---------------------------------------
I had a very similar problem, possibly same cause: AXIS2-5457
> WSDL2C: incomplete code in axis2_extension_mapper.c for xsd choice type
> -----------------------------------------------------------------------
>
> Key: AXIS2-5443
> URL: https://issues.apache.org/jira/browse/AXIS2-5443
> Project: Axis2
> Issue Type: Bug
> Components: codegen, databinding
> Affects Versions: 1.6.0, 1.6.1, 1.6.2
> Environment: MacOS X 10.7.5
> $ java -version
> java version "1.6.0_37"
> Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
> Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)
> Reporter: Jürgen Keil
> Fix For: 1.5.6
>
> Attachments: bug.wsdl, bug.xml, bug.xsd, test.c

> I'm trying to build an ANSI C xml (de)serializer for an xml schema using
> axis2c and axis2.
> The xml schema contains serveral choice elements.
> The xml deserializer build by axis2 WSDL2C has problems parsing these choice
> elements.
> The root cause is missing internal choice types in the generated
> axis2_extension_mapper.c file.
> Here's an example which reproduces the problem:
> bug.xsd schema file (contains a choice element)
> --------------------------------------------------------------------------------
> <?xml version="1.0" encoding="UTF-8" standalone="no"?>
> <xs:schema xmlns="urn:axis2:choice:bug"

> --------------------------------------------------------------------------------
> The parser fails with the following error message:
> $ cat /tmp/axis.log
> [Sun Oct 28 15:15:36 2012] [error] adb_Document.c(263) failed in building adb
> object for element DocumentChoice_type0
> [Sun Oct 28 15:15:36 2012] [error] adb_Document.c(273) failed in setting the
> value for DocumentChoice_type0
> When I look at the generated axis2_extension_mapper.c file, I notice that
> there are several places
> that handle the "adb_Document" type, but the internal
> "adb_DocumentChoice_type0" type is missing.
> As soon as I manually add "adb_DocumentChoice_type0" to the generated file
> axis2_extension_mapper.c I get a working xml deserializer.
> Workaround: Use axis2 1.5.6 - the old axis2 1.5.6 WSDL2C is able to produce
> a working xml
> deserializer
