---------------------------------
Summary: Improve Parameter Usage
Key: NIFI-6580
URL: https://issues.apache.org/jira/browse/NIFI-6580
Project: Apache NiFi
Issue Type: Improvement
Components: Core UI
Reporter: Scott Aslan
Currently when viewing a referenced parameter the usage is displayed in a set
of expandable/collapsable 'twisties' that are grouped by their PG. These
'twisties' are expanded by default but the user can choose to collapse a group.
The issue is that if the user has collapsed any of the groups of 'twisties'
while viewing the usage of a parameter and then the user applies any changes to
that parameter value or description then the entire usage is re-rendered again
showing all referenced components grouped by PG with all groups again expanded.
This issue is mostly a UX issue but it is also a performance concern in that we
probably don't need to recreate the groups of 'twisties' every time we poll an
update request. The list of referenced components won't change but the status
and bulletins might. So rather than re-rendering the entire set of 'twisties'
we could just update the status and bulletin info.
