Help! Master-Detail-Detail problem!

Dear all,
I am using Jdev.10.1.3, ADF + BC.
I have 3 tables: table1(Master), table2(Detail, foreign key set, reference to tabel1) and table3(Detail, foreign key set, reference to table2).
I created an edit form by the following steps:
1) Selected table1 from the Data Control Palette --> Forms --> ADF Form....
2) Selected table3 from the Data Control Palette --> Master-Details --> ADF Master Table, Detail Table
3) Delete the "Submit" button in Master Table
4) Change the "Submit" button to "Delete" (with backing bean) in Detail Table
5) Added 3 buttons (with backing bean) at the bottom of the form (i.e. Save, Delete, Cancel)
6) There is a menu at the top of the form
7) e.g. there are 2 records in Master table and each record contains 3 Detail records
The data retrieve is no problem.
When I clicked the radio button for the first record in the Master table, and then click the Save/Delete button at the bottom of the form. No problem.
However, when I clicked the radio button for the second record in the Master table, and then click the buttons at the bottom of the form.
Duplicate Menu was displayed. Sometimes duplicate buttons were displayed. And the button didn't go to the backing bean.
I don't know why and how to solve the problem??
Hope someone can help me.
Thanks for any suggestion.
Regards.

Hi All,
Just in case anyone has same problem. Since I was not able to get help here I created a tar and we figured that the problem was with the system when I upgraded. System created triggers that were fighting with the sequences that I had manually created.
Disabled triggers and all is working fine. You still need to watch future applications just in case.

Master-Detail Problem SESSION & REQUEST

I'd really appreciate some help with this:
I got a very simple master detail application, with a data table in the master page that gets it's data from a spring-hibernate bean, pretty straightforward.
My business requirement indicates that at first the list will be empty, and after selecting a few criteria values, the list should return with the results(query results).....
I'm using one of the columns with a commandLink tag as usual, to go to the detail page like any number of applications you have seen.
Now the problem arises in that, if my backing bean for my list and criteria is set as a SESSION, everything works fine. However if i set the backing bean in REQUEST scope navigation doesn't ocurr acording to the action and it just redisplays an empty list in the same page (the master list page).....
I changed everything back and forth between sun and apache's releases and nothing...tried a bunch of different things and nothing either...the log doesn't show any exceptions or anything...
Anybody have a clue on this?????

What is the meaning of initialFlag?
If the bean in request scope, when firstly invoking
getPersonData()
the flag is true because queryGenerator() is not
invoked yet in the request.
If the bean in session scope, the value of
initialFlag may hold to be false
since invoking queryGenerator() in the previous
request.initialFlag is just something I use to bring back an empty list
when the action is performed....
However my problem is not displaying the list correctly, is actually Jumping to the detail form (a different JSP) from the commandLink on the datatable results....,
instead it just re-renders the same page (just like if there was a conversion or validation error)
Fragment: From DAO..

Oracle Forms.. Master/Detail problem

Hi,..
I have a problem..
I have 2 blocks in a page. One is an single row block and the other one an multirow block.. master/detail relationship.
I would like that when I change a specifike item in the master block, a column of a specifike record gets changed.
For example:
master block has 3 items.. day, time and weather.
detail block is a multirow block with items.. accessori, owned, take.
when you choise a day and time.. but when you change weather (example to rainy) it goes into the multirow and searches for umbrella and changes the value of column take to YES.
Can anybody help me?
Gr.
Kenneth

Master detail problem in HTML DB

We created a master detail page using master detail page wizard.
But when we create a detail record, master column's values which supporting relation (Foreign Keys) aren't transfered to detail block.
So detail record cannot created. How can we solve this.
Where we can control coordination information between master detail page .
Thanks for your help.

We have solved this problem regenarating FK.
But We are facing other problem too.
when creating master detail form using wizard if we choose "Edit detail on separate page" option the detail page not working correctly
When we try to create detail record " PK value cannot be null" error occurs. It means PK value not transfered this detail page.
It seems like a bug ???
How can we solve it. How can we manually support this Item value.
Thank You.

Master-Details Problem

Hi All
I'm developing a web application using jdeveloper 11.1.2.0
I have Master-Details VOs and have created a Master_details tables in .jspx page. But when I click the master row some time the details will not appear. It remains as in the previous row. This behavior occurs every other click in Master Table.(i.e First master row click then it will display the details rows correctly , then other master row click the details will not get refreshed and so on)
Following error message appears in the log
<CurrencyRowKeySet> <_computeCurrentRowKey> ADFv: rowIterator is null.
Please some one help me on this, I have been searching in google for some days and couldn't overcome from this.

