> For NiFi 2.8.0 there was the fix
> [NIFI-15366|https://issues.apache.org/jira/projects/NIFI/issues/NIFI-15366?filter=allissues&orderby=created+DESC]
> regarding nested NiFi Flows (stored in NiFi Registry). The behaviour is
> better, but there is still a GUI display bug in "Versions" -> "Show Local
> Changes" if we change something in the child PG... So it's still unusable for
> us with 1000 of processors within a nested Flow.
> Procedure to reproduce the bug:
> # Insert processors and PGs on the Canvas
> ** Create a "PG Parent 2.8.0" with one processor and an additional "PG Child
> 2.8.0":
> !image-2026-03-03-08-02-16-542.png!
> ** Insert three processors into "PG Child 2.8.0:
> !image-2026-03-03-08-04-19-158.png!
> # Commit "PG Child 2.8.0" to NiFi Registry
> # Commit "PG Parent 2.8.0" to NiFi Registry
> # Move processor "GenerateFlowFile Child1" on the canvas in "PG Child 2.8.0"
> and commit it to NiFi Registry
> # {color:#de350b}On the "PG Parent 2.8.0", check "Show Local Changes", this
> shows the actual bug. We do see here the new Version of the "PG Child 2.8.0",
> which is absolutely fine - however, there is as well every single processor
> from the "PG Child 2.8.0" as well. Not ok, the parent should never track
> anything from child, except the version number.{color}
