> Key: DAFFODIL-2657
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2657
> Project: Daffodil
> Issue Type: Bug
> Components: Middle "End"
> Affects Versions: 3.2.1
> Reporter: Mike Beckerle
> Assignee: Mike Beckerle
> Priority: Major
>
> When an element has prefixed lengthKind, prefixIncludesPrefixLength='yes' the prefixLengthKind itself is derived from xs:unsignedInt and has implicit lengthKind (hence, length 4 bytes) and representation is 'binary'.
> This should work to subtract 4 bytes from the value of the prefix to get the value of the length of the content.
> However, I get this backtrace:
> {code:java}
> java.util.NoSuchElementException: None.get at scala.None$.get(Option.scala:529)
> at scala.None$.get(Option.scala:527)

> It seems to be because Daffodil is assuming there will be a lengthEv for the length of the prefix, but if the prefixLengthType itself uses lengthKind 'implicit' there will not be a lengthEv (currently).
