---------------------------------------

             Summary: 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


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.
