IBM Watson Conversation: How to capture and retrieve a list of values in a variable

I have a dialog where users can enter one or more country names. How do I retrieve the values from the entity defined to store the responses.

Example : Entity : Country

Question : Where did you travel to?
Answer : Africa, Thailand and China.

How can I capture these 3 values in a list entity?

Its Quite Simple. Use 

"countries": "@sys-location.values"

It will list all @sys-location values in array form.

Henrik is right, just to add to that, What he said will return them in an array, if you do 

"countries": "<? entities['sys-location'] .toString() ?>"

you will get a comma separated list of the locations returned.

You can use the system entity for locations, @sys-location. You need to turn that capability on for your workspace. See the wizard for entity creations.

In your dialog node where you want to capture the input in a list, you can assign those countries to a context variable. Switch to the JSON editor to edit variables. Then do something like:

"context": {
    "countries": "<? entities['sys-location'] ?>"
  },

See my collection of examples for context processing for something similar.

@sys-location entity in System Entities extracts location from the conversation. (Note: Ensure that you have switched on that entity as shown below)

You can now see that location has been extracted from conversation
