Problem with master/detail relationship

Two tables :
Master_table:
Customer_no primary key
Buyer_seller_type primary key
Product_code primary key
Detail_table
Branch primary key
Customer_no primary key
I altered detail_table and added 2 more primary key fields:
Buyer_seller_type primary key--
Product_code primary key.
Now I have to change the existing fmb according.
I have maintained master/detail relationship for these 2 tables in the form.
When I run this form and Try to save the date . I am getting error like
Cannot insert null into buyer_seller_type field ie my new column.
Insert into detail_table (branch,customer_type) values (:1,:2) ;
I have maintained master/detail relationship. And what r the others properties I have to set to overcome this .
my requirement is query should be like this:
insert into detail_table (branch,customer_type,buyer_seller_type,product_code) values (:1,:2,:3,:4) ;
how can i do this.
I am using forms 6.
plz its very urgent..plz help me.
advance thanks

Set following item property under Data node for both the new added column in detail table:
Copy Value from Item:
Enter <master_table_name.item_name>

Can anybody give me any idea how to sort out this problem.

If possible can u give me any live example for this

I think the detailDisclosure state needs to be saved and retrieved from the session.
I'm not sure using a table with singleSelection inside a detail disclosure is supported. Are you doing master-detail inside of detail disclosure? Detail disclosure is not really meant for that. In jdev 10g preview we make hooking up a master-detail easy. Here's a link to some doc about it.

Problem with Master -Details forms in seperate pages

Hi ,
Below is the scenario:
I have Institution and a department tables where there is a foreign key relation between the tables. So now i have two entity objects for the 2 tables and 2 view objects(DepartmentView,InstitutionView) from the entity objects.
I also have a view link between them.I made a master-detail relation between them in the datamodel using the view link.So my appmodule now has getters for the department view,institution view and viewlink.
I now have a jsp page "createInstitution.jsp" which contains a form for the institution , i have a "next" button on the same jsp which calls a method in my appmodule class .This methods just inserts the record into the Institution view. In this method i am able to see what the user entered in the form by getting the viewrow record like the below code :
InstitutionViewRowImpl newInstitutionRow=(InstitutionViewRowImpl) getInstitutionView().first();
The next button navigates to the next page "listDepartments.jsp" which contains the list of departments that are added. This page has a button "Add Department" which takes to to the "addDepartment.jsp" page which shows a form for adding a department. This page also has a button which calls a method in app module class. The method just inserts the record into the view(DepartmentView)
Here when i say
DepartmentViewRowImpl newDepartmentRow=(DepartmentViewRowImpl ) getDepartmentView().first();
the newDepartmentRow is null.
Also on the addDepartment.jsp form , i had used a output field to see what the parent id was and interestingly the parent id is 75 which is first institution in the database. It should have been "-10" , a temporary id assigned.
Can someone please tell me what is the problem with my approach?

I don't understand why you are using a method on your button to insert the record into the table - An Oracle ADF Form will do the insert for you by default without any coding.
See the create pages in these tutorials:
http://www.oracle.com/technology/products/jdev/11/cuecards/adf_set_21/ccset21_ALL.html
http://www.oracle.com/technology/obe/obe11jdev/11/dev_ui/developuserinterface.html#t2s5
The method that you are calling just returns the first record in the rowset - I don't see how it has anything to do with actually inserting the data into the table.

Problems with Master / Detail created in backing-bean programmatically

We are developing with JDeveloper 10.1.3.3 and ADF.
We have 2 jspx.
In the fisrt one we select some information and we create the master/detail in the backing-bean programmatically using createRow() and insertRow() in both ViewObject.
In the second one we have the master/detail table.
The problem is that when we go to the second jspx only appears the master row, no the detail row.
Otherwise if we only create a detail row (belonging to an existing master) in the backing bean of the first jspx then the detail rows are shown correctly.
Thanks in advance.