Hi have done those initial things, The problem is MDS configuration. I removed the MDS and it works fine.

Master detail problem

Using jsf/adf with business components.
I have a jsp page which displays form information. This page can be used to create a new record or edit existing record. On the form, there is a section for home addresses and a different section for work addresses. I have a master detail setup. The master record is essentially an employee (view object). Also, i have one view object for Home Addresses and one view object for Work Addresses. The difference is simply in the sql where clause. One retrieves addresses where address_type LIKE 'WORK%' and the other view retrieves addresses where address_type LIKE 'HOME%. So, both views are built on the same address table. (entity object). There is a one to many (master/detail) relationship between employee and home addresses. There is also a one to many (master/detail) relationship between employee and work addresses. So, I've created view link objects for both the home address and work address and associated each to the parent record to get the master detail hooked up. things work great when i'm trying to retrieve and edit a record(s). The home addresses and work addresses are kept separate like they should be and displayed in their appropriate sections on the form. The problem i'm having is with the create record. When the page is first rendered, I want blank input fields to display for both the master record and the detail records. So, i'm programmatically creating the master and detail records before the page is rendered. I create the master row, then create one row for the work address section and one row for the home address section. The problem i'm having is that both of the detail rows which are created this way are displaying in the same work address section. So, when the page is first rendered, i see input fields only in the work address section, and both the rows have been created there, which is evidenced by the fact that i can scroll thru these two newly created records using the "next" button that was dragged/dropped for the work address section. During the create process, it appears (thru debugging) that both of these detail rows are being created properly, with their own separate iterator, so why does it appear that both rows belong to the same iterator when the page is first rendered? I have included the code below which creates the master detail rows:
//this method is called upon the initial entry into the tabbed page if
//user is in "create" mode. It handles creating the master and detail row(s).
public void createMasterDetailRows(){
ViewObject vo = getMasterView();
Row masterRow = vo.createRow();
masterRow.setNewRowState(Row.STATUS_INITIALIZED);
vo.insertRow(masterRow);
//for the initial entry into the tabbed page in create mode, the address row(s) must be created explicitly.
createWorkAddressRow();
createHomeAddressRow();
public void createWorkAddressRow(){
RowIterator iterator = (RowIterator)this.getMasterView().getCurrentRow().getAttribute("WorkAddressView");
Row newWorkAddressRow = iterator.createRow();
newWorkAddressRow .setNewRowState(Row.STATUS_INITIALIZED);
iterator.insertRow(newWorkAddressRow );
int rowCount = iterator.getRowCount();
System.out.println("Address row inserted at " + rowCount);
public void createHomeAddressRow(){
RowIterator iterator = (RowIterator)this.getMasterView().getCurrentRow().getAttribute("HomeAddressView");
Row newHomeAddressRow = iterator.createRow();
newHomeAddressRow.setNewRowState(Row.STATUS_INITIALIZED);
iterator.insertRow(newHomeAddressRow);
int rowCount = iterator.getRowCount();
System.out.println("Home Address row inserted at " + rowCount);
}

Sergio,
You need to set the currency to the row passed in the request parameter from the browse page.
You can used the row tag to do that:
<jbo:Row id="rowCur" datasource="yourMasterDS" rowkeyparam="jboRowKey" action="find">Charles.

Master/Detail problem: Infinite loop with display items

Hi,
I have a strange problem in Oracle Forms 6.0.5.35.3. I create a master block and a detail block with correct relationship between them.
-> When the detail block contains at least one 'Text Item' everything works well.
-> When the detail block only contains 'Display Items', the form is looping
indefinitely calling ON-POPULATE_DETAILS and QUERY-MASTER-DETAILS...
Is it a known bug ?
Do you know a trick to avoid this behaviour ?
Is it corrected with latest versions of forms, I mean 6i ?
Thanks for answer
Laurent Ricci

I think a block should have at least one navigable item. Just disable the insert/update property, but enable the navigable property for an item in the detail block.
Hope that help

A Master Detail Page is a basically a game between two VOs(Master and Detail mostly connected through a View Link). You can also have a look at the View Link section in the Dev guide. Page Layouts is one thing which you can take a call yourself.

Master-details problem: How to access the parent EO/VO in child side?

