How to Retrieve Data

Question

Hi Everyone, 
 I need to get "choiceLabels" and "choiceValues" list from the dictionary as shown in screenshot. Can anyone please help me how to get it?

Stefan Helzle · Answer

We need a bit more context. 
 In general, as per the Appian documentation, we use the dot-notation to fetch values from dictionaries.

Harsha Sharma · Answer

Whichever rule or variable this data is coming from, you can get the fields using property(), index() or dot-notation. index(local!data,"choiceValues",{})
property(local!data,"choiceValues",{})
local!data.choiceValues

Harsha Sharma · Answer

You can try like this 
 {
 index(local!data,"choiceLabels",{}),
 index(local!data,"choiceValues",{})
}

If i understood correctly, you need to retrieve choiceValue and choiceLabel from dictionary. Use index() for null safe expression local!choiceLabels: index(yourDictionary, "choiceLabels", {}), local!choiceValues: index(yourDictionary, "choiceValues", {}), Check below interface expression for your reference. a!localVariables(
 /* Example dictionary similar to yours */
 local!myDictionary: a!map(
 choiceValues: {"001", "002", "003", "004", "005"},
 choiceLabels: {"Option 1", "Option 2", "Option 3", "Option 4", "Option 5"},
 data: {/* your data here */}
 ),

 /* Extract both lists */
 local!extractedLabels: index(local!myDictionary, "choiceLabels", {}),
 local!extractedValues: index(local!myDictionary, "choiceValues", {}),

 /* Variable to store selected value */
 local!selectedValue: null,

 /* Display in a form */
 a!formLayout(
 titleBar: "Dictionary Example",
 contents: {
 /* Use in dropdown */
 a!dropdownField(
 label: "Select an Option",
 placeholder: "Choose...",
 choiceLabels: local!extractedLabels,
 choiceValues: local!extractedValues,
 value: local!selectedValue,
 saveInto: local!selectedValue
 ),

 }
 )
)
