[jboss-jira] [JBoss JIRA] (WFCORE-809) Can not parse an ObjectListAttributeDefinition of a PersistentResourceDefinition

[Tomaz Cerar (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13088537#comment-13088537 ] 

Tomaz Cerar commented on WFCORE-809:
------------------------------------

We don't have any convention / impl about how complex attributes should be persisted / marshaled in PRD.
for time being you will need to provide custom marshaller / persister for that attribute.

> The "interceptors" is a LIST of "class" attribute which is an OBJECT composed of a "name" and "module" attribute.
> I'm not sure what is the corresponding XML format for this attribute.
> Ideally, I'd like to have this XML format:
> {noformat}
>     <server name="default" >
>             ...
>             <interceptors>
>                 <class name="org.bar.MyInterceptor"
>                        module="org.bar" />
>                 <class name="org.baz.MyOtherInterceptor"
>                        module="org.baz" />
>             </interceptors>
>             ...
>       </server>
> {noformat}
> This XML can not be parsed and I have not found which XML representation can be parsed given my INTERCEPTORS definition.
> The XML parsing fails with:
> {noformat}
> javax.xml.stream.XMLStreamException: ParseError at [row,col]:[23,27]
> Message: WFLYCTL0377: Unexpected element '{urn:jboss:domain:test:1.0}interceptors' encountered. Valid elements are: 'buffer-cache'
