Master on a View and Detail on a Table

I have a master form and a detail tabular form attached to it - together, on the same page. Form is based on a view and the tab form is based on a table. Whenever an update needs to be done, then on the tabular form - detail record.
If I try to create a new detail record it works fine and saves it. If I want to delete it is fine as well. The only thing that doesn't work is applying changes to an existing record. It fails with the following message:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "9F37DC19F8CD77C45A33036B7E423248", item checksum = "30DA90A7EFF6043FDCBB542183ACE8BA"., update "DEVELOPER"."SYN_LOG_MANIFOLD_PLANING" set "PRIMKEY" = :b1, "ORDER_NUMBER" = :b2, "S_GROUP" = :b3, "MANIFOLD_SHAPE" = :b4, "LENGTH" = :b5, "WIDTH" = :b6, "HEIGTH" = :b7, "NOZZLE_QTY" = :b8, "NOZZLE_TYPE" = :b9, "ZYLINDER_QTY" = :b10, "ZYLINDER_TYPE" = :b
I think I have seen this befor, but still couldn't find the answer. Any ideas?

Got to answer my own question myself.
I found the problem to be in a column included in the tab form. In the report atribute it was set to hideen. However, in the properties of the column it was still saying Tabular Form Element / Display as: Date Picker...... Usually no problem. But in my case, this column is updated by an on insert trigger, which inserts the record creation date. I assume that this is the reason why the error popped up when I tried to update the record. As soon, as I removed the column from my query or set it to hidden, my form was working.

these two canvases opening in separately in layout editor...how i can show them both in one window..???
Please some advice on this ..
Thanks,

Hi
these two canvases opening in separately in layout editor...how i can show them both in one window..???it's just a matter of x & y issue ; pls increase the y position of the tab canvas to move it downward (straight lower down the content) minimize the tab w & h if necessary just for temporary adjustments form design.
By this way u would control the design layout of the two canvases.
Hope this helps...

OC 3.0 SP1 Multiple incumbents data merged in Pos View and Details Panel

In OrgChart 3.0 SP1 we have some instances where there are multiple holders for a position (e.g. 2 people job sharing at 50% each). For all employees the requirement is to display additional data for Employee Group/Subgroup (text), Payscale (Basic Pay IT0008) as well as the standard position/org unit information. For multiple incumbents there are some negative impacts to the data display and any suggestions on how to resolve these issues would be very welcome.
1. Details Panel
If additional fields and data elements are added using the Admin Console, for multiple incumbents the data for each employee displays without distinguishing clearly which employee the data belongs to. So the first employee's name appears, followed by all data for all employees below.
Alternative approach was to try to display the data through the Employee Profile (as separate Profile tabs appear for each employee) by editing the XML files. However, the Profile seems to regenerate in such a way that the additional data for both employees appears in the first employee tab and the 2nd employee tab only contains the basic standard position-org unit information.
What is the best way to distinguish each set of data for an employee in the Details Panel?
2. Position Box View
In the Position Standard View the box shows "Multiple Incumbents" instead of the specific employee names (although these appear if you mouse over). To list the names separately within the box, in a previous post we had the suggestion to modify the template file. However, on closer investigation there appear to be approx 500 instances in 40 files for the relevant views that may need modification.
Is there a more targeted way to do this?
I would be very interested to know how others have configured / dealt with the data for multiple incumbents in their org charts and details panels.
Thanks
Clementine

Hi Clementine,
I hope all is well down under
1. This is a known bug that is resolved in SP2. If you cannot upgrade to SP2 you can delta-merge the changes into SP1, although this is not so easy for the unexperienced. OSS might be able to provide some comprehensive instructions, but I would advise to upgrade to SP2 if possible (although, again, if you've already configured or customized any part of the Position or Employee details then you need to delta-merge the changes anyway).
2. This is standard functionality in the Organization Structure with linked Positions. The alternative is to use the Organization Structure that has linked Employees instead. This will display the structure as you are expecting it.
Let us know if you need more assistance.
Best regards,
Luke

Month view and detail view show different times

I'm importing this calendar:
http://www.mychurchevents.com/calendar/ical/2330512/public.ics?tz=z88
Here is my problem:
The meeting shows in Month view as 10AM, but the details show 9AM. 9AM is the correct time. It's only a problem during Daylight Savings Time. I've switched every Time Zone Control I can find with no change, and I don't want to have to change each event.
This calendar imports perfectly on any iOS device. This is only an issue in the Calendar app on OS X Mavericks.
Feel free to import the calendar and work on it.
Thanks!

