Dennis Sosnoski resolved JIBX-169.
----------------------------------
Assignee: Dennis Sosnoski
Resolution: Fixed
Fix Version/s: JiBX 1.1.6
I've verified that the supplied binding compiles with the current CVS code,
after some earlier fixes to the name handling. The test program fails when it
tries to create an unmarshaller for the output-only binding (and I've also
corrected the error message for this case, which previously had marshaller and
unmarshaller reversed).
The problem reported by Ingo Wilken is not really an issue, since the JiBX
unmarshalling code correctly requires distinct names for each concrete
<mapping> definition. I don't know how this ever could have worked with 1.0.2,
but the only way to define multiple <mappings> with the same name now is to use
separate binding definitions. If you split your current binding into two, and
compile them in a single execution of the binding compiler, that should work.

> Just tried upgrading to JIBX 1.1.5 from 1.0.1 and hit this problem.
> I have a binding that is direction="output" and I have three hibernate
> classes that map to the same element name.
> When I try to bind compile, there is an exception thrown because the equals
> method in NameAttributes, when the name is the same, resorts to the namespace
> to distinguish the two objects, but the namespace has not been set on either
> of them.
