All Rows Not Displaying

I have a screen which has multiple grids on it, but only one displays at a time. I have AW Tabs that determine which grid to show and then the grids are hidden/shown based upon the tab selection.
In other words, all the grids are drawn in advance, but then shown/hidden based upon user action.

The rows are populated via xml.

I have encountered a bug. When I upgraded to 2.5 it seems that the grids that are not displayed initially all end up displaying only one row...although I have learned that they do actually have the rows - when changing the displayed grid, I show an alert with the number of rows in the grid, and that number shows that there are more than just one row.

I've tried using Refresh to no avail. Anyone else know why this might happen?

As a followup, it looks as though if I have all grids visible at the start and then hide them, all the rows show up later.
If the grid is hidden when first populated, then only one row shows up when it is made visible.
This did not happen in 2.0.

In the current version the grid does not initialize correctly when you hide it display:none rule. I believe the next release should fix this.

I have a similar issue but mine has to do with resizing the grid. I use the window.resize to increase and decrease the size of the grid based on the window size. The scroll container is the correct size but some of the rows remain hidden. I am also using virtual mode for this particular grid.

easy, grid.setRowHeight(20)
