I am getting values from database and I am displaying it and the filter is working fine. Now the Requirement is i need to add NULL Name in dropdown and display those names that are NULL.
I am using append(local!dropdown,"NULL Name").
local!dropdown-- It has a rule that is used to display Dropdown value.
My doubt is I need to Display NULL Name dynamically, i.e: if any value is Null then only i can see this option in dropdown.
I am using below code but its wrong(as am comparing directly with NULL and value can be like: {Name1,Name2,Name3,Null}) can someone help me on this
local!dropdownList: if(local!dropdown="NULL", append("NULL Name"),local!dropdown)

You need to add logic based on your choice Values.local!choiceValue: Get all options from the source { Name1, Name 2, Name3, Null}
local!noNullChoiceValue: use reject function to discard null. Expected out put as { name1, Name2, Name3 }
local!option:
if count ( local!choiceValue ) = count ( local!noNullChoiceValue ) then pass anyone ( local!ChoiceValue or local!noNullChoiceValue)
Else append ( local!noNullChoiceValue, NULL ),
a!dropdown(.....
....
.....

Has anyone tried this?
I still get the error message "A dropdown component [...] has an invalid value for "choiceValues". Choice values cannot be null.". Of course local!option contains null. Or what am I missing?
I think you cannot have null as value in the dropdown instead it should be text "Null"
append ( local!noNullChoiceValue, "NULL" )
I think this is super confusing. And no, you cannot put a NULL value into the list of choice values.
But maybe if you try to explain what you want to achieve ...
