go to post Eduard Lebedyuk · Dec 26, 2017 Class include is not required (and does not seem to affect anything) and can be omitted Include Child Why that happens, as methods generators are compiled before methods? As for the second approach, I'd like to avoid duplicating code (in a real case I have about 20 methods 1-50 lines long).

It may appear in one of future versions. I've posted a workaround.You can also check RESTForms - REST API for your persistent classes, it does support JSON (de)serialization. Another article about RESTForms.
