Hi.
We recognized that with changing the parameter suggestion list from the HTML
list to a div container the suggestion does not work for context parameter
names with dots anymore.
It looks like as if the regex, which is responsible for the list filtering,
does not escape "." properly into "\." .
I think it relates to bug report NIFI-15373.
*How to reproduce:*
Below are screenshots of a comparison between Nifi 2.7.2 and Nifi 2.2.0 (tested
on the version starting from here).
Just create a parameter context with parameter names having dots.
On the canvas add for instance an UpdateAttribute processor and add an
attribute. The value points to a parameter of the PG assigned context.
*_Nifi 2.7.2_*
List of test scenario parameters

Typing parameters with "_" and other alphanumerical characters

The suggestion list appears properly.
Typing parameters with "." and other alphanumerical characters

With the first dot, everything seems ok. Continuing typing
!image-2025-12-19-12-04-09-956.png|width=270,height=163!
The list disappears.
_*Nifi 2.2.0*_
All the same scenario.

Typing parameters with "_" and other alphanumerical characters
!image-2025-12-19-12-05-29-410.png|width=310,height=152!
Same with dots
!image-2025-12-19-12-05-56-066.png|width=274,height=114!
The two parameter names appear in the suggestion list.
