Master detail create in jsp

Hi all,
I would like to create a form which is a master and details by using struts.
Order No: 123
Order Date: 12-12-2004
itemsID Qty Price
xxx 12 12
bbb 11 10
Order No and Order Date inputted on the previous screen (jsp)
The user would like to search the order no = 123, then s/he input the details
How can I do on the jsp and actionForm? What is the actionForm includes?
Would you mind give some sample code for me?
Thanks.

Master-Detail in UIX-JSP

Hi:
How can i do a master-detail in UIX-JSP similar in functionality BC4J-JSP?. I haven't found an HOW-TO or guide.
Thanks
Marco

Yes this is easily done.
If you have a BC4J project with say Emp and Dept View Objects which are linked via
a foreign key (there should be a BC4J FKDeptnoLink created), then all you have to do
is generate a BC4J UIX JSP application.
In a separate empty project, open the New gallery and select UIX-JSP -> Business Components JSP Application.
Generate a default JSP application for your BC4J components. You can then run main.jsp
to see the app.
To see a master detail view of your app which is based on the Bc4J Link (FKDeptno) just click
on link "FkDeptnoLink" on the left side..

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

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

Master-Detail Create Page

After looking thru the threads, i didn't see an answer to my specific problem. I have the typical master detail relationship between two view objects. So, i created a view link object to link these two view objects together. What i need to do is from page 1, where the user selects a create button, they are taken to a jspx page that displays in a "new record" (blank inputs) mode for both the master and detail forms. It seems that by dragging a Create button from the palette on the previous page, i can only get a new master record to display or a new detail record to display, depending on which create button i used (from the master or the detail) in the data control palette. Do i need to handle the creation of the master row with it's create button, and then somehow programmatically create the detail row so that when the page appears, i can add a new record for both the master and detail tables? Thanks.

Hi,
usually it is difficult to create a detail record without master, which is why youshould create the master first. Otherwise you may run into situations in which the detail gets updated before the master,with the effect that the master doesn't exis.
I tried coding this scenario in a managed bean, but though teh create form comes up showing both editable, the submit is somewhat tricky. At least you will have to use DB Sequences fro the primary key to ensure the detail is associated to teh correct master.
Not sure if it is worth going this path

Master-Detail: create detail-row(s) with id already filled in

I have two tables with an one-to-many relationship (connected by 'id'). If you select a row from the master-table, you'll see the detail-table (with the various row's belonging to the master-record). Now I made a button which users can use to add additional rows to the detail-table. They get a form which they can fill in and submit, the only problem is... I don't want them to manualy fill in the id, this should be the only field that should already be filled in (or better should be invisible, but filled in). So they should select a master-row first and then click 'add' to add a detail-row(s) to it. But I have absolutely no clue how I can do this... I tried creating custom create methods in the view-object or entity-object... but the problem I keep running into is where to get the row-iterator... I have know idea if this is the right direction to look for, maybe somebody can give me some advice.
Thanks in advance...!

Steven, hope you can help me out once more...
I have the same problem with a different view object, I'll explain...
First of all I set jbo.locking.mode to 'optimistic', now the problem...
I have two entity objects (Mbrships and Mbrshiphistory) which are connected by a foreign key (created in the database) on MbrshipID. Mbrshipshistory is also connected to the Aff entity object by a foreign key on AffID. The idea is simple... there are affiliates and a couple of memberships. An affiliate has/had a membership, that's where the membershiphistory-table comes in, which stores AffID, MbrshipID, DateFrom, DateTo and some other values.
Now, what I created... JDeveloper created entity-objects of all the tables and made associations of the foreign keys. I created the following view objects: http://213.93.142.238/oracle/datamodel.jpg and application module: http://213.93.142.238/oracle/applicationmodule.jpg The (MemberToMembershipHistory) view link between Members and MembershipHostory is based upon the association between the two tables.
The following is a screenshot of my struts-config.xml: http://213.93.142.238/oracle/struts-config.jpg
Editing mbrshiphistories works fine, but I get the following error when I try to add one: oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity. I also don't see the AffID already filled in in the add/edit-screen (same problem as in the opening-post) when I try to add one. I double-checked everything, but I can't find the problem. Do you know what I do wrong...?

