Failed to insert both in master and detail tabels

Hello everyone,
I have a form with a master-detail relation between two data blocks. The master data block gets data from a view (of two tables). Insert in this block alone works.
If I add a record in master block and one in the detail block than, when I save changes, I get the following error:
ORA-02291: integrity constraint (MASTER_DETAIL_FK) violated - parent key not found.
The MASTER_DETAIL_FK constraint is set on FK column from detail table and references PK column from master table.
It looks like Forms try to insert first into the details block and than into master block, but I can not control this. In addition, if the master block is based on a table (not a view), I can add both a master and a detail record and save works ok.
I'm looking forward to a solution to this problem.
Best regards,
Lucian

Master and detail in the same page

db11xe , apex 4.0 , firefox 24 ,
hi all ,
i am trying to insert the master and detail data in one step in the same page :
i have two tables (clients) and (tests_administered)
the client table's region contains theses items
client_id
client_name
the other table's region contains these columns -- the tabular region
row selector
test_admin_id -- pk, hidden
client_id -- hidden , this is the one i should populate with values
and more columns
i've done this :
1- removed the condition of the tabular region .
2- Added the request CREATE to the list in condition of the APPLYMRU process -- or :request like ('CREATE')
3- Added new process with following code : -- with sequence before the applymru process and after process row of clients process
for i in 1..apex_application.g_f02.count
loop
apex_application.g_f02(i) := :p2_client_id ;
end loop ;
but nothing happened . why ? what did i miss ?
thanks

Hi,
Create a Master Detail Form through the APEX Wizard
Make sure you choose the Primary Keys for the Master Detail as one of your Column and not the ROW ID.
Selecting an existing Sequence for the Primary Key is preferred.
Select the option the where your Master and Detail appears in the same page.
Initially when you run the page your master and detail will not appear at the same time in the page when your Master Detail Form is in the entry form mode. For this you have to go to your Tabular Form(Detail Form) region, and below you will have to remove the Condition for the display of your Tabular form and set it to “No Condition”.
Now when you run the page both the Master and Detail form will appear together in the create mode but you will not be able to insert or create both master and detail records at the same time when u click the create button. For this the following needs to be done: You need to create a PL SQL Tabular Form process :
Let's say your master form is based on DEPT and your detail tabular form is based on EMP. Make sure the following things are configured:
The DEPT insert/update DML process runs before the new tabular form PLSQL process. (ie) the new PL SQL Tabular Form Process that you create should be inbetween Automatic Row Processing(DML) and Multi Row Update Process , so create the new Tabular Form Pl SQL process with a sequence number inbetween these two Processes.
Make sure you choose Tabular form while creating this PL SQL process.
The new tabular form PL/SQL process executes the following as the source
:DEPTNO := :P1_DEPTNO;
Where DEPTNO is the Foreign Key column in the Tabular Form that links the Primary Key Item P1_DEPTNO of the Master Form.
Finally this new PL SQL process conditionally runs when DEPTNO is null, so you need to add the following condition to the process:
The final step to accomplish in creating both the Master and Detail records at the same time is to make a change in the condition of the Multi Row Update Process. :request in ('SAVE','CREATE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%'
-We make this change so that records get inserted into the Detail table when we click the ‘’Create” button.
Now you can Run your page and create both the Master and Detail records at the same time.
Thanks and Regards,
Madonna

How to insert new records in Master and detail Forms.

Hi,
I am having trouble inserting values in both master and detail view at the same time. The scenarios is I have a Dept Table (View Object-VO1) and Employee Table(View Object -VO2) both linked with a foreign key, as per Default HR schema in Oracle DB XE.
Now I want to insert new record in both Dept(VO1) and EMP(VO2) table via a New page say ( Page2 ). There is a button on Page1 with button INSERT .I can only drag-drop "CreateInsert" operation on that button for VO1 or VO2. So only text box for Dept records are enable to insert data but not Emp records. Is there a way I can insert data in both the tables at the sametime??
Thanks,
MB

