dropdown doubt

First check what is the value you mentioned in Value field here and then check if that value exist in choice value array or not

On line 352 try changing from ri!medicalInformation.modeOfRequest to ri!medicalInformation.modeOfRequestId or another field which has the request ID. If you don't have that, then you should just do index(local!selectModeOfRequest, "modeOfRequestName",{}) in the choiceValues field

Hi,

Looks like issue with typecasting as local variable could be of dictionary type.If your choice values are list of text string and you are trying to store them in integer rule input value then you could get such error.

Try to compare your local values with below and see if it helps:

a!localVariables(
  local!selectedModeOfRequest: {
    {"name": "In Person", "id": "1"},
    {"name": "Call", "id": "2"},
    {"name": "Mail", "id": "3"}
  },
  {
    a!dropdownField(
      label: "Dropdown",
      labelPosition: "ABOVE",
      placeholder: "--- Select a Value ---",
      choiceLabels: local!selectedModeOfRequest.name,
      choiceValues: tointeger(touniformstring(local!selectedModeOfRequest.id)), 
      value: ri!selected.id, /*id is Number*/
      saveInto: ri!selected.id,
      searchDisplay: "AUTO",
      validations: {}
    )
  }
)

Thank you, everyone. I tired these scenarios, 

danny.verb your scenario works , Thank you.

And a small doubt not regarding this issue but a general one, In Interface components like section layout or billboard layout we have a parameter called "accessibilityText" .  

I know we cannot see when we add it like this(accessibilityText: "for readers only") but what 

"Used only for accessibility; produces no visible change"  means exactly. Could please give an example or a simple explanation, please
