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.
