Incorrect arguments to mysql_stmt_execute

Question

Hi there,
i'm spending 2 days by trying to solve an apparently stupid problem:
I'm using DataProvider and RowSet in a simple jsf page. The table I want to update is composed by 3 FK and 1PK(auto-increment). DBMS=MySQL.
I can insert without problems by using setInsertableColumns.
The problem arises when I try to update. This is the code:
!!!! CODE snippet !!!!
CachedRowSetX crs = (CachedRowSetX)listino_dettaglioDataProvider.getCachedRowSet();
crs.setUpdatableColumns( new boolean[] { true, true, true, true,false } ) ;
mDataProvider.setValue("t.PRO_ID",id,proid); // FK field
...toher FKs...
mDataProvider.setValue("t.PRICE",id,price); // simple field
...NO PK setting...just row update...
mDataProvider.commitChanges();
!!!THIS the ERROR:!!!
Number of conflicts while synchronizing: 1 SyncResolver.UPDATE_ROW_CONFLICT row 1 Incorrect arguments to mysql_stmt_execute
!!!THIS IS PRINTSTATEMENTS OUTPUT!!!!
INSERT INTO dbmultisite2.t (PRO_ID, PRICE, FAS_ID, LIS_ID) VALUES (?, ?, ?, ?)
SELECT PRO_ID, PRICE, FAS_ID, LIS_ID, LISDET_ID FROM dbmultisite2.t WHERE PRO_ID = ? AND PRICE = ? AND FAS_ID = ? AND LIS_ID = ? AND LISDET_ID = ?
Paramm[1]=(java.lang.Integer,1) Paramm[2]=(java.math.BigDecimal,0.10) Paramm[3]=(java.lang.Integer,12155) Paramm[4]=(java.lang.Integer,17) Paramm[5]=(java.lang.Integer,21)
Writer: executing pre-update SELECT
!!!! END !!!!
so my questions are:
- why INSERT????
- what argument is incorrect?? I ask this because when you go wrong this a column the jdbc says "ColsXYZ error...." but, in this case, the stmt is wrong but no more info I can get.
- I used the same approce with other tables with/out FKs,PK and I have no problem...
can some1 give me an explanation?
tnx
