Werner,
I am facing the same issue described in the link below
(http://www.mail-archive.com/[email protected]/msg07657.html) with Castor
1.3.2 and the 'element' method. Please note this is not about naming conflicts
but about the fact that Castor SourceGenerator generates Java classes that
don't translate well the XML element substitutability to Java.
For example, assume we have the following XSD definitions:
TypeB extends TypeA
ElemA is of type TypeA
ElemB is of type TypeB, substitutes elemA
In XML documents ElemB can substitute ElemA but in the Java code generated by
Castor the ElemB class does not inherit from ElemA class and therefore there is
no substitutability there. Here's an example where substitutability matters.
Suppose ElemParent can have ElemA as a child element:
ElemParent
ElemA
SourceGenerator creates a Java class that specifies ElemA as the type of elemA.
Now, because ElemB does not inherit from ElemA the member _elemA cannot have a
value of type ElemB, which essentially kills the substitutability in Java.
Class ElemParent
ElemA _elemA;
Could SourceGenerator be changed to product the following?
Class ElemParent
TypeA _elemA;
In this case, the class member _elemA can have a value of type ElemB because
ElemB inherits from TypeB, which in turn inherits from TypeA. I tried enforcing
this type in the bindings as illustrated below but it didn't work.
<elementBinding name="/complexType:ElemParentType/ElemA">
<member name="ElemA" java-type="somepackage.TypeA"/>
</elementBinding>
I looked at the documentation of SourceGenerator and the Castor Reference Guide
but didn't find a way to work around this problem. Should I open a bug/CR
report?
Thanks
Alex

No, it does. And there's actually quite a lot of information about this and
(possible) naming conflict problems and how to go about resolving those during
source generation in the reference guide.
Just out of curiosity, what version of Castor are you trying to use ?

Werner
