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:
HTML Code:
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):

HTML Code:
Ext.define('MyGridPanel', {
    
    extend: 'Ext.grid.GridPanel',
    alias: 'widget.gridportlet',
