Dropdown - Value cannot be null error

Article # 3039427 - Page views: 18

Issue

Error saving field changes. Value cannot be null.
Parameter name: changes
If you need technical assistance, reference action....

 

Cause

In essence, there are 2 CURRENCY_SAPConfirmFieldAction actions executing at the same time (one from the Selection Changed event and one from the Field Confirmed event - when you press enter). In one of the actions there has been no changes made hence the error.

 

Solution

This is now register as Bug 1776099: Dropdown ConfirmFieldAction error - Value cannot be null. Parameter name: changes

However there is a workaround:

Add a SamePage action between the SaveChanges and the ConfirmFieldAction on the Selection Changed event:

OrderOfActionsThe SamePage1 SamePage1 action is just an empty SamePage action. To add an empty SamePage action just configure it like so:

EmptySamePage
