Grails groovy boolean返回为null

我有一个函数，它在服务类中返回两个整数和一个布尔值：

def setEntityRecordBalance(EntityRecord entRec, Map params) {
        float totalBalance = 0
        int redIssues = 0, yellowIssues = 0
        boolean insured = false

        /* For each account owned by this entity, get its figure in USD and then add to running total. */
        if (entRec.accounts == []) {
            redIssues++
            setCleanFlag(entRec.redIssues, 'No accounts found.')
            return [redIssues, yellowIssues]
        }
        else {
            entRec.accounts.each {
                def account = AccountRecord.findWhere(uniqueId: it.uniqueId, accountId: it.accountId,
                                                    batchID: params.selectedBatch.id)
                if (account.amount == null)
                    totalBalance += 0
                else
                if (account.currencyType == null || account.currencyType.equalsIgnoreCase('USD'))
                    totalBalance += account.amount
                else
                    totalBalance += getUSDamount(account)

                if (account.insurance != null && (account.insurance.equalsIgnoreCase('Y') || account.insurance.equalsIgnoreCase('YES')))
                    insured = true  
            }
        }
        entRec.balance = totalBalance
        return [redIssues, yellowIssues, insured]
    }

现在，在同一个服务类中，我在一个函数中有另一个语句，它调用这个函数，如下所示：

def (redFlags, yellowFlags, insured) = setEntityRecordBalance(newEntityRecord, params)
    println "<><><> Value of insured: " + insured + " " + redFlags + " " + yellowFlags
def (redFlgs, yellowFlgs, isReportable) = setEntityRecordBalanceFlags (newEntityRecord, insured)

def（红旗、黄旗、被保险）=setEntityRecordBalance（newEntityRecord，参数）
println“投保价值：“+投保+”+红旗+“+黄旗”
def（红色、黄色、可报告）=setEntityRecordBalanceFlags（新EntityRecord，投保）

我得到两个整数，但是布尔值返回为空，为什么

这是我得到的错误：

return [redIssues, yellowIssues]

您只返回2个元素，没有第三个布尔值，谢谢。哇，现在感觉不像是智人了。一直盯着代码看太久了，不用担心。有时需要另一双眼睛>_
