ListGrid:saveAllEdits Unable to get property 'getProperty' of undefined or null refer

[Oleg]

I have a several tabs. One of them has a ListGrid. ListGrid by default initialised with 1 new row so I don't need switch to this tab before save.

When I call ListGrid.saveAllEdits() get this error:

(TypeError) @com.smartgwt.client.widgets.grid.ListGrid::saveAllEdits()([]): Unable to get property 'getProperty' of undefined or null reference

If I call ListGrid.saveAllEdits() after tab has been selected it works fine.

Can you fix this bug?
