             Summary: Editing a flow on a Disconnected Node
                 Key: NIFI-5208
                 URL: https://issues.apache.org/jira/browse/NIFI-5208
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework, Core UI
            Reporter: Matt Gilman
            Assignee: Matt Gilman


Currently, editing on a flow on a disconnected node is allowed. This feature is useful when needing to debug a node-specific environmental issue prior to re-joining the cluster. However, this can also lead to issues when the user doesn't realize that the node they are viewing is disconnected. This was never an issue in our 0.x baseline as viewing the disconnected node required the user to manually direct their browser away from the NCM and towards the disconnected node.

In 1.x, this can happen transparently with the need for the user to redirect their browser. There is a label at the top to indicate that the node is disconnected but this is not sufficient. If the user continues to with their edits, it will make it difficult to re-join the cluster without manual inventions to retain their changes.

There is a dialog that should inform the user that the cluster connection state has changed. However, there appears to be a regression that is preventing that dialog from showing. We should restore this dialog and make it confirm the users intent to make changes in a disconnected state.
