My requirement is to display current month as default option in dropdown and user can change month value from dropdown if they want to change and for each month there should be integer value saved in Rule Input "selectedMonth", so I have applied dropdownFieldByIndex() function for this. If user select blank then it will revert it to current month but I am getting below issue:
SAIL Code:
local!currMonth: datetext(today(),"M"), local!monthName: {"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"},
a!dropdownFieldByIndex( label: "", labelPosition: "ABOVE", placeholder: "--Select Month--", choiceLabels:union(local!monthName,local!monthName), /*choiceValues: tointeger(union(local!monthValue,local!monthValue)),*/ value: if(rule!APN_isNotBlank(ri!selectedMonth),ri!selectedMonth,local!currMonth), saveInto:ri!selectedMonth, searchDisplay: "ON" )
Can anyone help with this what is the issue?

I've copied your code into the Appian environment I am working in and it seems to work for me .The only thing I had to change was that I don't have access to rule!APN_isNotBlank:
a!localVariables( local!currMonth: datetext(today(),"M"), local!monthName: {"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"}, a!dropdownFieldByIndex( label: "", labelPosition: "ABOVE", placeholder: "--Select Month--", choiceLabels:union(local!monthName,local!monthName), /*choiceValues: tointeger(union(local!monthValue,local!monthValue)),*/ value: if(rule!GBL_isNotBlank(ri!selectedMonth),ri!selectedMonth,local!currMonth), saveInto:ri!selectedMonth, searchDisplay: "ON" ) )
...otherwise it's identical to what you've provided., I do not see an error.
There is a possibility that you're passing 0 in the value of ri!selectedMonth from, say, a process that has this User Interface inside a User Input Task...in which case you need to default the value to null and not 0
Stewart Burchell: Thanks for your response. I am passing the ri!selectedMonth in UserInputTask through Process model then I am getting error. What steps should I apply to fix the issue.
Where you are mapping the pv!selectedMonth into your Interface (inside the data mapping of the User Input Task) default the value to null.
isn't the default value of a pv of type integer = 0?
Yes. So you have to override if you want to pass this to the User Interface. Or, as an alternative, catch it in the rule input in the Interface and, if set to 0, override it to null. Or set it to the current month value if it's initialized to 0. Or any other of a dozen ways to skin a proverbial feline!