Hi MuradRabbani,
You can programmatically call both createInsert Operations,
Add to your pageDef both CreateInsert Operations.
Create a button tha will call insert method from Master (VO1) and then call insert method for Detail (VO2)
Here is an Example code of calling the operations:
DCBindingContainer dcb = ADFUtils.getDCBindingContainer(); //you need ADFUtils.java and JSFUtils.java classes. You can find them in the sample applications in your JDeveloper.
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO1");
oper.execute();
-----------------NOTE: at this point you should have set values that compine the ViewLink on the master in order the detail will know where to link the new record there are many ways to do it.
As an approach try to overrdi the create Method on the in the ViewRowImpl of your Master vo (VO1)
e.g.
@Override
protected void create(AttributeList attributeList) {
//before
attributeList.setAttribute("NameOfAttribute", valueHere);
super.create(attributeList);
After that you should call the operation for your detail VO2
e.g.
DCBindingContainer dcb = ADFUtils.getDCBindingContainer();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
oper.execute();
The detail record will now have the values from your master automatically.

Dimitris.

Insert Master and Detail in the same transaction

I have 2 view objects : Students and Enrollments.
Connecting those view objects, there is one view link :
Cardinality : 1..* (One student can enroll several courses).
This link is exposed in "Students" view object by the property "getEnrollments" and in "Enrollments" view object, by the property "getStudent".
I am try to insert records first in Student table, and Enrollment table in the same transaction.
The primary key for Student table is generatade by a sequence (database trigger)
My code is :
StudentListImpl studentView = getStudentList();
StudentListRowImpl studentRow = (StudentListRowImpl) studentView.createRow();
studentRow.setFirstname(student.getFirstName());
studentRow.setLastname(student.getLastName());
studentRow.setDatebirth(student.getDateBirth());
studentRow.setStatusid("A");
studentView.insertRow(studentRow);
EnrollmentListRowImpl enrollmentRow = (EnrollmentListRowImpl) studentRow.getEnrollments().createRow();
enrollmentRow.setCourseid("C-100");
studentRow.getEnrollments().insertRow(enrollmentRow);
The generated Student ID is not being retrieved by ADF and set up in Enrollment view object. So, database is firing foreign key violation (in Enrollment table - No student ID provided)
How can achieve this goal? Insert in DETAIL table with the key generated for the PARENT table?

Yes, ID attribute in Student EO is DBSequence.
If I insert only Student it works. But when I try to insert an Enrollment for that just created Student (same transaction), the Student ID is not assigned to Enrollment EO.
The code I use to insert Enrollment is :
EnrollmentListRowImpl enrollmentRow = (EnrollmentListRowImpl) studentRow.getEnrollments().createRow();
enrollmentRow.setCourseid("C-100");
My question is :
Since I am creating a new Enrollment row using view link acessors in Student VO (getEnrollments), will the Student ID (just generated by sequence) be automatically assigned to Enrollment VO?
I am totally lost about this (inserting master and detail in same transaction) and I can't find documentation on this topic.

Insert master and detail rows with Composition assoc generating JBO-26048

I have the Master and Detail Entity Objects and made an Association linking them as Composition related.
I have 2 ViewObjects. the MasterViewObject is composed of the Master entity object and 1 other udpateable object. the DetailViewObejct only contains the Detail entity Object.
I tried to create a row on the masterviewobject and then immeidately create a detail row, and then commit, ADF issues a JBO-26048 error. Constraint "MY_FK" violated during post operation.... ".
I don't know wahts wrong, but this should not be error should nit be appearing, as ViewObjects and the Links with Composition Association take care of populating the Foreign Keys of the detail. Or am I missing something here?

The ADF Guide covers this problem, and I have a method that works as well on jdevguru.com. Take a look at the manual first, they have an indepth view on it and how to get it all to work together.

Displaying the master and detail records ....