Hi,
you need to give more details on the implatementation. If you use ADF binding then just as a heads up: operation against VOs directly is far away from best practice

Problems with Master-Detail Form not retrieving Detail Rows

Portal 3.0.7.6.2 on NT
I am having problems with a Master-Detail Form not retrieving Detail Rows. Sometimes it retrieves all, sometimes about 50%, the majority of the time it's not retrieving any. If it never retrieved any I would suspect that the 'join' condition was wrong but that isn't the case. I didn't have this problem with a prior MD Form I created. I have tried re-creating the MD Form but I get the same problem.
Is anyone having similar problems/is this a know bug??
Any help or thoughts are appreciated.

I experienced performance problems. The simpiest MD form takes about 10 secs. to requery. I's not answer to your question, but there is more problems with this concept.

Problem with Master-Detail web page tutorial

My student asked me about this problem:
I just completed the following Master-Detail tutorial...
http://www.oracle.com/technology/products/jdev/collateral/4gl/HO_Workshop/hos1_1/HOS1_1_ADF_Forms_Designer.pdf
... The problem here is that when I try to define Order By CUSTOMER_ID in CustomersView the App Module test and the application both fail...
JBO-30003: The application pool (model.OrderEntryAMLocal) failed to checkout an application module due to the following exception:oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.domain.DataCreationException, msg=JBO-25029: Data class (a domain?) String not found at oracle.jbo.JboException.<init>(JboException.java:343) at oracle.jbo.common.ampool.ApplicationPoolImpl.doCheckout(ApplicationPoolImpl.java:1772) at oracle.jbo.common.ampool.ApplicationPoolImpl.useApplicationModule(ApplicationPoolImpl.java:2611)
(etc...)
Note that I can define Order By ORDER_ID in OrdersView without problems.

Thanks Frank... I had entered just CUSTOMER_ID as you said. After trying this, the App Module is "permanently" broken. It will not work again even if I remove the Order By entry. I was able to use Order By ORDER_ID successfully in the OrdersView. The Order By is not part of the tutorial, but I wanted to use it because I would if this was a real application.

Performance Problem with Master-Detail Views

Hi,
I have developed a JSP-Applikcation with the master-detail views.
I would like to report a bad performance at fetching data records from the detail view, because all records
from master view have firstly to be retrieved to locate right row (rangesize="-1"). The number of records in
the master table ist 2500 and 7000 in detail table.
============= Code Snippets (See HOWTO:Navigate using Data Tags of J. Oropeza) =====
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" rangesize="-1">
<jbo:RefreshDataSource datasource="dsMaster">
<jbo:Row id="msRow" datasource="dsMaster" action="Find" rowkeyparam="RowkeyValue">
<jbo:dataSource id="dsDetail" appid="testAppId viewobject="DetailView">
======================================================================
When rangesize="20" sets, performance is good, but the right row location of master view ist not found if the row
is not positoned in this range (No data from detail view object are displayed).
How can I improve the performance?
Many thanks for your help.
regards,
Yoo

Sung:
Thank you for your suggestion.
According to your suggestion I have changed my BC4J/JSP-application. However, the performance ist still bad.Whenn I click on a row retrieved from the master view, it takes 15 seconds until the associated data in detail view will be displayed on the other window (The application has been deployed on the test system of ISP).
In an other case with much less data (162 master and 228 detail rows), it takes only 2 seconds (The application
goes with the local server and DB of our company).
======================== master.jsp =================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView" >
<a href="detail.jsp?RowKeyValue=<jbo:ShowValue datasource="dsMaster" dataitem="RowKey"/>">
Here Click
</a>
======================== detail.jsp ======================================
<jbo:DataSource id="dsMaster appid=testAppId viewobject="MaterView">
<jbo:RefreshDataSource datasource="dsMaster">
<jbo:Row id="msRow" datasource="dsMaster" action="Find" rowkeyparam="RowkeyValue">
<jbo:dataSource id="dsDetail" appid="testAppId viewobject="DetailView">
How do you think of this coding (My application is based on the document How to of J. Oropeza)?
How can I increase the performance independently of the number of rows?
Many thanks for your help.

