I have a grid that contains cells ComboBoxCell and TextInputCell. But if I change the value in one of these cells, pressing the tab key doesn't work and doesn't take me to the next cell. The tab key works fine if I don't change the cell value.

I've determined that the reason the tab key doesn't work when a value is changed is because on the blur event, the grid is re-rendered. So all the down elements are redrawn.

I'm not sure if this is a bug or if there is a way to work around this issue.

You can see this behavior in the online GXT Explorer demo (Change the date then try tabbing, but it works fine if you don't change the date):
