[one-users] XML-RPC API 2.0 host.delete return value

[Daniel Molina Aranda]

Hi,

You are right, there is a typo in the documentation, because when the call
succeeds the second component of the array is not returned. The
documentation should be:

"OUT     Boolean         true or false whenever is successful or not
OUT      String  if an error occurs this is error message, otherwise it does
not exist."

instead of,

"OUT     Boolean         true or false whenever is successful or not
OUT      String  if an error occurs this is error message, otherwise it is
null."

We have already modified it in the documentation [1]

BTW, we are thinking about modifying it to return null, so that all the
calls return the same number of components in the array. But we would like
to know the opinion of the community about this issue, specially those ones
that are developing tools using this API. If the community aproves this
change we can include it in the 2.2 release.

Any comment or feedback would be appreciated.
