XMLwriter drops namespace for datatype properties
-------------------------------------------------
Key: TUSCANY-3597
URL: https://issues.apache.org/jira/browse/TUSCANY-3597
Project: Tuscany
Issue Type: Bug
Components: C++ SDO
Affects Versions: Cpp-M2
Reporter: Thomas Gentsch
Attachments: schema1.xsd, schema2.xsd, SDOXMLWriter.cpp-PATCH
When defining XSD and XML data as attached, the resulting XML is wrong if
loaded and saved.
For datatype properties with imported NS, the NS is lost if that NS is not used
with at least one object property.
Example (prop3):
In:
==========
<?xml version="1.0" encoding="UTF-8"?>
<ns1:class1 xmlns:ns1="http://ns1"; xmlns:ns2="http://ns2";>
<ns1:prop1>bla</ns1:prop1>
<ns1:prop2>
<ns2:prop3>blub</ns2:prop3>
</ns1:prop2>
</ns1:class1>
==========
Out:
==========
<?xml version="1.0" encoding="UTF-8"?>
<class1 xsi:type="tns2:class1" xmlns:tns2="http://ns1";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<tns2:prop1>bla</tns2:prop1>
<tns2:prop2>
<prop3>blub</prop3>
</tns2:prop2>
</class1>
==========
Reason is, that the XMLWriter at the beginning collects all referenced NS by
traversing through the entire SDO, but it skips
datatype props.
The fix has some performance (must compare also the NS of all datatype props)
impact but I could not see a better way ...
