I am currently playing with the Pivot Grid and have come accross the following anomoly...

My current set up for my page is:

<div>
Ext.Panel (type border) {
West: Ext.DataView
center:
Ext.Panel {
Item 1: Ext.DataView
Item 2: TabPanel {
tab 1: Ext.Panel (type border)
West: Ext.DataView
Center: columnchart
South: Ext.grid.PivotGrid (A)
tab 2: Ext.Panel (type border)
West: Ext.DataView
Center: Ext.grid.PivotGrid (

}
}
}
</div>

I have found that the pivot grid ( on tab 2 does not display any row/column headers. If I swap tab 1 and 2 around they appear. But pivot grid (A) loses its headers.

All data is supplied via an asmx webservice using Ext.data.JsonStore
