Validation in load and with and returning a boolean value

Hi,

From your question, I could understand that you're assigning the result to a variable in load() again, This will not work as load variables will be executed only once. If that's not the case, please share your code here(by using insert->code) for better understanding.

Alternatively, if your Appian version supports a!localVariables(), then it'll be a lot easier to implement.

Hi Selvakumar,

I am assigning the local variable with the result in the with and using the result in the with to pass to a child interface. 

I have a form layout in the with and I am declaring everything before the form layout. I hope the below code snippet helps to guide me. thank you.

load(
local!oldVal: employeeData_cdt.empName,

)
with(
local!isReadOnly:
if(
and(
isnull(symetricdifference(oldval,newVal)
)
)
)
a!formlayout(

rule!EMP_Details(
/*this is the child interface where we can edit the empl details and if the details are 
modified I need to update the local!ReadOnly to true or false.
)

rule!EMP_Validatedetials(
local!isReadOnly,
)
)
)

Appian is a functional language. This means that you need to nest your function call.

E.g. for load(): The first "lines" are used to define local variables created in the scope of that load() call.
