Jsf 嵌套EL表达式失败

我有一个表达式如下

#{af:formatNamed2(repo['PARAM'],'NUMBER', someScope.CurrentWorkerIndex, 'TOTAL_NUMBER', someScope.TotalNumberOfWorkers)}"

我需要在以下条件之间切换最后一个参数的值：

someScope.TotalNumberOfWorkers < 0 ? 500 : someScope.TotalNumberOfWorkers

someScope.TotalNumberOfWorkers<0？500:someScope.TotalNumberOfWorkers

我尝试了所有这些，但都失败了：

测试一：

#{af:formatNamed2(repo['PARAM'],'NUMBER', someScope.CurrentWorkerIndex, 'TOTAL_NUMBER', [someScope.TotalNumberOfWorkers < 0 ? 500 : someScope.TotalNumberOfWorkers])}"

{af:formatNamed2（repo['PARAM']，'NUMBER'，someScope.CurrentWorkerIndex，'TOTAL_NUMBER'，[someScope.TotalNumberOfWorkers<0？500:someScope.TotalNumberOfWorkers]）”

测试二：

#{af:formatNamed2(repo['PARAM'],'NUMBER', someScope.CurrentWorkerIndex, 'TOTAL_NUMBER', (someScope.TotalNumberOfWorkers < 0 ? 500 : someScope.TotalNumberOfWorkers))}"

{af:formatNamed2（repo['PARAM']，'NUMBER'，someScope.CurrentWorkerIndex，'TOTAL_NUMBER'，（someScope.TotalNumberOfWorkers<0？500:someScope.TotalNumberOfWorkers））“

请建议

我为我的愚蠢道歉，我想我明白了

问题是，我为我的愚蠢道歉，我想我明白了

问题出在

someScope.TotalNumberOfWorkers < 0 ? 500 : someScope.TotalNumberOfWorkers

someScope.TotalNumberOfWorkers lt 0 ? 500 : someScope.TotalNumberOfWorkers
