Summary0000423: Encode/Decode of empty record
DescriptionCurrently there are three operations on RecordValue within TCI: getField, setField, and getFieldNames. There is however no operation that allows an empty record to be encoded/decoded. It should be also possible to encode/decode empty records. This extension is particularly helpful for quick-testing TTCN-3 code.

Empty records are not handled in TCI, but can be specified in TTCN-3. (part 6: 7.2.2.2.11, part 1: 6.3.1.0)
Steps To Reproduce
Additional InformationProposed Solution:
There should be one more operation that initializes an empty record of a certain "type" of data.

Provider to clarify if CreateNewInstance solves the problem

If a record type does not contain any fields, then obviously it is not possible to set a field to a specific value, nor set a field to be absent or present.

But if a value of such a type is created, then it is uninitialized (see explanation of newInstance(), clause 7.2.2.1.).

This means there is no means to create an initialized value of an empty record type. Hence, none can be used for encoding/decoding.

I suggest to extend the TCI such that newly created instances of empty record and set types are considered initialized. Either a note could be added to the definition of newInstance() or to clause 7.2.2.11.

Creating 'empty' records of arbitrary record types is not considered a good solution as mandatory fields would still have to be uninitialized.

The resolution is using already the updated text from CR2000 and CR2146.
