I take the border layout from the examples and put a grid panel into a tab,
the grid panel is not scrollable.
is this a bug or am i doing wrong?


My TabPanel:

Ext.define('MyCenterTabPanel', {
extend: 'Ext.tab.TabPanel',
alias: 'widget.tabPanel',

region: 'center',
id: 'centerpanel',
activeTab: 0,
layout: 'fit',
border: true,
autoScroll:true,
items: [{
id: 'portlet-1',
title: 'Grid Portlet',
items: new MyGridPanel(),
listeners: {
// 'activate': alert('sth') <-- this won't work either!!!
}
},{
title: 'Tab 1',
html: 'A simple tab'
}]

});



My Grid Panel (from the examples):


Ext.define('MyGridPanel', {

extend: 'Ext.grid.GridPanel',
alias: 'widget.gridportlet',

You are overnesting your panels.. GridPanel is a panel and therefore can be put directly in the TabPanel. You can either hoist the grid up to be a direct child of the tab or you can add a layout of fit to the additional panel you've placed in the tabpanel.
