I had a very similar problem, possibly same cause: AXIS2-5457

> 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)

> 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