Master Detail BC4J /JSP

Hi all,
I am busy developing a small search application.
For this application I use a Oracle View. This Oracle View has no reference to a primary key. In BC4J I created a entity object and view out of this Oracle View and named one of the attributes as a primary key. I also added a entity object and view out of an oracle table.
I created a viewlink to display a master detail relationship. When I test the BC4J module I can see the master detail relationship, but when I want to create this master detail with the use of data tags (as the examples in How to Navigate Master and Detail JSP using data tags) I get the error RowkeyValue is Null.
If I am using the original table as a master which has a primary key everything works.
I know that Oracle also reference the Primary Key to a RowID.
Is there any solution to use an Oracle View without a reference to be used in a master- detail relationsship in JSP?
Thanks in advance

You might want to try generating a Complete master detail BC4J JSP application on your BC4J logic
which contains a view link.
Once the app is generated you'll see a working example of how to do a master detail BC4J JSP..
Basically the app will generate a JSP page for your viewlink..
Here's a real simple example of how to do a master detail BC4J JSPs where you pass the Rowkey as a parameter to a detail page which uses the JBO:Row tag to locate the Master dept record, which then drives
the detail record location..(since it is bound..)
This uses a default Emp and Dept tables. Also EmpView3 is a ViewObject which is bound via a link to
the master DeptView1 View Object.

How do I - MASTER -DETAIL JSP

Hi -
How do I create a simple Master-Detail page in JSP like Oracle Forms type.
I want to show/enter one master record and multiple child records and let the users enter data. I DO NOT WANT TO CREATE SEPERATE MASTER AND SEPERATE DETAIL JSP PAGE. I want the basic Master-Detail Form like Oracle Forms.
I am using JDeveloper 3.2
Thanks for your help !

In our current release, we dont generate a single-page master-detail editing page. You would are missing an editable data-grid tag for this to be possible. You can create this control yourself using the provided datatags.

Master/detail and problem with selected row when errors on detail row

I'm using JDeveloper 10.1.3.3
I have a very simple master/detail screen (JSF JSP) where master is departments and detail is employees in the selected department. Some of the attributes in employees are required.
To department A
I take away the value of one of the required attributes of one of the detail employee rows.
Select one of the other departments ie department B
Get Error message Value required.
So far so good, but the selected department is B and the detail rows shown is for department A.
I expected that department A to still be selected or that department B with its row to be shown.

Hi,
if (row != null)
Row masterRow = row;
vo.setCurrentRow(masterRow);
// not needed : getMesReponsesPourTiersVO1().executeQuery();
You shouldnot execute the child VO after setting current row in master VO.
When the current row is set in master VO, then the child rows will get refreshed automatically.

Master-Detail and Master-Detail2 forms, elementary approach, needed

For showing on one form 1 master and two details tables (all updatable)
On one form, MRU, MRD Data manipulation processes are not possible, so manual approach is needed (AFAIK).
How to implment this...where to read.
THX!

Well, I have serious doubt for long questions...so I try to short as possible.
I have Form Master detail created through Wizzard. I want to add another table which is also 1:m detail from the same master.
I have succesed making second report (based on query) but it is not updatable. Deletion is don in For update and insert I have use aother page.
I want some instructions how to implement this feature on one form regerding MRU is not possible to implement on one page for different tables.
Just 10 sentences how to make such a thing. It will be nice to hear that this and this is not good for that and that reson and the best way should be do in this way..
OK!?

Help needed to create a master-detail JSP page using OAF.

I like to create a master-detail JSP page using OAF. If any help or guide will be appreciate.
- Kausik

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.

