Dennis Sosnoski resolved JIBX-165.
----------------------------------
Resolution: Fixed
Fix Version/s: JiBX 1.1.5
I've added code in the binding validation to check for this case of an abstract
extends mapping which is not itself extended. I'm also clarifying the use of
extends in the documentation.
> "No unmarshaller defined for class at index " exception when defining / using
> abstract mappings

>
> Key: JIBX-165
> URL: http://jira.codehaus.org/browse/JIBX-165
> Project: JiBX
> Issue Type: Bug
> Components: core
> Affects Versions: JiBX 1.1.3
> Environment: java 1.4.2, linux
> Reporter: alex
> Priority: Critical
> Fix For: JiBX 1.1.5
>
>
> I have the following issue:
> Chain of inheritance -
> AbstractBase -> NonAbstractBase2 -> AbstractChild
> when defining mappings using
> {{
> <mapping abstract="true" class="AbstractBase">
> ...
> </mapping>
> <mapping name="non_abstract" class="NonAbstractBase2" extends="AbstractBase">
> ...
> </mapping>
> <mapping abstract="true" class="AbstractChild" extends="AbstractBase">
> ...
> </mapping>
> }}
> and trying to marshal and unmarshal a completely unrelated element (that
> shares only the AbstractBase), I get "No unmarshaller defined for class at
> index K" exception.
> I also tried the same with {{class="AbstractChild" extends="NonAbstractBase2"
> }} (in my experience, in these chains jibx is expecting the first base to
> appear in extends attribute value - otherwise it just fails to unmarshal -
> perhaps that's a bug as well), with same results.
> However, when I removed {{extends="AbstractBase" }}from AbstractChild, the
> error disappeared.
> This also does not prevent me from using {{ <structure
> map-as="NonAbstractBase2"/> }} in the AbstractChild mapping - and it
> marshalls and unmarshalls correctly (seems to, anyway). It is however very
> annoying and may have some other negative effects (like not being able to
> substitute an AbstractChild for NonAbstractBase2).
