AttributeMarshallers.SimpleListAttributeMarshaller needs to flag isMarshallableAsElement as true

XMLWordPrintable

      I have a long string value that I want to persist the XML configuration like:

      <test>
    <x>Long string value that does not fit as attribute</x>
    <x>The element value should be more appropriate.</x>
</test>

      So I tried with

      AttributeDefinition ad = SimpleAttributeDefinitionBuilder.create("x", ModelType.STRING).build();
SimpleListAttributeDefinition attributeDefinition = SimpleListAttributeDefinition.Builder.of("test", ad).build();

      then I got:

      java.lang.UnsupportedOperationException: WFLYCTL0284: Could not marshal attribute as attribute: test
	at org.jboss.as.controller.AttributeMarshaller.marshallAsAttribute(AttributeMarshaller.java:79)
	at org.jboss.as.controller.AttributeMarshaller.marshall(AttributeMarshaller.java:95)

      Looking inside of the SimpleListAttributeDefinition, I see it uses AttributeMarshallers.SimpleListAttributeMarshaller internally which implements only marshallAsElement method, but leaving isMarshallableAsElement un-implemented which returns false by default.
