Error with buffered grid on Ext.tab.Panel

Hi,



I have two buffered grid on Ext.tab.Panel. I need to move some rows from one grid to other.

If application layout is rather complicated, try to move is failed with error:

Uncaught TypeError: Cannot read property 'insertSibling' of null
from the extjs:

all.last().insertSibling(nodes, 'after', true);



If disable buffered render for grids - all works fine.

If put buffered grids to Ext.panel.Panel - all works fine.

2. click to Id for sort by Id the Grid1


3. select Grid2


4. click to Id for sort by Id the Grid2


5. select Grid1


6. click to any row