Master Details relationship

I have an application where I need to have master detail relationship. I have seen a demo ( dept-emp ) but my requirements are slightly different from this demo.
Just to simplify it, I have these fields in the SD_SOWS which acts as MASTER table and it has SOW ID as primary key.
And I have 2 detail tables. One is used to hold all the handsets (SD_SOW_HANDSETS ) and the other one is to hold all the platforms ( SD_SOW_PLATFORMS ) . And they both are tied up using SOW_ID column ( this is the fk ).
The problem arises when I added a new SOW and I have assigned SOW ID with the new value automatically by changing SOURCE to SQL Query and run this statement below :
SELECT NVL( NEXTVALUE ,1)
FROM (SELECT MAX(SOW_ID) + 1 NEXTVALUE
FROM SD_SOWS
But
1) when I added the one of detail tables ( SD_SOW_HANDSETS ) , this new SOW ID doesn't get carried forward to SOW ID column of this detail table (it becomes blank )
2) If I entered this column manually ( assuming I use the same number as the one in MASTER table -SD_SOWS ) and I have it saved , it throws exception
ORA-02291: integrity constraint (DSSMASTER.FK_SOW_HANDSET_SOWID) violated - parent key not found
I know the reason is that I haven't confirmed and saved the master table yet but I was wondering if HTMLDB can create a dummy SOW ID in the MASTER table and save it temporarily in db where it allows the children / details to reference the same number.
any ideas ?

I'm always getting the same details for all masters rows. any idea what could it be ? Sounds like you didn't set the Block.Query Data Source Arguments property so that your Master block key values are not getting passed to your "Query" procedure. You will need to create a parameter to your procedure for the key value as well. Did you use my Demo or My Oracle Supports? If you used my demo, you will need to modify the EMP_SELECT procedure to accept the DEPT_NO as a parameter and then adjust your query to use the parameter.
If you used My Oracle Supports demo (doc ID 66887.1) then look at Example B. Multi-Block operations with Master-Detail relationship. It shows you how to write the query procedure to accept additional parameters.
Hope this helps,

Problems in Master-Detail forms when the detail contains LOVs

I am having problems with master detail forms when the detail contains and lov.
In my detail form I have a messageLovInput field that returns 2 values (code and description). When the lov window returns both values the messageLovInput disappear from the form.
This problem happens only when I iterate in the master view and I try to add a record in the detail form.
If I add a new record without navigation for the master view there is no problem.

Jode,
which technology are you using, ADF JClient ? If yes, please provide a step by step description of how to setup a testcase to reproduce the problem.

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?
Thanks,

ESB problem when use merge function in master/detail relationship

I have some problem with the merge function in database adapter.
details:
I have 2 tables in master/detail relationship, both have GUID column as a primary key (GUID generated by ESB).
'car_group' table
pk : guid
unique : group_no, datadate, datatime
===============================
guid, group_no, datadate, datatime, group_detail
===============================
1, 1, 01/01/2008, 09:00, groupdetail01
2, 1, 01/01/2008, 10:00, groupdetail02
'car_group_detail' table
pk : guid
fk : car_group_guid link to car_group.guid
==================
guid, car_group_guid, detail
==================
1, 1, detail01
2, 1, detail02
3, 2, detail03
4, 2, detail04
I used a file adapter as a input, here is an example text file
M, 1, 01/01/2008, 09:00, groupdetail01
D, detail01
D, detail02
M, 1, 01/01/2008, 10:00, groupdetail02
D, detail03
D, detail04
Because I used merge function so I need to specify the columns that will be a condition for the insert/update,
but I have generate GUID as a primary key in the tables, I can't used it, so in toplink I map my unique key as a primary key.
The insert operation work fine but when update is required (for example, try to change 'group_detail' column of the master table in text file),
an SQLException thrown, the log file shown the adapter try to update the GUID column of master table but the constraint not allowed.
And yes, cause of GUID generate everytime so ESB try to update this column also, but I don't want to do like that, I need something
like when update operation required, just ignored the GUID column.
I try to mark read-only to the GUID column in Toplink mapping file but still have the same problem, it still generate UPDATE statement
with the GUID column, and also I try to let the database trigger to generate GUID instead of ESB function, but it not works in master/detail
relationship (I think the Toplink manage the relationship, is it right ?)
Please advise, thanks for advance.

somebody please help, thanks !!!

