Better reporting of error when attempt to save item to adapter with a null key value.

Shane Day (Chief Technology Officer) 11 years ago updated by anonymous 7 years ago 4

As originally reported in FINANCE-30, and resolved with that issue, when a item is to be saved, and one of the key values is null, the following error is displayed:

It would be better if an explanation is given instead of a NullReferenceException.

Reassigned due to change in project ownership.

Tony, please add a message for the above case.

This has been seen on FINANCE-30 and BCE-107.

See Matthews comments on BCE-107 for an explanation of the cause of the problem and for the steps to reproduce and test.

The message will likely be in Adapter.CheckAnchorChangeOnSave, inside the entitiesToSaveKeyValues.Visit method.

Reassigned for confirmation of completion.
