Есть пример, если вы имеете в виду ScriptRunner Simple Validator:
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.customfields.manager.OptionsManager
cfId = 121500L // paste you field id here
cfValue = getCustomFieldValue(issue, cfId)
cfOptions = getCfOptions(issue, cfId)
return cfValue?.size() == cfOptions?.size()
// return current cf value
def getCustomFieldValue(issue, Long cfId) {
issue.getCustomFieldValue(ComponentAccessor.getCustomFieldManager().getCustomFieldObject(cfId))
}
// returns all options for select custom field
def getCfOptions(issue, Long cfId) {
def cfObj = ComponentAccessor.customFieldManager.getCustomFieldObject(cfId)
def fieldConfig = cfObj.getRelevantConfig(issue)
ComponentAccessor.getComponent(OptionsManager).getOptions(fieldConfig)
}
