"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
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).
