ValuesAllowed does not allow empty value

[ValsorimS]

Please include the following with each issue:

1. Describe the bug We are converting functionality from NAV2009, where the ValuesAllowed property on the form was set to "";A;N for the Code[1] field. When I set the same property in BC22 or BC23 to '', 'A', 'N'; and I delete a value in a field, I get an error: "Value '' is not a valid value. The following values can be used: ;A;N."

2. To Reproduce Just add a field of type Code[1] to the page and set the ValuesAllowed property.

field(ValuesAllowedBug; Rec.ValuesAllowedBug)
                {
                    ToolTip = 'Specifies the value of the ValuesAllowedBug field.';
                    ValuesAllowed = '', 'A', 'N';
                }

3. Expected behavior I expect that it will be possible to delete the value in the field when there is a value '' in the ValuesAllowed.

4. Actual behavior Type A in the field and delete it. And you get an error: Value '' is not a valid value. The following values can be used: ;A;N.

5. Versions:

• AL Language: v12.1.887908
• Visual Studio Code: 1.84
• Business Central: BC23, BC22
