Subject Re: process group name reverts back to initial value if I do a nifi registry "Change version"
Date Mon, 14 Jan 2019 07:23:41 GMT
Thanks Chad for confirming it.

@Bryan Bende: how shall we continue here? I understand that it isn't a high prio issue, however
it would be great to get it fixed or at least know that it will be fixed in one of the future
releases...

Cheers Josef

    Bryan/Josef,
    
    Just wanted to let you know that I just tested this with NiFi 1.8.0 and NiFi Registry
0.3.0 and I experience the same behavior as Josef.

my first test below I've changed a variable on a processor inside the PG and the second time
(a few seconds ago) I've added a connection to my "Execute Script" processor. All the time
my second PG with the new name changed back to the initial name... Even if I just click "Change
version" and select another one than the current, my second PG changes the name back to the
initial value.
