We receive a structure of input which is nested and complex object json maximum upto six level down. That input we cast it to a similar CDT structure inorder to display in a dynamic interface.

What kind of CDT have you created? You are going 6 levels down in a CDT? 😲

1. First thing I would do is figure out why the value loads as empty into the interface.

As a side note your CDT design is very complex where you have 6 levels of nesting (waterfall effect) this is generally an anti-pattern

1. ri!final_PRN_CDT

2. PrnSegment

3. Providers[1]

4. ServiceLocation

5. Addresses[ri!index]

6. ExpandClicked

I would suggest to revisit these links to adjust your design

https://community.appian.com/w/the-appian-playbook/1199/working-with-advanced-cdt-structures

2. Another simple solution is to simply do something of the sort

a!save(
    ri!final_PRN_CDT.PrnSegment.Providers[1].ServiceLocation.Addresses[ri!index].ExpandClicked,
    if(
        a!isNullOrEmpty(
            ri!final_PRN_CDT.PrnSegment.Providers[1].ServiceLocation.Addresses[ri!index].ExpandClicked
        ),
        true(),
        false()
    )
)

This is very confusing ... In a case where I have a hard time to understand what is going on, I try to simplify my code and get rid of external dependencies.

I have one observation. Below is a CDT boolean property when i debugged i see it has empty value when form loads and on first card layout clcik its set to false then on second clcik showdetails is changing value.

index(
            index(
              index(
                index(
                  index(
                    ri!final_PRN_CDT.PrnSegment.Providers,
                    1,
                    {}
                  ),
                  "ServiceLocation",
                  {}
                ),
                "Addresses",
                {}
              ),
              ri!index,
              {}
            ),
            "ExpandClicked",
            false()
          )
