----------------------------------------
Assignee: Steve Lawrence (was: Mike McGann)
> Unparse: dfdl:content/valueLength of an Array returns unexpected result
> -----------------------------------------------------------------------
>
> Key: DAFFODIL-1651
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1651
> Project: Daffodil
> Issue Type: Bug
> Components: General, Unparsing
> Affects Versions: 2.0.0
> Reporter: Steve Lawrence
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 3.5.0
>
>
> When trying to get the dfdl:contentLength of dfdl:valueLength of an array,
> Daffodil returns the length of it's parent, rather than the array. This is
> because the NodeType.Exists parameter type ends up creating a DownArrayExists
> recipe, which does not change the current node. Either we need to disallow
> getting the content/valueLength of an array and require the user to wrap the
> array in a complex type, or we need to allow it and modify/add parsers to
> store value/contentLength of an array.
> Alternatively, we maybe be able to do some magic where we get the start pos
> of the first child and the end pos of the last child and return that length.
> It's not immeidately clear if that is correct.
