Cells Expand, Alignment issues in Listgrid - smartGWT 4.0 / GWT 2.4

Hi,

Our application was recently upgraded from
GWT 2.0.3 --> GWT 2.4 and
smartGWT 2.2 --> smartGWT 4.0

We have encountered issues in listgrid where certain rows have expanded to greater heights than what was expected leading to mis-aligned rows. this was not the behavior earlier to the upgrade.

Also two values that spans across 9 and 4 rows respectively in their column of the grid are not getting rendered after the upgrade.

Note: These two columns are being rendered inside the overidden "createRecordComponent()" method.

The listgrid parameter "setShowRecordComponentsByCell()" , if set to true is rendering those two spanning column values but is causing issues with cell expansion leading to mis-aligned rows

When the same parameter is set to "false", the screen is being rendered without any cell height issues but is not rendering the spanning column values.

We are trying to get those two column values which spans across multiple rows to be rendered in the screen having the above mentioned parameter as "False"

Please help us by providing any solution that could help or provide an alternative.

Thanks.

PS : could not post code or screenshot due to confidentiality
