[ https://issues.jboss.org/browse/WFCORE-1577?page=com.atlassian.jira.plugi... ] Brian Stansberry commented on WFCORE-1577: ------------------------------------------ The problem is in DeploymentHandlerUtil.undeploy, which is written as if it is only called from an op targeting a deployment resource, but DeploymentFullReplaceHandler invokes it from the root resource. It takes the resource at the op address and removes all the subsystem children. This fails if neither the server-group/deployment add op nor the full-replace-deployment op have the "enabled" param defined, or if the former has it defined as "true" and the latter as "false". Those are the combinations that result in DeploymentHandlerUtil.undeploy being invoked. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
