Grid with checkcolumn in viewport

[brumby007]

When i put a grid with checkcolumn in a viewport,firebug reports error: view.mainBody has no properties? Anyone knows?


viewPort = new Ext.Viewport({
layout:'border',
items:[
kGrid,
bGrid,
dGrid,
pGrid,
lGrid,
oGrid
]
});

Well, for starters a border layout can't have 6 items.

If i want to have a viewport with 6 gird in it ,which layout i can use ?

I've test many kinds of layout, but it seems that , all of them report the same error.

May be viewport can't put 6 grids in it ?
