On the page describing how to work with different property types in config interfaces - Property Types - CUBA Platform. Developer’s Manual - it’s mentioned that Stringify classes are needed, and that some exist, but they’re not really discussed in the level of detail needed.
For example, when talking about the IntegerListTypeFactory the documentation should mention that the factory should be paired up with an IntegerListStringify otherwise problems ensue. I had to infer this, and it wasn’t too difficult to figure out but the point of documentation is to avoid making people figure things out.
