java.lang.IllegalArgumentException: wrong number of arguments
报错的是参数个数不对，确认一下具体怎么操作会报错

dh_n

我可以导入，同样的代码换一台电脑就不行了，不是参数个数的问题，我检查过和mapping里面一样的

dh_n

我昨天可以的，今天也导入报错这个错误了

这几个错误就是参数的问题

dh_n

可以远程吗

jishuang

确认具体怎么操作报错的？是否自己写了导入前后事件，事件中的代码有问题
平台默认带的案例/UI2/system/components/justep/excel/demo/excel.w是否有问题

dh_n

其他的可以导入。这个导入的数据源设置了主从表，导入从表报错，我试过mapping只设置一个字段，然后导入也是报错的

jishuang

主从设置去掉导入就不报错了？

dh_n

有导入的模块，模型编译后可以导入，但是过一会就又报错参数问题了
