PCF/Dynamic UI
Array-Backed List Views - ANS-- best for short lists
- full set of data is loaded when the LV is rendered
- full set of data is reloaded when sorting/filtering the LC or when navigating between
pages.
- Paging. sorting, and filtering are supported while editing the data.

Describe a List View configuration that causes poor performance - ANS-- Retrieving an
item outside the view entity backing the LV
- Retrieving an entire entity instead of its DisplayName

List Post On change configurations from most expensive to least** - ANS-1) Having no
value in the target property
2) having a widget ID specified in the target property
3) onChange function is specified
4) Having DATA_ONLY specified in the target property.

Name some expensive expressions - ANS-- Array expansion (array*.stuff)
- collection methods: allMatch(), hasMatch(), countWhere(), first(), firstWhere(), last(),
lastWhere()
- dot notation object.array.object.blah.blah

Problem: a PCF has performance issues due to the entire page being refreshed, or due
to the use of an expensive method call in an onChange Property - ANS-Solution:
Consider what really needs to be refreshed on the page. Anything is better performing
than leaving the target property empty.

Problem: a PCF Performance problems due to same expensive method or expression
being caled over and over again - ANS-Solution: Evaluate the expression in a PCF
Level variable so it is only evaluated once.

Problem: Examining role privileges directly, testing the current user to determine if they
have a specific role. - ANS-Solution: Perm.System.edituserDetails_ext

Problem: page usage not considered when implementing dynamic behavior -
ANS-Solution: use dynamic widget (input group or input set) to test condition once for
entire set of widgets. You want to test this once, not one time for each field!
