List Count

Type: list-count  ·  Package: Collections Activities v1.0.3  ·  Output: int

Gets how many elements a list has.

How it works

Counts the elements of list (including null ones) and returns the number. It does not modify the list.

Required parameters

Parameter	Type	Default	Description
list	List	—	The list.

Optional parameters

None.

Output

Returns an int with the number of elements; 0 if the list is empty.

Common errors

Message	Cause and fix
'list' must be a List, got ….	list is not a list (the message shows the type received, or null if the variable is empty).

Example

List Count   list = pending   → output: total
If   condition = total > 0
 └─ then:
      Log   message = "There are " + total + " pending"
