[jboss-jira] [JBoss JIRA] (WFCORE-809) Can not parse an ObjectListAttributeDefinition of a PersistentResourceDefinition
[
https://issues.jboss.org/browse/WFCORE-809?page=com.atlassian.jira.plugin...
]
Jeff Mesnil commented on WFCORE-809:
------------------------------------
I have not been able to provide a customer parser for this type of attribute.
It seems the PersistentResourceDefinition implementation does not support to have an
attribute represented by an XML element.
The parser will look for management attributes:
* in XML attributes (and I can't represent a LIST of OBJECT in a single attribute)
* in a XML element if the attribute has an attribute group. But the XML element
representing the attribute group can not include any children XML element
Once the PersistentResourceDefinition has looked in these places for attributes, it
expects any other XML children elements to be represent children of the resources. But in
this case, a XML element would also represent the XML representation of its
"interceptors" attribute.
Can not parse an ObjectListAttributeDefinition of a

Key: WFCORE-809
URL: https://issues.jboss.org/browse/WFCORE-809
Project: WildFly Core
Issue Type: Bug
Components: Domain Management
Affects Versions: 2.0.0.Alpha6
Reporter: Jeff Mesnil
Assignee: Tomaz Cerar
My server resource defines an "interceptors" attribute:
{noformat}
public static final ObjectTypeAttributeDefinition CLASS =
ObjectTypeAttributeDefinition.Builder.of("class",
create("name", ModelType.STRING, false)
.setAllowExpression(false)
.build(),
create("module", ModelType.STRING, false)
.setAllowExpression(false)
.build())
.build();
public static final ObjectListAttributeDefinition INTERCEPTORS =
ObjectListAttributeDefinition.Builder.of("interceptors", CLASS)
.setAllowNull(true)
.setAllowExpression(false)
.setMinSize(1)
.setMaxSize(Integer.MAX_VALUE)
.build();
{noformat}
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:
