JBO framework - BUG ! very URGENT !!!!

Question

Hi JDev-Team,
there seems to be a bug in the JBO implementation of the JDev 3.1.
I have used the JboHtml Beans to generate a JSP application, but because the beans are still young and didn't face some of my problems, I make some changes to extended them.
More exactly I added some features to the RowSetBrowser bean that enables my application to have a master detail information autogenerated via JavaScript, from extra columns of the rowsetbrowser, something like the show recordnr and editurl.
After I make changes in these details (JavaScript generated) I do a post(html form) with the target set as the page with the RowSetBrowser bean and in the render() I look for data that has to be changed.
I apply these changes to the table using the
getApplicationModule().getTRansaction().executeCommand(sqlstmt).
So far everything is ok.
Now this is what's happening. Let us have this scenario :
1. open the RowSetBrowser, navigate to one rec, do a edit using the EditCurrentRecord()
this operation I can repeat n-times, no problem.
2. now I try to modify some information in my javascript details, post is ok, data is changed.
again I can repeat this step n-times, no problem again.
3. if I like now to do step 1 after 2, I got always a error.
After changing to debugmode I got this from the debugger:
log3: EditCurrentRecord Bean : execute() - field name ... Ergbeschlog3: EditCurrentRecord Bean : execute() - field Ergbesch has sNewValue ... test101log3: EditCurrentRecord Bean : execute() - **** Updating Attribute: Ergbesch new value is test101[1235] OracleSQLBuilder Executing doSelect ...

ORA-01002: fetch out of sequence
In the jdbc FAQ writes:
Error Message: "ORA-01002: fetch out of sequence"
A JDBC Connection by default has the AutoCommit turned ON. However, to use a SQL that has 'for update' you need to have autoCommit to be turned OFF.
Hence, the solution is to set autocommit to false.
I'm running the application in stateless mode which has autocommit set on, but I got the same problem running in statefull mode and also I must run the application in stateless mode.
Can you help me. I would appreciate a briefly answer, especially from Huan Oropeza.
TIA,
Seb.

Hi Steven,
let me explain why I need this solutions.
I have a application that has a master detail view from table1 companys to table2 events, so I can have many events to one company. Futher more I have pro event other tables (tableevent1, ... tableevent2) where I have properties of a event recorded, so event1 has properties1, event2 some other and so on ...
Companys -----> Events ------> Event1properties
In my application logic when I create a new event typ I have to create a new table where I will save the properties for that event. So, because the events can have different properties I can not create this in BC4J AppModule.
With VO I have created a ViewLink beetween Company and Event. For data manipulation of the tableevent1 ... I extended the RowSetBrowser thus when changing data to do:
UPDATE ..... statements and SELECTs to get that data.
I have also implemented this kind of operation for the DDL of the tableevent1 ...
(event properties) so this time to get that data I use :
select * from "SYS"."COL" where TNAME=tableevent1;
Changes are done with DDL Statements:
ALTER TABLE ...
CREATE TABLE ...
My problem is when I changed something with the RowSetBrowser methods in the tableevent1...(properties) I can not futher make any inserts, edits using the EditCurrentRecord Bean in the events table (detail table of company).
Please help me with this !
TIA,
Seb
