The array is:

0: This is the value at index zero
1: This is the value at index one

The text input gives this:

( "<BehaviourInputField: 0x174a56c50> = { \n\tControlled By = self \n\tValue Key = (null) \n\tValue: This is the value at index zero \n}", "<BehaviourInputField: 0x17444add0> = { \n\tControlled By = self \n\tValue Key = (null) \n\tValue: This is the value at index one \n}" )

Dictionaries do the same thing:

{ "my first key" = "<BehaviourInputField: 0x170e56410> = { \n\tControlled By = self \n\tValue Key = (null) \n\tValue: my first value \n}"; "my second key" = "<BehaviourInputField: 0x170c50440> = { \n\tControlled By = self \n\tValue Key = (null) \n\tValue: my second value \n}"; }
