--------------------------------
Summary: During process group creation, if no name is provided,
improve error pop-up and do not close creation window
Key: NIFI-6160
URL: https://issues.apache.org/jira/browse/NIFI-6160
Project: Apache NiFi
Issue Type: Improvement
Components: Core UI
Reporter: Andrew Lim
When creating a Process group and provided no name, a pop-up appears with the
title "Create Process Group" with the message "The group name is required."
Selecting OK returns the user to the canvas.
It should be more like RPG creation. During RPG creation, if no name is
provided a pop-up with the title "Configuration Error" is shown with the
message "The URI of the process group must be specified." Selecting OK returns
the user to the Add Remote Process Group window. This is a good UX.
So applying this to a process group. If no name is supplied:
* open a pop-up with the title "Configuration Error"
* the message should say "The name of the process group must be specified."
* Selecting OK returns the user to the "Add Process Group" window
