Visibility Condition on Multiple Links From Index Unit

Hi everyone,

I'm using a List Component in order to show some objects stored in the database.

Each object has a "status" attribute, which can assume 3 different values.

From the list component I have 3 different outgoing links.

Basing on the value of "status" I would like to show the appropriate link for each object.

I've looked at the Visibility Conditions, but as far as I have understood, when using List Components, I can apply a conditional expression to ALL the links.

What I have to do is to specify a different conditional expression for each link.  

For example, considering an object "object1" from the list, I have an outgoing link "link1" only if "status == value1" for "john".

Hi Davide,

in this article there's a section called "Flow Visibility Condition" that explains how to hide/show flows according to a value.

In your specific example you can work like this:

  • create a page variable (stateVar) based on the state attribute of the list
  • create an activaction expression into the same page that checks a condition like this 
    return (stateVar == 'value1')
    where 'value1' is the value you want to use to hide flows
  • pick the list component from the page and open the layout view
  • pick the list component from the layout view, it should show you the layout outline on the top left of the window
  • unpack the list component and pick the flow you want to manage
  • from the properties view set a visibility condition for the flow using the 'NOT' operator to revert the boolean result

This should do the job.

Sorry, there is a typo. At the end of the question "john" = "object1".
