> newVariableInstance does not use external values when defaultValue is not
> defined
> ---------------------------------------------------------------------------------
>
> Key: DAFFODIL-2481
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2481
> Project: Daffodil
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Steve Lawrence
> Priority: Major
> Fix For: 3.1.0
>
>
> Regarding newVariableInstance and defaultValue, the spec says:
> {quote}
> If the instance is not assigned a new default value then it inherits the
> default value specified by dfdl:defineVariable or externally provided by the
> DFDL processor.
> {quote}
> Daffodil does not support the "or externally provided" part of this. If NVI
> does not provide a defaultValue, then we always use the defaultValue
> specified by the defineVariable, regardless if it was set externally.
> For example, say we have this schema:
> {code:xml}
> <xs:annotation>
> <xs:appinfo source="http://www.ogf.org/dfdl/";>
> <dfdl:format ref="ex:GeneralFormat" />
> <dfdl:defineVariable name="var1" type="xs:int" defaultValue="1"
> external="true" />
> </xs:appinfo>
> </xs:annotation>
> <xs:element name="root">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="beforeNVI" type="xs:int" dfdl:inputValueCalc="{
> $ex:var1 }" />
> <xs:sequence>
> <xs:annotation>
> <xs:appinfo source="http://www.ogf.org/dfdl/";>
> <dfdl:newVariableInstance ref="ex:var1" />
> </xs:appinfo>
> </xs:annotation>
> <xs:element name="afterNVI" type="xs:int" dfdl:inputValueCalc="{
> $ex:var1 }" />
> </xs:sequence>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> {code}
> So the "var1" variable defaults to "1", and newVariableInstance does not
> provide a default value.
> If we run the following to parse with an externally set value of 2:
> {code}
> daffodil parse -Dvar1=2 ...
> {code}
> Then we get the resulitng infoset:
> {code:xml}
> <root>
> <beforeNVI>2</beforeNVI>
> <afterNVI>1</afterNVI>
> </root>
> {code}
> Which isn't correct. Because var1 was set externally to 2, the NVI should use
> that value as the default, so both beforeNVI and afterNVI should have a value
> of 2.
