Issue with datetext function with different locale settings

yea, nice to play with this

I wrote this expression to analyse it from 1930 for the next 100 years

The years where it outputs wrong repeats in an order of 4,3,3,3,3,4,3,3,3,3,4,...

and similarly where it comes correctly are: 3,2,2,3,2,3,2,2,3,2,3,...

I wonder something gets messy due to leap years or so.....

Hope the screenshot highlight helps and hope Appian reads this post and can use it 🙂

a!localVariables(
  local!startYear: 1930,
  a!forEach(
    items: enumerate(2030 - local!startYear),
    expression: a!localVariables(
      local!date: "12/29/" & local!startYear + fv!index - 1,
      local!datetext: datetext(todate(local!date), "dd MMM YYYY"),
      local!text: text(todate(local!date), "dd MMM YYYY"),
      local!equal: local!datetext = local!text,
      "Input Date: " & local!date & "  |  Date Text Function: " & local!datetext & "  |  Text Function: " & local!text & "  |  Match: " & local!equal
    )
  )
)

Hi there,

Try using text() function instead of dateText()

I think datetext has a kind of bug. I played a bit with it.

a!localVariables(
  local!date: todate("12/29/2007"),
  a!formLayout(
    contents: {
      a!textfield(
        value: datetext(local!date, "dd MMM YYYY"),
        readOnly: true
      )
    }
  )
) -> until that date correct result

a!localVariables(
  local!date: todate("12/29/2008"),
  a!formLayout(
    contents: {
      a!textfield(
        value: datetext(local!date, "dd MMM YYYY"),
        readOnly: true
      )
    }
  )
) -> 29 Dec 2009 until 2015-> 29 Dec 2016
a!localVariables(
  local!date: todate("12/29/2016"),
  a!formLayout(
    contents: {
      a!textfield(
        value: datetext(local!date, "dd MMM YYYY"),
        readOnly: true
      )
    }
  )
) -> 29 Dec 2016  until 2018-> 29 Dec 2018

a!localVariables(
  local!date: todate("12/29/2019"),
  a!formLayout(
    contents: {
      a!textfield(
        value: datetext(local!date, "dd MMM YYYY"),
        readOnly: true
      )
    }
  )
) -> 29 Dec 2020  and 2021 -> 29 Dec 2022
2022 is correct again. Not sure what the issue could be

weird !

here's an alternative if you need it

use: text(ri!date, "dd MMM YYYY")

I did see the same thing happening. Switched local couple of times, used date selector, userdatevalue() and date() functions as input. After that issue didn't occur anymore. Strange
