Number of conflicts while synchronizing: 4 SyncResolver.INSERT_ROW_CONFLICT

Question

Hi All,
I have a problem saving edits and new rows to a data table.
I get the following error Number of conflicts while synchronizing: 4 SyncResolver.INSERT_ROW_CONFLICT
This is described as :
Indicates that a conflict occurred while the RowSet object was attempting to insert a row into the data source. This means that a row with the same primary key as the row to be inserted has been inserted into the data source since the last synchronization.
I can see however that the code is generating new primary keys as it should so I am baffled.
The code for the addItem button and save changes is shown below.
Any insight welcome
Thanks
Jim
public String addItemButton_action() {
try {
RowKey rk = productsDataProvider.appendRow();
productsDataProvider.setCursorRow(rk);
productsDataProvider.setValue("PRODUCTS.PRODUCTINFOID",new Integer(0));
productsDataProvider.setValue("PRODUCTS.PRODUCTID",new String("A"));
productsDataProvider.setValue("PRODUCTS.INFO",new String("B"));
productsDataProvider.setValue("PRODUCTS.RPRICE",new Integer(3));
productsDataProvider.setValue("PRODUCTS.WPRICE",new Integer(5));
productsDataProvider.setValue("PRODUCTS.STYLE",new String("C"));
productsDataProvider.setValue("PRODUCTS.TYPE",new String("D"));
productsDataProvider.setValue("PRODUCTS.STOCK",new Integer(8));
productsDataProvider.setValue("PRODUCTS.DELAY",new Integer(9));
productsDataProvider.setValue("PRODUCTS.COLOUR",new String("E"));
productsDataProvider.setValue("PRODUCTS.MATERIAL",new String("F"));
productsDataProvider.setValue("PRODUCTS.SIZE",new String("G"));
productsDataProvider.setValue("PRODUCTS.ROOM",new String("H"));
productsDataProvider.setValue("PRODUCTS.SHOW",new String("bool"));
productsDataProvider.setValue("PRODUCTS.SUPPLIERID",supplierDD.getSelected());
} catch (Exception ex) {
log("Error Description", ex);
return null;
// Get the next key using result of queery on MaxProducts data provider
public String saveChanges_action() {
try {
CachedRowSetDataProvider maxProducts = getSessionBean1().getMaxProductsDataProvider();
maxProducts.refresh();
maxProducts.cursorFirst();
int newProductInfoID = ((Long)maxProducts.getValue("MAXPRODUCTSINFOID")).intValue();
//Navigate through rows with data provider
if (productsDataProvider.getRowCount()>0){
productsDataProvider.cursorFirst();
do {
if(productsDataProvider.getValue("PRODUCTS.PRODUCTINFOID").equals(new Integer(0))){
log("In the start of the if..."+newProductInfoID);
error("In the start of the if..."+newProductInfoID);
productsDataProvider.setValue("PRODUCTS.PRODUCTINFOID", new Integer(newProductInfoID));
newProductInfoID++;
//log("In the if...");
//error("In the if...");
}while (productsDataProvider.cursorNext());
productsDataProvider.commitChanges();
log("After commitChanges(...");
error("After commitChanges...");
} catch (Exception ex) {
log("Couldnae save the changes", ex);
error("Couldnae save the changes"+ ex.getMessage());
return null;
}

have you tried using an auto increment field for your primary key in your database table - you can then use the cached rowset's setInsertableColumns() method to include all but the primary key field, and your db autogenerates the next value(s) on insert - it seems to working swimingly on MySQL and saves a lot of messy code
(you can can still do all your field assignments with the dataprovider)
