No columns in table error when committing via CachedRowSetDataProvider

Question

Okay, another issue that's had me scratching what's left of my hair over the past couple of days.
I've got a CachedRowSetDataProvider tied to a CachedRowSetXImpl. This rowset pulls all data back from a table (command = select all FIRST_NAME, LAST_NAME from t_person). I want to insert/append a new row into that table. I'm doing something like the following:
RowKey rk = t_rolesDataProvider.appendRow();
t_rolesDataProvider.setCursorRow(rk);
t_rolesDataProvider.setValue("FIRST_NAME", fName);
t_rolesDataProvider.setValue("LAST_NAME", lName);
t_rolesDataProvider.commitChanges();
When it gets to the .commitChanges() line, I get the following error:
java.sql.SQLException: No columns in table: t_person
I've seen this reported a couple other times but haven't been able to find anything that helps me with my issue (even though what I'm doing seems much simpler than the other reports I've seen).
I've also reviewed several of the blogs regarding how you're supposed to be able to do this (insertableColumns and all that) but if there are any other resources, I'd appreciate them as well.
Here's the kicker, it works fine when I'm pointing to a MySQL database but when I switch over to an Oracle database, I start getting these errors.
It only seems to be an issue when I go to insert, update or delete data. I can display data from these same tables just fine with either driver/database.
Please help!
Thanks,
TJ

I am also having this error inserting into mySQL table. I am updating a view.. But the view is of the base table, so it should be updatable. When I debug this, I see that the "FieldKeys" is fully populated, and the I see nothing irregular inside the DataProvider.
getPDataProvider().cursorLast();  \\ added to try and populate columns
if ( getPDataProvider().canAppendRow() ) {
    try
        getSessionBean1().getPRowSet().execute(); \\ added to try and populate columns
        RowKey rowKey = getPDataProvider().appendRow();
        getPDataProvider().setCursorRow(rowKey);
        getPDataProvider().setValue("partys.PartyId"        ,rowKey, (new Integer(0)));              
        getPDataProvider().setValue("partys.GameId"         ,rowKey, (new Integer(this.getSessionBean1().getSelectedGameId() )));                          
        getPDataProvider().setValue("partys.HostId"         ,rowKey, (new Integer(this.getSessionBean1().getCurrentHostId()  )));                          
        getPDataProvider().setValue("partys.PartyName"      ,rowKey, "Enter Party Name Here" );                          
        getPDataProvider().setValue("partys.StatusId"       ,rowKey, (new Integer(0)));                                                     
        getPDataProvider().setValue("partys.PartPassCode"   ,"Enter Password" );                          
        getPDataProvider().setValue("partys.PersonalMessage",rowKey, "Were having a Party" );  
        getPDataProvider().commitChanges();
    }catch (Exception e) {error("Cannot create new reocord: " + e); return("stay"); }Has anyone found this problem ???
