Scriptrunner Behavior to find 'None' value

[Daniel Steffano]

Hey there,

I'm working on a script that detects the field values and reacts accordingly, but I'm running into an issue where I can't accurately determine if a multi-list selection is equal to the default option, "None". The same is true even after selecting a different item, then clicking back to "None". I am able to get my code to react to the values selected otherwise.

The code is executing under the myVariable field. Any help is greatly appreciated - code below.

---

def myVariable = getFieldById("customfield_15201")

String myVariableValue = (String) myVariable.getValue()

// I've tried all of the following and none of these work.

if (myVariable.contains('None')) { ... }

if (myVariable.contains(null)) { ... }

if (myVariable.equals('')) { ... }

if (myVariable.equal('None')) { ... }

if (myVariable.equals(null)) { ... }

if (myVariable.isEmpty()) { ... }

if (myVariable.isBlank()) { ... }

Your error is with 

String myVariableValue = ( String ) TeleportField .getValue()

In my experience, it's never a good idea to perform this sort of type conversion in groovy.

A multi-select field should typically return an array. If you convert that to strings, it becomes complex to process it.

Let groovy do the work for you.

def myField = getFieldById("customfield_15201")
def myFieldValue = myField.value
if(!myFieldValue){
   //the field is not populated, that could be because it returns one of the followin
   if(myFieldValue == null){
     log.info "field is null"
   }
   if(myFieldValue instanceof String){
      log.info "field is an empty string"
   }
   if(myfieldValue instanceof List){
      log.info "field is an empty array" //this is the only one that should output on a multi-select field
   }

} else {
   if(myfieldValue instanceof List){
      //bonus, if you have values in your multi-select
       myFieldValue.each{selectedOption->
          log.info "label of the selected option is: $selectedOption"
       }
       //or if you want the optionIds
       myfield.formValue.each{optionId->
          log.info "id of the selected option is: $optionId"
       }
   }
}
