Dropdown values becoming null after deployment

Question

Iam using jdev 10.1.3.4 and oc4j 10.1.3.4 server.
we have a ADF table in a page in the application with three dropdowns. when i run the page in jdev the values are getting populated correctly for every record.But After deployment, for some records the values in the dropdowns are becoming null. we have 85 records in our Database for which only 5 records have this problem after deployment. But this works fine in local server.
Any help will be appreciated.
Thanks,
Lakshmi.

Thank you very much for answering...
I can't send all the code because it needs plenty of files to run. I'll just describe the "critical" parts of it:
- my main class extends JPanel and implements ActionListener + FocusListener + ListSelectionListener
- the JTable is declared by private JTable myTable = null;
- the table is inited by a call to a private void method, with the followind code:
   myTable = new JTable(cellData,colNames);
   myTable.setName("my_table");
   myTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
   //... - the table is then put in a scroll pane:
   sTable = new JScrollPane(myTable);and the scroll pane put in the NORTH of a JPanel.
- I put a listener on the table by:
   myTable.getSelectionModel().addListSelectionListener(this);Here is the most part of the misfuntionning code... the table goes well until the listener generates events... then the myTable instance becomes NULL.
Thanks in advance for thinking about the problem's causes,
Cheers.
