All selected values must be present in the choiceValues array

Question

Hi. I have a dropdown list. It fails when I select one of the values. Here is the code: 
 a!localVariables(
 local!formAnswer: {
 function: "",
 subFunction: ""
 },
 local!dynameiceValue: {
 functionList: rule!JRA_QRY_getBusinessOwnerFunctionList_AbbVie(),
 subFunction: rule!JRA_QRY_getbusinessOwnerSubFunctionList_AbbVie(
 businessOwnerFunction: local!formAnswer["function"]
 ),
 },
 {
 a!dropdownField(
 label: "function",
 value: local!formAnswer["function"],
 placeholder: "select",
 choiceLabels: local!dynameiceValue["functionList"],
 choiceValues: local!dynameiceValue["functionList"],
 saveInto: a!save(local!formAnswer["function"], tostring(save!value))
 )
 }
) 
 I get the options by query rule and put it into a variable. It looks like good. But it will throw the error when I select the value. 
 
 This is the error message: 
 Interface Definition: Expression evaluation error at function a!dropdownField [line 23]: A dropdown component [label="function"] has an invalid value for "value". All selected values must be present in the choiceValues array, but value was Affiliate and choiceValues was Affiliate; Allergan Aesthetics (AA) Commercial; Commercial; Corporate; Research & Development. 
 
 The value "Affiliate" is in the choiceValues. So I do not understand why it fails

The problem is that you create your local data using "{}". Appian looses the data type when accessing the fields. In your situation I recommend to create the dictionaries using the a!map() function and/or apply tostring() on the value and touniformstring() on choicevalues.
