Hi ,
Your problem is known and i effectly have the same trouble. I think there's a bug ...
To use boxes in dataview and get their content, you can "bind" them with properties of your data source that you created.
For example, a box can be binded with the boolean property "State" of the data source of your HTML view. Next, it's easy to get the value (with getRootRowCursor() ...)
Ciao
