----------------------------------------
Assignee: Steve Lawrence
> Abort: NadaParsers are all supposed to optimize out!
> ----------------------------------------------------
>
> Key: DAFFODIL-2306
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2306
> Project: Daffodil
> Issue Type: Bug
> Components: Middle "End"
> Affects Versions: 2.5.0
> Reporter: Mike Beckerle
> Assignee: Steve Lawrence
> Priority: Major
> Fix For: 2.6.0
>
>
> I have a schema that uses this group. It's a way of doing an optional element
> using a choice-by-dispatch.
> Running this causes an abort when a NadaParser survives the optimizer and
> makes it into the parser definition.
> {code:java}
> <xs:group name="wordPadding">
> <xs:choice dfdl:choiceDispatchKey="{ if ($tns:l16WordPaddingBits eq 0) then
> '0' else '1' }" >
> <xs:sequence dfdl:choiceBranchKey="0"/>
> <xs:element dfdl:choiceBranchKey="1" name="spare" type="vmfgi:padding"
> dfdl:length="{ $tns:l16WordPaddingBits }" />
> </xs:choice>
> </xs:group>{code}
