jfinal oracle分页的问题?报错

@jfinal 波总，我这里已经启用了oracle dialect

ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);
arp.setDialect(new OracleDialect());//oracle数据库方言

但是用Db.paginate(pageNumber, pageSize, select, sqlExceptSelect);方法后报错：

com.jfinal.plugin.activerecord.ActiveRecordException: java.sql.SQLSyntaxErrorException: ORA-00918: 未明确定义列

	at com.jfinal.plugin.activerecord.DbPro.paginate(DbPro.java:490)
	at com.jfinal.plugin.activerecord.DbPro.paginate(DbPro.java:500)

查询中有max、nvl、case when等函数.

主要是有连接，报错了。

后台打印的sql类似这样的：

select *
  from (select row_.*, rownum rownum_
          from (SELECT a.*,
                       b.*
                  FROM  a
                  left join  b on a.pid = b.pid
                ) row_
         where rownum <= 10) table_alias
 where table_alias.rownum_ >= 1
