alex commented on JIBX-165:
---------------------------
What about the exception message though?
Marshalling the object works, it's thrown during unmarshal.
When the jibx compiler accepts a mapping, and marshalling works on this
mapping, wouldn't exception (in some internal block of the code) being thrown
be considered a bug?
> "No unmarshaller defined for class at index " exception when defining / using

> 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
>
> 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).
