Problems when Passing Business Object ByRef

Tim Dol — Tue, 06 Nov 2007 10:09:11 GMT

I have two related business objects. I have some code to add records to both business objects and when I execute this code within a form, the code runs fine and the records are added properly.

I needed the ability to share this logic with other programs so I moved my logic to the parent business object class and pass the child business object ByRef. When I execute the code, I get an error creating a new row on the child BO. (System.IndexOutOfRangeException). Index 0 is either negative or above rows count.

It seems to execute the NewRow fine and it actually sets the Fk value correctly on the child record but as soon as I try to assign something to any other field it errors out.

Any Idea's??

Thanks

Tim

I think Trent emailed you back the option that states that the BeginLoadData() prevents the DefaultView from being updated and the business object uses that view extensively.

We were finally able to recreate the problem in a test project. I emailed you guys the test project so you can replicate the index error.

Trent,

This same issue has popped up in another piece of code. We tried building a sample application to replicate for you, but of course it works fine in the sample code. I sent you any email requesting a remote session so we can show you the problem. It's kind of holding us back from finishing an important project so I would appreciate a few minutes of your time to show you the issue.

Thanks,
Tim

You can ignore this for now. There were other strange things happening on this form so I created a new form and the problem disappeared. Not sure why, but I can now create new records in the business object without any errors.
