When setting up a browse dialogue and a record is returned, select the record and click okay. This takes you to the maintenance window with the selected record active. However if you now movenext etc on the one pk field update the rest of the test boxes stay as is. Did i do something wrong or is this a bug.

Ben,

Correct me if I'm wrong but I was under the impression that the OM alternate values for null was to eliminate problems where NULL data was returned from the database. In this case I'm adding a new row. Since I don't have the source for 1.41 I'm not able to step through all of the code but what I've noticed is that in the cases where I'm receiving the errors is that fileds that would automatically be set to a non null value (even if they were not configured to do so in OM) for a new row are not being set.

Check the "AllowNullValues" property on the business object and make sure it's False.  If that property is set to True, then the business object will not initialize the values within a new row.
