Register fallback components

[joanromano]

We may want to add te ability to register fallback components in JSONFactory whenever there is no specified factory for a given type key.

So eg. for clusters always fallback to stacks.

But what if there is no specified factory for a given type then we should just not show the component at all?

So if we there exists a new json file which includes a new component which is not supported by an older app version it should just not show it at all.

Wait, do I get the point you mean? 😬

@ChristianOrgler if there is no default component and a given type is not registered, we will not show it. If there is a default component, we will show that default component whenever a type is not registered; the clients can choose.

I think that might be useful for component types like View, where we might want to always fallback to simple cells or simple labels with text.

[ChristianOrgler]

I would not expect such kind of behaviour. Would this be on default?

[joanromano]

@ChristianOrgler what wouldn't you expect? Sorry I am bit confused since you are commenting something from a month ago and not giving enough context :/

[ChristianOrgler]

Can you elaborate a concret usecase where a fallback component would apply?

[joanromano]

e.g show default labels whenever a specific component is not registered.