Hi ,
There is a master - detail form. The end-user make some insertions/updates in the detail block...
How is it possible to display these detail records and its master when the user presses a custom button 'refresh' which just requery the records in both master and detail blocks...?????
When i write "to display these detail records and its master " i mean that the current record (the one which the cursor would be focused in ) would be this master record... however,all other records would be displayed as well....
Many thanks,
Simon

From what I understand you want to re-query and go to the record where you were just before re-querying??
Interesting requirement, why you wanna do this? if for the user to see the changes of the updates, that is the default behavior.
You can do this in two ways.
1- in your "Refresh" button save the :system.trigger_record in a parameter :parameter.record_num, for the Master block and after the query you do a go_record(:parameter.record_num) .
BEGIN
     GO_BLOCK('EMP'); --Master Block
     :PARAMETER.RECORD_NUM := :SYSTEM.TRIGGER_RECORD;
     EXECUTE_QUERY;
     GO_RECORD(:PARAMETER.RECORD_NUM);
END;2 you can loop through the block with next_record built-in and an exit condition of a key value you saved in a parameter.
BEGIN
     GO_BLOCK('EMP'); --Master Block
     :PARAMETER.EMPNO := :EMP.EMPNO;
     EXECUTE_QUERY;
     FIRST_RECORD;
     LOOP
          EXIT WHEN :EMP.EMPNO = :PARAMETER.EMPNO;
          NEXT_RECORD;
     END LOOP;
END;Tony

Show master and detail viewobjects in the same jsp

I have two viewobjects which have a master-detail relationship (a viewlink between them).
What I want to do is to show both the master and the detail data in the same jsp, i.e for every row in the master viewobject I want to show all the rows in the detail viewobject.
I tried to drop the master vo on the page from the component palette and then the detail vo next to the master vo, but then only the first row in the detail vo is shown on the page. I want all of them to be shown.
Can anyone please point me in the right direction here?
Ps: I'm using JDeveloper version 9.0.5.2
Thanx a lot
Tom

I dropped both viewobjects as read-only tables and they both have the rangesize set to -1.
I think I made myself a bit unclear when asking my question. I do not want a "normal" master-detail view in my jsp where you see one masterrow and all the detailrows. I want my page to show all the masterrows with all their corresponding detail rows listed under the master row.
The pseudocode may look like this:
for each row in MasterViewObject loop
<<display data in MasterViewObject>>
for each row in DetailViewObject loop
<<display data in DetailViewObject>>
end inner loop
end outer loop
As you see I have a double loop here. Is somehing like this possible without "manually" doing all the stuff?
Thanx

MySQL Sytax error with master and detail pages

Master and Detail pages.
I get an SQL error when I click on an Item in the Master
page.
“You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax
to use near 'ID = 16 LIMIT 0, 10' at line 1 “
If I try to open the detail page I get
“You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax
to use near 'ID = -1 LIMIT 0, 10' at line 1 “
I created this pair by simply clicking on Insert/data object/
master detail page.
I have tried this various ways, but always get the same
result.
Is there a bug in CS3?

Sorry I have solved it myself.
I had accidentally put a space in a table header in the mySQL
data bank.
All works well now.

Connect third ViewObject to 2 ViewObjects (Master And Detail) via ViewLink

I have three ViewObjects; 1 Master 1 Detail connected with a ViewLink; i have a third Read-Only (SQL Based) ViewObject which can only be resolved by two bind variables. But the 1st bind variable is on the Master and the second is on the Detail. How can I connect the third ViewLInk to the Master and Detail ViewObjects?

I dropped both viewobjects as read-only tables and they both have the rangesize set to -1.

PRISM Master-Details with navigation between the Master and details view

Hi, I have a Master list with accounts and a Details list containing transactions.
The Master list : has a UserControl (AccountListView) and Viewmodel(AccountListViewModel)
The list is bound to an observable collection of type AccountViewModel and has a SelectedAccount property to get the current selected account. Each AccountViewModel has a collection of type TransactionViewModel.
public AccountListView(IAccountListViewModel viewModel)
//this.DataContext = vm;
InitializeComponent();
ViewModel = viewModel;
public Infrastructure.IViewModel ViewModel
get
return (IAccountListViewModel)DataContext;
set
DataContext = value;
//the viewmodel
public AccountListViewModel(IRegionManager regionManager)
this.regionManager = regionManager;
this.AccountList = GetAccounts(); // gets the list of accounts from another layer
public AccountViewModel SelectedAccount
get { return selectedAccount; }
set
selectedAccount = value;
OnPropertyChanged("SelectedAccount");
And the Details view has a user control(TransactionListView) and a viewmodel(AccountView);
public TransactionListView(IAccountViewModel viewModel)
InitializeComponent();
ViewModel = viewModel;
//this.DataContext = vm.SelectedAccount;
public Infrastructure.IViewModel ViewModel
get
return (IAccountViewModel)DataContext;
set
DataContext = value;
//the viewmodel
public AccountViewModel(Business.Account a)
AccountId = a.AccountId;
accountName = a.AccountName;
I created a hyperlink command so that whenever I click on the name of an account from the master list it will navigate to the detail list and set the as the DataContext the account I clicked on. Before I had both Master and Detail lists displayed at the
same time and set the DataContext of the Detail List as the SelectedAccount property(which is bound to the SelectedItem of the Master List) of the Master List. I am not sure how to pass the SelectedAccount when I navigate to the Detail List and set it as the
DataContext of the Detail List.

