LOV gives jbo-25013 in 9.0.3

Question

Hi,
We have migrated our project from 9.0.2 to 9.0.3 (preview 988). In our
JClient we have a button lov-binding to select a new record in
the form.
If we try this JClient in 903, selecting another record in the lov-window
gives this error
(oracle.jbo.TooManyObjectsException) JBO-25013: Too many objects match the primary key oracle.jbo.Key[FDO ].
But it is even worse now, because it is not posssible to create this LOV-binding
with a new JClient project created in 903 (also the bc's are new).
I choose in the JClient LOv-binding wizard the lov viewobject the same
as the target viewobject. Add the attributes for the object binding.
In this way it was possible in 902
to have a lov for selecting a new record. This worked fine.
Any suggestions?
regards,
Richard

Okay, I hope this is enough information
We have a Jclient Form of employees. One record shown at the time.
I do not want to create a new record,
but navigate to a employee which I like to select from an Lov window.
To create this functionality in 902 I added a button to the panel and
used to lov binding wizard. I selected the employee vo (CasMedewerkerView)
for the lov viewobject and also in the target viewobject is
selected the employee vo.
I used two fields for the LOv/Object binding. The following code
was generated.
jButton1.setModel(JULovButtonBinding.createLovBinding(panelBinding
, jButton1, "CasMedewerkerView", null
, "CasMedewerkerViewIter"
, new String[] {"Afkorting", "Naam"}
, "CasMedewerkerView"
, new String[] {"Afkorting", "Naam"}
, new String[] {"Afkorting", "Naam"}));
The field Afkorting is primary key for this table.
If I runtime pressed the button a LOV window showed up and I could
select an employee and after selecting, the fields in the JClient
were filled with the data belonging to this employee.
Now if I run this project with jdev903, i receive runtime the error
JBO-25013: Too many objects match the primary key oracle.jbo.Key[FDO ].
Then
I builded from scratch a new BC and a JClient Form in 903.
I used the wizard in the same way as i did in 902.
Selecting the same Vo for the lov viewobject as for the target viewobject.
The code generated is:
jButton1.setModel(JULovButtonBinding.createLovBinding(panelBinding
, jButton1, "CasMedewerkersView1", null
, "CasMedewerkersView1Iter"
, new String[] {"Afkorting", "Naam"}
, "CasMedewerkersView1"
, "CasMedewerkersView1LOVIter"
, "CasMedewerkersView1LOVIter"
, new String[] {"Afkorting", "Naam"}
, new String[] {"Afkorting", "Naam"}
, false, "", null));
If run this example I receive again the error, Jbo-25013
Moreover, if i close Jdev and restart, then in the property model
of the JButton my Jclient Lov binding is gone.
If I now replace the code "CasMedewerkersView1LOVIter" ,as
suggested, by Grant Ronald with
CasMedewerkersView1Iter the Jclient runs like I want, and no error
appears.
Is the wizard generating wrong code or do I use
the wizard incorrectly to have the functionality as I described?
