How to check if a value exists in a list of given values?
Question
New to OutSystems

Hello,

For example I have a boolean expression and I would like to set its value is True if fruit value in Session is "orange", "apple" or "lemon" and False if fruit is none of them.


I can do it with:

Session.fruit = "orange" or

Session.fruit = "apple" or

Session.fruit = "lemon" 


In case of I have 20 fruit names and I don't want to give 20 lines for it, are there any way to write it shorter? I expect something like :

Session.fruit in ("orange", "apple","lemon")

but I'm not familiar with Outsystems formular syntax.


Thank you!

Hi,

You can use ListFilter action for this to filter the particular record.



Thanks,

Sachin
