NAV client crashes when opening a page based on a SQL View

Hi all,

I have a "Worksheet" type page based on a SQL View. The worksheet has a series of filters on the page when are then applied to the view.

When I try to open the page, the NAV client immediately crashes. I found an exception file that says the following:

Type: System.FormatException
Message: Input string was not in a correct format.

Apparently there is data-format conversion issue. However, it gets strange. This page has been working OK. AND, if I save the page as a different object number, then run the NEW page, the page opens and behaves fine. I've tried deleting the Object Metadata record from table 2000000071, but that didn't prevent the problem.

Has anyone seen this? The SQL view is relatively simple, joining Item Ledger Entry, Warehouse Entry and Serial No. information - the view isn't simple enough however to be created in a Query.

Thanks

Ron
