> abort when external variable has no namespace
> ---------------------------------------------
>
> Key: DAFFODIL-2588
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2588
> Project: Daffodil
> Issue Type: Bug
> Components: Front End
> Affects Versions: 3.1.0
> Reporter: Mike Beckerle
> Priority: Major
> Fix For: 3.2.0
>
> Attachments: external_var_schema_error.xsd
>
>
> Reported by a user:
> I found a problem in Daffodil 3.1.0 using external and not-external variables
> when specifying the external variable without namespace.
> Using attached schema:
> daffodil parse –s external_var_schema_error.xsd –Dexternalvar=1 dummyfile
> The below error is given.
> It does not happen when specifying namespace with the externalvar on the
> command line.
> Though I don’t know Scala, looking at VariableMap1.scala:464, it seems to me
> the “vTable.map” expects all items to be mapped, while the “if .. external”
> only maps the external variables, causing the below error for non-external
> variables. I guess it needs a filter operation before the “map” to first get
> the external variables, then “map” to get the globalQName.
>
> For us the use of the external variable name without namespace is useful,
> because we use it in several schema in the same way, and pass in the value at
> run-time. Not having to know the namespace of the schema being used makes it
> much easier for the user and our code.
