JBO-25034 Rollback bc4J/ejb

Question

When I run the jclient application with a local connection it runs without the specified error.
The error only occurs when I run it connecting to the oc4j/ejb.
I investigated a bit and have find out when it was occuring :
I have a JTable :
private JTable tableUsrrolView = new JTable() {
//Override to avoid redundant setValueAt, as Combobox binding will
//set the value on selection rightaway.
public void editingStopped(javax.swing.event.ChangeEvent e)
// Take in the new value
TableCellEditor editor = getCellEditor();
if (editor instanceof DefaultCellEditor )
Component cellEditor = ((DefaultCellEditor)editor).getComponent();
if (cellEditor == jComboBox1)
removeEditor();
return;
else if (cellEditor == jCheckBox1)
removeEditor();
return;
super.editingStopped(e);
//Swing JTable calls this method to get the editor for a cell.
//If the editor is the installed combobox, set selected item in the
//combobox to the value shown in that cell and return the combobox.
public Component prepareEditor(TableCellEditor editor, int row, int column)
if (editor instanceof DefaultCellEditor )
Component cellEditor = ((DefaultCellEditor)editor).getComponent();
if (cellEditor == jComboBox1)
this.setRowSelectionInterval(row, row);
jComboBox1.setSelectedItem(getValueAt(row, column));
return jComboBox1;
return super.prepareEditor(editor, row, column);
//and in the jbInit I do the following :
// (if I don't execute the second line then I don't get the error JBO-27019)
tableUsrrolView.setModel(JUTableBinding.createAttributeListBinding(panelBinding, tableUsrrolView, "UsrrolView1", null, "UsrrolView1Iter", new String[] {"Appabbr", "Rolnam", "Roldsc", "Prcmrk"}));
jComboBox1.setModel(JUComboBoxBinding.createLovBinding(panelBinding, jComboBox1, "UsrrolView1", null, "UsrrolView1Iter", new String[] {"Appabbr", "Rolnam"}, "ApprolView", new String[] {"Appabbr", "Rolnam"}, new String[] {"AppabbrRolnam", "Rolnam", "Roldsc", "Rolpwd", "Dftmrk"}, null, null));
tableUsrrolView.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(jComboBox1));
Is there maybe a workaround to this problem?
I have tried allready the sync(Re: Problem in Failover of Physical standby database to primary but it didn't help me.

Answer 1

Could you elaborate on this please. I was able to insert a new row in a JTable with combobox and the combobox was appropriately populated and allowed me to pick a relevant row.
sorry my mistake, i used the workaround for bug 2394583 as explained in Re: problem: Objects become invalid so easily This code was still in the program and that was causing the problem. So I removed the code : panelBinding.findIterBinding("UsrrolView1Iter").rangeRefreshed(null); And now it works again. (the bug is also fixed:)
Good. Atleast one issue resolved.
(Shouldn't it also popup in the bc4j/ejb implementation? This should occur when you traverse out of the row in bc4j/ejb mode. Let us know the steps to reproduce this.
Just take the example JTableCombo, deploy it as an ejb.
run against the ejb.
create a record
only populate the lov
click on another row.
-> you are able to get the focus on that row(and change it).
-> there is another strange behaviour now and that is when i change the lov of the existing row, the returning values are put in the new row...)
So also in this example the client-server implementation works fine you get:(oracle.jbo.AttrValException) JBO-27014: Attribute DepartmentId in Mypackage1Module.DepartmentsView is required
And the focus gets back to the record you created. Lets take this afresh. Now you have a ComboBox in a JTable.
Bc4j/AM is deployed as ejb.
You create a new row in the table, you drop the combobox down and select some (which I do not think is relevant here) and click on another row.
->That allows you to change focus to another row without any exception - the expected exception is AttrValException for a mandatory field.
DId I miss something here?
I tried this and was unable to reproduce this. When I focused on to another row without filling in the mandatory field, I did see the AttrValException. Also the focus went back to the new row.
I've deployed my BC4J as EJB Session bean into OC4J/Embedded
