Re: [jibx-users] About mapping same structure under different names to the same class

[Dennis Sosnoski]

When you use the <value .../> elements for the references to class MA 
you're saying to serialize the instances as simple text strings, not to 
use the structure defined by the <mapping>. You need to use a <structure 
.../> reference instead to make use of the <mapping> definition.

The problem is that a <mapping> normally has an associated element name, 
while you just want to use it as a type. The latest CVS code (just 
checked in) gives a workaround for this, using a <mapping 
abstract="true" class="myclass" ...> and references of the form 
<structure name="xxx" map-as="myclass" .../>. When you do this the name 
given on the <structure> will be used with the binding defined by the 
abstract <mapping>. You'll probably need to wait a few hours for the 
checkins to make it through to the public CVS, then get a copy and build 
if you want to try this out.

This is a kludge, and in beta 4 I'm taking a cleaner approach of using a 
<template> that corresponds to an XML Schema named type (actually goes 
beyond it, in that you can define <template>s below the top level while 
in schema named types always have to be global). This is also the basis 
for the xsi:type implementation.

Hi,
The problem is
In terms of XSD, elements X and Y in complex type B (respectively) are 
of the same complex type A.
Class MA maps to the complex type A.

What would be the JiBX binding to realize this?  I have tried
<mapping name="A" class="MA">
  <value style="attribute"  name="a".../>
  <value style="attribute"  name="b".../>
  <value style="cdata"  .../>
</mapping>
<mapping name="B" class="MB">
  <value style="attribute"  .../>
   <value style="element" name="X" type="MA"/>
   <value style="element" name="Y" type="MA"/>
    ..........
</mapping>
With the above mapping, the attributes are not being set on class A 
with the following xml

<X a="asa" b="123">
      Text
</X>
<Y a="asa" b="123">
      Text
</Y>
Any clue what might I be doing wrong?