Hello
Refer to the reply of posting
Re: How to insert new records in Master and detail Forms.
I have got the following questions
The approach for setting the master-details relationship works well, however, in this example,
I have overriden the create(AttributeList attributeList) method of VO2, so after calling
DCBindingContainer dcb = ADFUtils.getDCBindingContainer();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
oper.execute();
, it will enter the create() method of VO2, at this point, i can only access the argument attributeList
which stored the key value that link up parent and child, however, how can i get the entire VO1
for accessing the value of all VO1's attribute?
Thanks

Do you mean that i have to create createRow and insertRow action in blinding layer?No. The createInsert operation does just that
Neon wrote:
Or call these function in the VO overridden create() method?No. You can't do that.
In conclusion, I don't understand why the accessor returns null. Maybe someone else can shed some light... ?:|
One last suggestion from me is to try getting the VO1 directly from the AM instead.
This should work - it is not a recommended practice through.
Use the following code:
VO1RowImpl vo1 = (VO1RowImpl)this.getVO1();
// ensure that the VO1 VL accessor is properly initialized
if (vo1 == null) {
vo1 = (VO1RowImpl)((YourApplicationModuleImpl)this.getApplicationModule()).getVO1().getCurrentRow();

Hi Frank,
Thanks for your reply. In the application I used weblogic JDBC driver for Sybase when it was developed in 11.1.1.1.0 version.
The following are the extries in bc4j.xcfg file:
jbo.sql92.JdbcDriverClass="weblogic.jdbc.sybase.SybaseDriver"
jbo.TypeMapEntries="Java"
jbo.SQLBuilder="SQL92"
Now I have changed the JDBC to Sybase jConnect (jconn4.jar) and driver class is com.sybase.jdbc4.jdbc.SybXADataSource and other entries remains the same as it was before.
Thanks

Master-Detail Problem -ASAP!!

HI
I have a problem that i hope someone can help me with.. I have one JSP page that displays a listing that will either add new,update or delete.. I am using the bc4juix:table tag but the problem that i am getting is that on the other page which is the detail, I have a drop down box that allows me to select a Term of Employment. IT is stored in the database as number.. My problem arises when I want to show on the List page the "string" value of the number. For example, on the list the Term of Employment value shows up in the column on the list page as being "2" BUT i want it to show up as "Unspecified" HOW DO I DO THIS!!!!???

Master/Detail data error problem -- Please Help

Hi All,
I just created a M/D form for two of my tables (Organization & Contact tables) using wizard with existing sequences to create app. Everything looks great when viewing an existing account and making modifications.
My problem stems when I try to create a new account, the Organization form comes up. After entering data and hit 'Create' I get error ORA-01403: No data found. Yet it creates account. Is there a way to get both M&D forms up at the same time with no error after entering data?????
I am too new to know what is going wrong and my manuals do not clarify anything. I'd appreciate any help from a master in Master/Detail forms. :o)
Thanks,

go to the code of your button and change write the following
go_block('name of your master block');
execute_query(no_validate);
and in the object navigator make the first item in the master
block that it should be displayed in the canvas and it must be a
navigable item too.not a display item.
thank you

Master-Detail Relationship problem

I've spent 1.5 days already trying to solve this problem. I'm creating a JClient application using BC4J with a Master-Detail relationship. The relationship between tables is a many-to-many thru an intersection table. I've gotten my master and detail data to show with columnar form data in the top(master) panel and table data in the lower(detail) panel. My problem is that each time I get a master record that contains more than one detail record, each time I click the next navigation button in the master pane it will remain on the master record for the number of detail entries. For example, if a master record has 3 children, then I must click the next button 3 times to move to the next master record. I know that it has something to do with the way the entities are joined but I can't figure out how to join them any other way. Can anyone give me a hint how I can make the master panel only show one record for each Master-Detail relationship (even though the intersection table says its a many-to-many)?
Thanks,
Mark

Apparently, I was making things much more complicated than they needed to be (rather, JDev was). My first attempt at MD relationships, I followed the examples in the help files. JDev created VO's, Entities, Assoc's, View Links, etc... Everything but the kitchen sink! After researching a bunch more, I found that the only thing I needed to do was to create my view objects to display exactly what I wanted to see in my panel regardless of whether it was a parent or a child. Once I had the view objects straight, then I could connect them using a view link and JDev handled the rest. Pretty slick but, I wish there was some better documentation. My next problem is that I'm trying to make this a Master-Detail-Detail-Detail window. The master needs to be a JComboBox, displays only a date, and needs to appear in the same panel as it's child. The 1st child will have a navbar that cycles through a bunch of orders based on the date from the combo box. The order panel's child is in the lower panel and displays the order detail items. It also has a navbar. The lower detail panel needs to have a split pane with the upper part showing the order detail and the lower part showing the materials used in making up that order detail item.
So far, I've got the first 3 parts done (ie. combobox, orders, and details). For the combobox, I used a JComboBox navigationbinding. It shows the correct date, but my control is always disabled. I can't figure out why the combobox is always disabled. The enabled property is set to true. Anbody have any clues?