Creating master detail rows

using adf/bc with jsf. I have defined a master detail relationship between two entities. This relationship is a composition relationship. The entities are related by a view link which link the master and detail view objects. i have a need to create/insert a master row and a detail row programmatically "on the fly" so that when the jsp renders, the user will see blank inputs for both the master and detail view objects. The problem is that the primary key of the master record is not known at creation time ( it will be entered by the user) and therefore the detail record cannot be created by the framework because of the unknown value of the parent's primary key. I was hoping the following section in the adf guide would eliminate my problem, but it doesn't appear to:
This is from section 26.7.3.2 of the adf developer's guide
Note: An alternative to the programmatic technique discussed
above, which solves the problem at the J2EE application layer, is the
use of deferrable constraints at the database layer. If you have control
over your database schema, consider defining (or altering) your
foreign key constraints to be DEFERRABLE INITIALLY DEFERRED.
This causes the database to defer checking the constraint until
transaction commit time. This allows the application to perform DML
operations in any order provided that by COMMIT time all appropriate
related rows have been saved and would alleviate the parent/child
ordering described above. However, you would still need to write the
code described in the following sections to cascade-update the foreign
key values if the parent’s primary key is assigned from a sequence.
This approach did not help in allowing me to create the detail record without first knowing the value of the parent's primary key record in a composition relationship. The only thing i've found to work is define the relationship as just an association, and not a composition. However, this is a true one to many (composition) relationship and i would like to take advantage of some of the features of the framework that are there when a relationship is defined as a composition relationship. Is there any way to do what i need to do with a composition relationship defined between these two entities? Thanks.

Hi,
I guess you need a "Cascading LOVs".
1) Create viewObject for country values list. Named VO1.
2) Create viewObject for state values list. Named VO2.
3) Create view criteria for (bind variable) VO2 which can restrict the result by country.
4) Create view accessor to get VO1.
5) Create view accessor to get VO2. Define the bind variable value which can provide country info dynamically. I guess it should be a Groovy expression.
6) Create country LOV on step 4) view accessor.
7) Create state LOV on step 5) view accessor.
Done
On the view layer, you may enable PPR between country and state attributes.

JSP, getting Master-Detail to work

JDeveloper 3.2.3
JSP, getting Master-Detail to work
- I've made a project with a master table Dept and a detail table Emp via the wizards. Automatically views for both are made.
- Secondly i created an association between Dept and Emp (based on the field Deptno), the association is exposed to both entities.
- I followed the Help example 'Creating Maser-Detail JSP Pages Using Data Web Beans'.
4 Data Web Beans are created with this example
* NavigationBar Master
* ViewCurrentRecord Master
* NavigationBar Detail
* RowSetBrowser Detail
The resulting JSP page shows, unfortunately, no link between the master and the details.
For one department all employees (of all departments) are shown.
What do i have to do to make the JSP Master-Detail work with JDeveloper
Thanx in advance

I resolve my problem to create a third level detail as viewobject as a own instance, without link to second level detail (as I supposed it to work). And manually make a new search with where clause inside working detail iterate loop (below).
I still wonder, is there any way to automatically update second details current row, which might also update third level details information as sophisticated way?
my solution to show third level in master-detail-detail information.
inside first details loop...
<jbo:ApplicationModule id="MyService" definition="DataBindings.MyServiceDataControl" releasemode="Stateless"/>
<%-- search criteria from detail --%>
<c:set var="whereLauseIn" value="MYKEY_ID = '${Row['secondId']}'" scope="page" />
<jbo:DataSource id="Lausu" appid="MyService" viewobject="ViewObjMyThirdDetailInst" whereclause="<%=pageContext.getAttribute(\"whereLauseIn\")%>" rangesize="-1"/>
<jbo:RowsetIterate datasource="Lausu" changecurrentrow="true">

<td >
<jbo:ShowValue datasource="Lausu" dataitem="Col1" ></jbo:ShowValue>

Master-Detail-Detail JSP/BC4J Sync Problem

Hi everybody,
im having a strange problem with my MDD schema in my custom BC4J/jsp page,
I went through all other topics in the forum but couldnt find any analogue to my specific problem,
Lets call schema as M->D1->D2
What I need to do is to navigate my cursor on D1 using a rowkey, the problem is when i use <jbo:ROW ... action="find"> using the rowkey sent by DataEditComponent, it seeks the first row in my data source(in sync with Master) instead of seeking the actual row.
FYI, the problem disappears when I omit the master ViewObject (normal master detail using D1->D2)
Any comments appreciated (ofcourse ASAP ;))

Hi,
you can use the column- or alias-name of the first query like:
<dataQuery>
<sqlStatement name="Q_MASTER">
<![CDATA[
select field1,field2 from master_table
where field3 = 'ABC'
]]>
</sqlStatement>
<sqlStatement name="Q_DETAIL">
<![CDATA[
select field4,field5 from detail_table
where field6 = :field2 (where field2 is a column of Q_Master)
]]>
</sqlStatement>
Pay attention that the column-names (aliases) are distinct
