Required for class like Retry where they have a "type" property that we want to keep It is a bit tricky here, we must force default value if the property is required because, however, even if the property is visually filled in the input, it will not be in the javascript object that represents the task  Cast is necessary because we have now two `flatten` method with 3 params that could works with a null as a 3rd parameter There may be multiple `type` that we will need to keep, better to extract that in a dedicated method like `isTypeToKeep(entry.getKey)` I also think that if there is a class related exception we should just goes with the default (so returning null) The `onInput` method has been removed, are you sure it's correct here? This class is for the documentation but the validation should occurs on the JsonSchema so I have mixed feelings here ... Yes because we use the mixins Task that already have the `onInput` method which is the good one for this component, the  `onInput` on this component was overriding the other one. Well, I just ask to be extracted to a method, not need to create a list with one element this seems overcomplicated ;) @Skraye can you explain why it is in the documentation part and not on the jsonschema? Well, if we face another issue similar with a type property, we just need to add `Class.class` and its done If we face another issue we just nee to switch to a list and iterate over it.
KISS, don't optimize for a potential future that will never happen
Retry not handle as an object and can't be edited in task editor
### Expected Behavior

Should be able to edit retry

### Actual Behaviour

If a retry exists, it will not be displayed as an object. Also, it cannot be edited.
