> Key: NIFI-3575
> URL: https://issues.apache.org/jira/browse/NIFI-3575
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Joseph Percivall
> Assignee: Matt Gilman
> Priority: Critical
>
> When you move any component from the parent group and drag and drop it into a
> process group, if you immediately enter the process group (within
> approximately half a second) the process group will cease to exist (even if
> it had contents already).
> If the UI renders the graph initially, attempting to refreshing the canvas
> returns "Unable to locate group with id: <id of process group that died>".
