reference config
// For example the onSelectionChange listener accesses a button using its reference
//referenceHolder: true,
// inline buttons
dockedItems: [{
xtype: 'toolbar',
dock: 'bottom',
ui: 'footer',
layout: {
pack: 'center'
}
}, {
xtype: 'toolbar',
items: [{
//reference: 'andButton',

}
});
I messed around with using a Vbox layout to get my desired behavior, but was rather unsuccessful. This does not seem like that uncommon of a use case to have an upper Vbox panel change to different form panels based on a Tab click, while the lower Vbox panel remains fixed. Any insight would be most welcome.