>>I'm using the reguestnavigate method, but from what I read you can't pass objects as parameters ?
As I mentioned there is a NavigationParameters class that you can create an instance of and pass as a parameter to the RequestNavigate method in Prism 5:
private void NavigateTransaction(AccountViewModel obj)
var parameters = new NavigationParameters();
parameters.Add("accountViewModel", obj);
regionManager.RequestNavigate(RegionNames.ContentRegion, new Uri(transactionview, UriKind.Relative), parameters);
The TransactionView should then implement the Microsoft.Practices.Prism.Regions.INavigationAware interface and retrieve the parameter in the OnNavigatedTo method:
public partial class TransactionView : UserControl, INavigationAware
public TransactionView()
InitializeComponent();
void INavigationAware.OnNavigatedTo(NavigationContext navigationContext)
AccountViewModel myParameter = navigationContext.Parameters["accountViewModel"] as AccountViewModel;
this.DataContext = myParameter;
public bool IsNavigationTarget(NavigationContext navigationContext)
return true;
public void OnNavigatedFrom(NavigationContext navigationContext)
In Prism 4 there is no NavigationParameters class so you either need to upgrade to Prism 5 if you haven't already done so or you could store the parameters to be passed yourself somewhere else. Please refer to the following links for more information and
examples of how you could do this:

Master and Detail records in the same table

Hi Steve,
I have master and detail address records in the same table (self-reference). The master addresses are used as templates for detail addresses. Master addresses do not have any masters. Detail addresses have three masters: a master address, a calendar reference and a department. Addresses change from time to time and every department has its own email-account, but they refer to the same master to pre-fill some common values.
Now I need to edit the master and detail address records on the same web page simultaneously.
My question is: Can I implement a Master-View and Detail-View which refer to the same Entity-Object? Or should I implement a second Entity-Object? Or can it be done in a single Master-Detail-View?
Thanks a lot.
Kai.

At a high level, wouldn't this be similar to an Emp entity based on the familiar EMP table that has an association from Emp to itself for the Emp.Mgr attribute?
You can definitely build a view object that references two entity usages of the same entity like this to show, say, an employee's ENAME and at the same time their manager's ENAME.
If there are multiple details for a given master, you can also do that with separate VO's both based on the same entity, sure. Again, just like a VO that shows a manager, and a view-linked VO of all the employees that report to him/her.

How to create one Oprations button (Create Button Or CreateInsert Button )for all master And Detail block?

hi
I have master And Detail with 4 level ,I want to have on operations button for all block in data control .
(similar to Oracle form toolbar)
how to do it ?

Well, if you tell us your jdev version and what exactly you try to do, without just telling us 'as in forms' we might be able to help.
Most of us don't know how it's done in forms. So be specific when you describe your use case.

Master and details based on business component

Hello,
I search sample Application master and detail based on business component. how build model and View please any one know link show that step by step thank you.

Hi
http://docs.oracle.com/cd/E18941_01/tutorials/toc.htm
there is not much into it really...
you just select your model project, right click and select new and in the wizard, choose Business Components from tables.
You should, at least have a database schema with at least one PK and FK declarations.
the wizard will take care of everything else.

Hello!
you have ti create a Master/Detail data structure.
In the first page drag the master table, on the second drag a detail table.
It should work out of the box. Selecting a record on the master table selects
