Robert Lazarski resolved AXIS2C-1289.
-------------------------------------
Fix Version/s: 2.0.0
(was: 1.7.0)
Resolution: Fixed
- Issue: The old XSL-based WSDL2C generated deserialization code that used
position-based matching. When the first element was empty/nillable, it was
misidentified because empty elements were skipped in position counting.
- Status: Fixed in 1.7.0 for the old XSL-based generator
- Native generator: Uses name-based matching (axutil_strcmp(local_name,
"elementName")), not position-based matching. This design is fundamentally
correct and doesn't have this class of bugs.
The native generator correctly handles empty first elements because:
1. It iterates through all children with axiom_node_get_first_child +
axiom_node_get_next_sibling
2. It identifies elements by their XML name, not position
3. Empty elements (where text_value == NULL) are still recognized by name
No changes needed - the native generator's design avoids this issue entirely.

> Project: Axis2-C
> Issue Type: Bug
> Components: code generation
> Environment: Windows XP
> axis2-1.4.1-src with slight changes to the CADBBeanTemplateSource.xsl
> template to embed some minor bug fixes.
> Reporter: Catalina Caloian
> Priority: Major
> Labels: patch
> Fix For: 2.0.0

> Attachments: CADBBeanTemplateSource.xsl, XLocate.wsdl, svn.diff

> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Scenario:
> - the first element in a sequence is nillable
> - in the actual XML, that first element is present, but is empty
> - the deserialization code of the parent mishandles this element by not
> recognizing it as being its *first* child element and by treating it as if it
> were a child with position >= 2
