read-resource operation has no failure-description when fails to get a metric attribute value --------------------------------------------------------------------------------------------- Key: WFCORE-3682 URL: https://issues.jboss.org/browse/WFCORE-3682 Project: WildFly Core Issue Type: Bug Components: Domain Management Environment: WildFly 13 with WFLY-5603 merged. Reporter: Lin Gao Assignee: Chao Wang {panel:title=PLEASE NOTE} This issue is found when verifying the feature: WFLY-5603, which is not merged yet. I think the issue belongs to WFCORE, because it should be a general issue although I cannot find other similar cases yet. {panel} ---- When trying to run *:read-resource(include-runtime=true)* command on some managed model resources, and some runtime attributes like metrics are failed to get the value, the *failure-description* is missing from the CLI result. ---- The initial analysis is related with the *rollback-on-runtime-failure* in *operation-headers*. ReadResourceAssemblyHandler [is added into the VERIFY stage for runtime query|https://github.com/wildfly/wildfly-core/blob/4.0.0.Final/controller...] to assemble each attribute result. But if one runtime attribute of a model resource fails to get the value, the OperationContext [won't continue|https://github.com/wildfly/wildfly-core/blob/4.0.0.Final/control...] because the [current implementation|https://github.com/wildfly/wildfly-core/blob/4.0.0.Final/c...] is checking whether the *ContextFlag.ROLLBACK_ON_FAIL* exists in operation headers. But trying to put such operation header into the operation headers may lead to the whole CLI succeeds even there are failures for the runtime attributes.
