Error with formView linked to ObjectDataSOurce that returns no data

Greetings all

I have a FormView, linked to an ObjectDataSource that gets it's data from a method in the business layer, which calls a stored procedure. This works fine. I then changed the stored proc, so that NO data is returned, for further testing.

The app falls over, complaining of an out of bounds index (see Error message and Page Source attached).

Any thoughts?


In advance, thanks!!!

how did you change the stored proc? does it now return an empty resultset or does it just return out of the stored proc without returning any data? You'll need at least an empty resultset for the page to work ok I think.

Exception:  is not a valid value for Int32.
You're trying to store a value to an int that is not an int somewhere.

I think it's line 137:

<asp:QueryStringParameter Name="CoupleId"   DbType="Int32" Direction="Input"  />
