我正在将我的 grails 2 应用程序升级到 grails 4。我已经能够纠正所有编译时错误，现在应用程序运行。它在点击控制器操作时会引发此错误。
No enum constant com.company.compositeEvent.ResultsStatus.2
在控制器的这一行中
if (idList){
result = RaceGroup.createCriteria().list([sort: 'startDateTime', order: 'asc', offset: offset, max: max]){
inList('id', idList)
join 'address'
}
}
RaceGroup 有 resultsstatus 属性
ResultsStatus resultsStatus
ResultsStatus 是一个枚举，定义为
enum ResultsStatus {
NO_RESULTS(1),
RACE_RESULTS(2),
EXTERNAL_RESULTS(3)
int id
private ResultsStatus(int id){
this.id = id
}
}
它在 grails 2 中运行良好。我怀疑 grails 4 中发生了一些变化，也许定义枚举的方式是错误的。我感谢任何指南。
