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

Detail-Disclosure problem with Master- Detail VO

Hi,
I have UIX pages based on Master - Detail VO, detail data being shown when you press Detail button on the left, detail data display in the BC4J Table correctly, but I am able to update only the last record of the rowset. when I click on the first master detail and press update button i get Null Pointer Exeception error and other problem is that my detail data has sorted headers, when i click on the sorted column header, it close the Detail portion on the Table.
Here is UIX page listing, please any one review the code and let me what is wrong
Thanks

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 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 between 3 tables or more

Hi to the community, I have the following problem.
I have 3 tables relationship : table Solicitud, ItemSolicitado,Cotizacion
Solicitud - ItemSolicitado ( 1 to * relationship )
ItemSolicitado - Cotizacion ( 1 to * relationship )
Solicitud - Cotizacion ( 1 to * relationship )
I have a Master Detail between Solicitud/ItemSolicitado , and it run correctly, I Insert,update,delete correctly ( with expression Groovy )
I want make a master/detail between ( Solicitud/ItemSolicitado ) / Cotizacion , because I need insert some data in Cotizacion table with some data from Solicitud/ItemSolicitado.
The user see the Master/Detail between the Solicitud/ItemSolicitado Tables, and when the user select a item from the detail ( ItemSolicitado ) I want insert data into Cotizacion Table with the Solicitud Primary key and ItemSolicitado primary key
How I can make a Master Detail between 3 tables or more ?? or, How I can do what I want ? some idea ??
Thanks.

I resolved it !!, Only create a view link between the tables and I define in the Data Model Tab of my application module, as following, and it run !!
+Solicitud              // parent
+ItemSolicitado   // child 1
+Cotizacion        // child2

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.

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 create problem

hi,everyone:
Firstly to say sorry for my bad English.
Now I have a question:
I'm working in JDeveloper 10.1.3 .The model layer is SessionEJB /Toplink ,and the view layer is JSF. I have a data structure :
HrUnit : Master
HrHuman : detail
HrKnowledge : detail
the <HrHuman>'s PRIMARYKEY is <ID>,and the <HrKnowledge>'s FOREIGN KEY is <RYID>.
and I want to make a page to insert a new row on <HrKnowledge>. I drag the <hrKnowledgeCollectionIterator> into the page as <ADF Creation Form>, the page run fine.
next step, I make <persistEntity> binding to the <submit button> and the parameters(entity) is
${bindings.hrKnowledgeCollectionIterator.currentRow.dataProvider}.
when i run the page , i get a wrong . i get the SQL in the <Unit of work > is
"INSERT INTO HrUnit ....."
i create a direct mapping for the detail's foreginkey in toplink,and when i "rebuild" the map ,it gives me a warning. This warning affect my custom code in EJB,it can't work correctly. So i can't use this way in my question.
Re: Master /Detail create problem
I beg your help.
Thanks. and very very thanks.

Hi,
I am not an expert in TopLink, but it appears to me that the TopLink model is causes your problems not ADF. There is a TopLink forum here on OTN that could give you a helping hand on this issue.
The following tutorial explains the use of TopLink in ADF

Populate PK(DBSequence) in three related tables with master detail association

Hi
I use jdeveloper 11.1.1.6.0.
My English isn't very good.
I have 3 tables with master detail association between them and primary key from table A should populate to tables B and finally C .The primary key is a sequence from data base and I set PK attribute in table A as a DBSequence. (table C is the child of table B and table B is the child of table A)
My association is like this: A->B(BAFk1Assoc) and B ->C(CBFk1Assoc) and also I select Composition Association for these two association. And I select ‘Cascade Update Key Attribute’
When I insert row in these three related tables, a negative number create but when I COMMIT the PK populate only to table B not to table C and the exception below raises:
Constraint "C_B_FK1" is violated during post operation "Insert"
ORA-02291: integrity constraint (HR.C_B_FK1) violated - parent key not found.
If I only work with tables A and B, there isn't any problem but if I add table C as the child of B, this exception raises.

The question is how you create the row for table C. Do you create it as child from table b (using the VO for B and using the link to C)?
In this case the framework should populate the PK of the master row B as FK in table C.
You may need to control the order in which the rows are posted to the DB to avoid this problem. Read Advanced Entity Object Techniques - 11g Release 1 (11.1.1.6.0) to get more info about this.
However, sometimes it's easier to control the generation and setting if the PK attributes in the model layer, not relating on db triggers where you get the real values only after the commit operation is done in the db. For this you can use a Groovy expression so you have access to the PK of each new created row right after creation. Read Using Groovy Expression to set a Primary Key with a Sequence Number | JDev &amp; ADF Goodies to find out how to do this.

URGENT ! JDEV 10.1.2 Problem with data control generated from session bean

I got a problem with data control generated from session bean which return a collection of data transfer object.
The dto's seem to be correct. The session bean load correctly the data into and the object's are plenty of data. Using the console to display the dto content is ok.
When generating a data control from this session bean and associate the dto included in the collection only the first object level and one-to-one dto object are correctly setted in the data control. Object that represent collection into the dto (one-to-many foreign key) are setted as collection with an iterator but the structure of the object is not setted. I don't know how to associate this second level of collection with the dto bean class to obtain the attributes definition.
I created a case with hr schema like the hrApp demo application in the tutorial with departments and employees table. I got the same problem.
Is it a bug ?
It exists a workaround to force the data control to understand the collection data structure ?
Help is welcome ! this is urgent !!!

we found the problem by assigning the child dto bean class to the node representing the iterator in the xml file corresponding to the master dto.

Not here; updated three systems without issues.
Can you provide more details on your system specs, the projects you're referring to, and what kind of behavior you're encountering?

An inefficient way to create the array is to use the build array and a shift register as shown below. It's more effecient in terms of memory management to create the array and then use the replace array subset as shown in the other image. Of course, if you don't need the array inside the loop, just wire the value out of the while loop and on the exit tunnel, right click and select 'Enable Indexing'.

Problem with Dashboard Details Widget

Hi!
I'm using SCOM 2012R2 UR 4 running og SQL 2012R2 with 3 MS. I have problems with the Details widget on my Dashboards. The problem is that when I select an object, no data is showing up in the details widget - see picture.
I've deleted the "Health Service State" folder on all MS's and restarted them. I've also started the console witn /clearcache without luck.
In addition I've created an SQL maintenance plan running sp_updatestats every 30. minutes, but it
still fails...
What should I do?
Best regards
Rune Haugen

Rune Haugen you are right.
1) try to restart the opeations console with /clearcache
2) try to import the following MP again an make sure that their version number is 7.1.10226.1046
Microsoft.SystemCenter.Visualization.Library.mpb
Microsoft.SystemCenter.Visualization.Component.Library.mpb
Microsoft.SystemCenter.Advisor.mpb
