Account Schedule; errors with an unhandled exception

Loading an existing Account Schedule, as in the Opening Schedule for a Loan Account, may fail with "An unhandled exception has occurred. Primary Key does not exist in collection.".

This issue may be the result of an Account Type's "Payment" Element being changed and the Element being deleted - after an Account has been added using this Element.

To recreate, add a new Payment Received Element. Assign this to the "Payment" element under an existing Account Type (on the Accounting page). Then add a new Account and save. Next change the "Payment" element back to its original value and then delete the Element.

A change has been made so that if the Payment Element no longer exists when loading an Account Schedule, it is substituted back to the current "Payment" element defined for the Account Type.

Note, once an Account Transaction has been created using an Element the Element can no longer be deleted - so this is not typically an issue.
