import.sdo element is not resolved if it follows a property element
-------------------------------------------------------------------
Key: TUSCANY-1949
URL: https://issues.apache.org/jira/browse/TUSCANY-1949
Project: Tuscany
Issue Type: Bug
Components: Java SCA Assembly Model
Affects Versions: Java-SCA-1.0
Reporter: Greg Dritschler
Priority: Minor
I have an SCA composite that uses both a property element and an import.sdo
element. If the property element appears before the import.sdo element as
shown below, then the application fails during execution when it tries to
create an SDO.
<composite ...
<component ...
<property name="p" type="xsd:string">XYZZY</property>
</component>
<dbsdo:import.sdo .../>
</composite>
If I reorder the elements as shown below then the application works.
<composite ...
<dbsdo:import.sdo .../>
<component ...
<property name="p" type="xsd:string">XYZZY</property>
</component>
</composite>
I found the problem in CompositeProcessor. When a property element is found,
it calls a method readPropertyValue. This method consumes the property end
element so CompositeProcessor won't see it. Since CompositeProcessor does not
see the property end element, it does not clear the "property" method variable.
Then when it processes the import.sdo element, it sees the "property" variable
is non-null and mistakenly associates the import.sdo extension with the
property instead of with the composite.
I was able to work around the problem by clearing the property variable after
the readPropertyValue call as shown below. (There are actually two such calls,
one for component level and one for composite level, and I cleared it in both
cases.)
// Read the property value
Document value =
readPropertyValue(property.getXSDElement(), property.getXSDType(), reader);
property.setValue(value);
composite.getProperties().add(property);
property = null; // **WORKAROUND**
