So, it seems to be mysql_jdbc_river's problem? Here is my sql query: "SELECT concat(fid,cmid) as _id .... FROM forum JOIN comment ..." I set the concatenation of two integer fields to be the primary key and causes the problem I described above.. Now I am dividing two tables into separate Types within an Index and using their own integer id as the primary key.
