Hi,

I don'y know that this is a bug, but i made an app with viewport, in there i put 5 regions, one of them a grid and a data store:

1) The store read my records of my json, and when i connect the store to the grid and do an auto column, it does but not show the data in the grid
2) when i deploy the app the app does not open the viewport

Thanks

Elias