Robert,
I imported the calendar, and duplicated your observation, until I edited "to:" to display a 1 hour event. I also used my time zone.
My Screen Shot displays a one hour event which displays the correct start time as follows:

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.

Refresh problem by combination of programmatic view and master-detail page

I am using the latest versions of both ADF (10.1.3.2.0.4066) and JHeadstart (10.1.3.1.26) and I have an application with 1 page in which I have as root page a programmatic view (table-form) which I fill with request parameters.
Under that programmatic view I have a master (table) with 3 detail pages (table).
The programmatic view is populated with always 1 row, which goes always correct.
The problem is occuring when iterating through the first entity based master table which contains lots of rows. Then the problem is that when you navigate through the master table the detail pages are refreshed correctly, but when you navigate back to the first row that row won't get updated.
The next thing I tried is create a new jheadstart application with only the master-detail pages (entity based), so without the programmatic view, and then the iterating through the master table and the refresh of the child tables is working correct.
What can be the problem here.

Have you tested this in the ADF Business Components Browser? That's the tester that you can find by right-clicking your ADF BC Application Module and choosing Test. If you go to the View Object instance for the programmatic view, and using the ViewLinks to its children, do you get the same behavior as in the JHeadstart application?

Creating a master-detail relation between a view and a table

Hi all,
I have a problem with creating a master-detail relation between a database-view with lots of customer data and a small table with per customer a list of entities of our companies who may work for that customer.
Somehow I seem to be unable to create a relation between these two. I can't find where I can make a foreign key using Toplink to implement the relationship. And neither can I get a Viewlink object doing the job using ADF Business Components.
Somebody any suggestions on this problems?
Regards,
Birgit

There is a key relationship between two fields which form the primary key in the main table of the view and two fields in the second table.
I created a viewlink manually, but I still couldn't get the data correct i.e. a form with one record of a customer from the main view and a small table with all entities of our company who can make performances for that customer.
I tried to find a manual or a how-to on this topic but I didn't find anything helpfull yet.
Regards,
Birgit
After a couple more tries, I got the master-detail working. With all the fiddling I am not sure what caused the problem but I think the finally action was checking which fields of the view were marked as primary keys.
Now everthing is up and running.

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:
http://stackoverflow.com/questions/9320638/how-to-pass-an-object-when-navigating-to-a-new-view-in-prism

How to set the display ratio of master and detail view

Currently, I use SplitApp that contain the master and detail view. And I would like to show the master view on the left half and detail view on the right half. Is there any proper way to adjust this?
Thank you in advance.

You can set the width ratio by adding css. Check this,

Please help me with inputs on how to have "SHOW ALL" feature,
Currently, we have to click on ":Show" for each record at master level to view the child data.
Trying to achive "Show All" Feature so that on click of this the master records on the page 'Expands" showiing all master records with respective detail records.

bhuvanm

Hi,
You should not set DetailFlag = "Y" in whereclause because there is no such record.
Also detail flag is transient attribute and not the query column, hence the error "Invalid indentifier".
I asked you to use DetailFlag as query column with static value "Y".
for example:
SELECT "Y" detail_flag
FROM <table_name>
This will display all the table records in expanded format. if you want it conditionally then use decode on some bind parameters.
For example:
SELECT DECODE(:1, "SHOWALL", "Y", "N") detail_flag
FROM <table_name>
This bind parameter should be passed whenever you want to execute query for the table.

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.

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.
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
Tom

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.

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.
