[Validation / view models / page lifecycle series] Can't make ModelState server validation work when it happens in async method in parent VM of VM that posts back to server

I think that’s what [Bind(Direction.None)] (or JsonIgnore) does, or I don’t understand this request

[Bind(Direction.None)] does not avoid DotVVM creating a duplicate of the VM of the property and does not avoid double execution of its Load() etc. handlers.

as stated here:

@exyi

Yes, we call the nested Load/Init/PreRender on all properties, regardless if they have Bind(None). The justification being that it’s usually much easier to deal with the Load being called multiple times than it not being called at all.

I will try with JsonIgnore…
