What is the current behavior?

SurveyKo.Serializer.addProperty('itemvalue', { name: 'weight', type: 'number', default: null });

is not adding a property called 'weight' to the rows of a matrix question.

What is the expected behavior?

The properly should be added. On version 1.7.3 there's no problem but on 1.8.4 the custom property isn't added.

This is how it should look like:

@Tri125 It works fine for me. Here is the example.

Thank you, Andrew

Thank you, I think I will spend more time getting a minimal reproduction case as it clearly works in your example.

I think this is no longer relevant (since we have editor v2 which is a total rewrite)
