How to use a Radio Button to validate a transition

Question

I'm trying to setup a 'Simple Scripted Validator' using ScriptRunner. That allows the transition, if the Radio button in question has 'No' selected.

"import com.atlassian.jira.component.ComponentAccessor
// Get the custom field managerdef CustomFieldManager = ComponentAccessor.getCustomFieldManager()
// Get the custom field by namedef approvalField = customFieldManager.getCustomFieldObjectsByName("Verification?")
// Get the value of the custom field for the current issuedef approvalValue = issue.getCustomFieldValue(approvalField as String)
// Check if the custom field value is not "Yes"return approvalValue != "Yes"
    return true"The Script Editor likes the code, but the transition is blocked, whether 'Yes' or 'No' is selected!? Can anybody show me where my code is wrong please?Thanks.

I think that getCustomFieldObjectsByName returns a collection of CustomField objects and you're looking at that collection as though it's a discreet "yes/no" value.

Try something simpler:

def approvalValue = issue.getCustomFieldValue("Verification?")
