JBO-26044 binding a dynamic VO to a grid

Question

In my app I create a VO dynamically at runtime using a
createViewObjectFromQueryStmt(name,null), adding dynamic attributes and inserting rows.
All works but, if I bind this to a grid I get the JBO-26044 error.
In the message the system shows a "SELECT count(1) FROM (null)".
How can I solve that issue ?
TIA

Tullio:
It's a bug that's fixed in 9.0.4. What's happening is that you have a VO whose query stmt is empty and the table control is trying to get estimated row count.
To get around this problem, you should create a VO in DT to be used as the dynamic VO. Then call createViewObject(String, String), instead of createViewObjectFromQueryStmt().
In this DT-created VO, override the following method:
public long getQueryHitCount(ViewRowSetImpl viewRowSet)
and return either 0 (if you don't know the estimated row count) or the estimated row count.
Thanks.