Problem using rollback in master-detail relationship

Hello,
I have an odd error using master-detail relationship, for example: countries and states. This is the problem:
I have 3 pages:
Page A: Read-only table of countries
Page B: Read-only table of states
Page C: State form
and the flow:
1. In the page A, select a country and click button to go to the states page
2. In the page B, select a state and click detail button to go to the state form page
3. In the page C, edit something and click rollback button. The rollback button's action goes to the page B
4. In the page B, the states table is empty but I expected the table contains the same states those were in the step 2
I know it's a bit difficult to understand but I hope someone can help me.
Thanks, edwin.

On invoking Rollback the whole of AM is refreshed and hence all VOs are refreshed. The first row in all VOs is selected by default. You will need to retain the VO row selections on your own. Check this thread for ideas.
Stay on previous or next row on rollback.

Displaying a Master Detail Relationship in a Panel Accordion or Tabs

Hi,
Is it possible to display a Master-Detail relationship in a Panel Accordion or Panel Tab or other component that visually divides the display?
Say I have a Department - > Employees master detail relationship and I want each tab in my accordion to represent each
departments and when I clicked the tab, the list of employees associated with that department is displayed.
I am exploring this idea but I cant get to find a resource on how to move forward. I am using JDev 11.1.1.4. Thanks

Hello,
I recently faced the same problem and did not find a clean solution either. So I implemented it a bit more "dirty". :-)
Instead of using the Department > Employee view link, I just created a new view object (say EmployeesFromDept), that has a bind parameter called p_DeptId:
     SELECT ...
     FROM   EMPLOYEES e
     WHERE e.DEPARTMENT_ID = :p_DeptIdThe Data Control of this VO will have an ExecuteWithParams operation that takes the department id as input. Create an action binding in your page definition that binds to this operation, called "RefreshEmployeesForDept":
     <action IterBinding="EmployeesFromDeptIterator" id="RefreshEmployeesForDept"
            InstanceName="MyAMDataControl.EmployeesFromDept"
            DataControl="MyAMDataControl" RequiresUpdateModel="true"
            Action="executeWithParams">
      <NamedData NDName="p_DeptId" NDValue="" NDType="java.lang.String"/>
    </action>In your page, add the current DepartmentId to each showDetailItem using an attribute and add a disclosureListener:
     <af:iterator id="i1" value="#{bindings.Departments.collectionModel}" var="row">
            <af:showDetailItem text="#{row.DepartmentName}" disclosureListener="#{pageFlowScope.myBean.toggleDisclosed}">
               <f:attribute name="currentDepartmentId" value="#{row.DepartmentId}"/>
                          <af:table value="#{bindings.EmployeesFromDept.collectionModel}" var="row"
                      rows="#{bindings.EmployeesFromDept.rangeSize}"
                      emptyText="#{bindings.EmployeesFromDept.viewable ? 'No data to display.' : 'Access Denied.'}"
                      fetchSize="#{bindings.EmployeesFromDept.rangeSize}"
                      rowBandingInterval="0" id="t1">
               //Lots of mapping column here
                    </af:table>
            </af:showDetailItem>
     </af:iterator>Now each showDetailItem that is generated knows the DepartmentId it "belongs to". In the toggleDisclosed(DisclosureEvent disclosureEvent) method, first fetch this attribute, so that you know the dept id of the showDetailItem that was clicked. Next, programmatically call the RefreshEmployeesForDept action binding if the current event is "disclosing the showDetailItem":
     public void toggleDisclosed(DisclosureEvent disclosureEvent) {
          String currentDepartmentId = disclosureEvent.getComponent().getAttributes().get("currentDepartmentId").toString();
          if(disclosureEvent.isExpanded()){
               DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
               OperationBinding operBinding = bindings.getOperationBinding("RefreshEmployeesForDept");
               if(operBinding != null){
                    operBinding.getParamsMap().put("p_DeptId", currentDepartmentId);
                    operBinding.execute();
    }Now, each time a showDetailItem is opened, the bind variable of the iterator belonging to your list of Employees will be refreshed with the correct DepartmentId. Ie the department that the showDetailItem represents.
Hope this helps! If you find a cleaner solution, please let me know. :-)

Chris
