I'm having a small problem where [grid].changeDataset() appears to NOT be clearing out the previous data. When it loads with a new dataset which doesn't have some of the items from the previous dataset, the previous items remain instead of being blank.

Just as an example - If I have this as item 0 in a data array (pseudocode):
[code]
olddata = [ title: 'Title1', date: 'July 31', summary: 'This is the first one' ]
newdata = [ title: 'Title2', summary: 'This is the second one']
[/code]

At this point, the view is displaying a grid populated with olddata. When I call:
[code]
[grid].changeDataset([])
[grid].changeDataset(newdata)
[/code]

- title and summary change, but date is still displayed.
