> Key: SLING-4178
> URL: https://issues.apache.org/jira/browse/SLING-4178
> Project: Sling
> Issue Type: Bug
> Components: API
> Affects Versions: API 2.8.0
> Reporter: Konrad Windszus
> Assignee: Konrad Windszus
> Fix For: API 2.10.0
>
>
> Currently the {{ValueMapDecorator}} will never return {{null}} in case type
> conversion fails and an array type was requested.
> This is neither the case if the underlying map did not contain multiple
> values (and it was converted a single element array), nor if the underlying
> array was of a different (incompatible) type.
> For the first case a single element array with value null is returned, for
> the second case an array is returned which only contains null values (as many
> as original values).
> I would propose the following change:
> # if array was requested and underlying data is an array: return null instead
> of array with null items if no item could be converted to the requested array
> type.
> # if array was requested and underlying data is an array: only return those
> items which could be converted to the requested type (leave out the others)
> # if array was requested and underlying data is not an array: return null if
> value could not be converted to the requested array type.
> This should still be in sync with the behaviour described in SLING-662.
