ADF - Multple View Objects in one ADF table - Jdeveloper 11g

Hi,
I'm using Jdeveloper 11g, is there a way to use multiple view objects in one ADF table? And if so, do you have an example?
In my case the view objects are not based on a database table they were created based on an ESB wsdl, one is for person and one is for address.
Any information or pointers you could provide would be appreciated.
Thanks!

Hi,
That would be a good solution, however, I'm supposed to see if there is a way to use the VOs that were created for person and address. Even better if the solution requires little coding.
Is it possible to combine these two VOs into a single VO to use with an ADF table or to use both of them in a single table? Or is there some other solution that would enable me to use the person and address VOs in a similar manner?
Thanks!

Possible?Multi-Entity View Object with one Entity Object that is Read-only.

I know this sounds crazy, but I would like to create a multi-entity view object, where one entity object is based on a table in my application (we'll call it "Users", which basically stores the primary key for the person from the institutional people database), and the other table is a entity object based on a view of the institutional people database table (read only access), which we can call "People".
I know that since no updates will be done to the People table, it really should be a read-only View Object, but I would lose the ability to sort on attributes like Last Name, Hire date, etc, since those would be transient attributes in my ViewObject for the Users. By having People as an entity object, I can then create a multi entity view object and have the ability to join Users to People and be able to sort on the above mentioned fields (like Last Name).
The problem is that when I use the JDev (I'm currently using 10.1.2.1) AppModule BC4J tester, when I click on the multi-entity view object that I added to the AppModule it gives me an error:
oracle.jbo.RowCreateException) JBO-25017: Error while creating a new entity row for People.
----- LEVEL 1: DETAIL 0 -----
(java.lang.InstantiationException) null
I have tried to change all the attributes to updateable in my entity object, but no create method, and I have tried to make them all read-only, but no effect, I get the same error (probably because the People view is read-only in my schema).
Is there a way to change the entity object so that it will not try to create a new row when it runs the Tester? So that the multi entity view object behaves more like a view link, but gives me the added bonus of being able to sort on the Last Name column from the People table?
Thanks for any help on this subject...at worst, I will have to use the view link method to get the job accomplished, but it would be "cooler" if this would work!
Jeremy.

Steve, thanks for your quick response to my question.
To answer your questions, I was trying to create the Multi-entity View Object to give me more flexibility when working with my User table, and my People view. The flexibility I desired was that I would be able to sort my Users based on attributes in the People view. This is not possible when the there is only one Entity in my VO, and the People view data are all transient attributes, because they are not in the SQL statement.
Ultimately, after working with one of my colleagues, we decided to use the approach that you mentioned by creating a read-only VO with the SQL query we want to display to the user (contains both User and People data fields), and then use a different ViewObject when performing other actions on the User Table (such as inserts/updates/deletes). By using the setWhereClauseParam() method in the handleLifeCycle() for the JSP page, we should be able to navigate between the different View Objects, so that the user does not see any difference.
Thanks! Oh, and by the way, I have read your article you included before, and I have used it many times before to tune my View Objects! Thanks!

Bind a new view object to same adf table at run time

Hello,
I have an adf table, that changes based on the type of data the user selects. For example, lets say we have a page that consists of type drop down box at the top and an ADF table at the bottom, which lists data based on the type that is selected from the drop down box. For example, lets say, I have the types (Cars, Planes, and Trains).
Let's further say we have a view object for cars, one for Planes and one for Trains. Each VO has its own specific set of attributes associated with them, which in should be reflected in the adf table that's on the screen.
So for example, I select Train..
My table should contain the columns, num cabs, train type, year built
For plane, the columns might be Num engines, plane manufacturer, size(ie. 747, 727, etc), year built
Some type of thing with Cars , cylinders, color, model, year, etc.
Is there a way to tell my adf table to use a specific view object(ie. Plane, train, or car) at runtime?

You can try implementing this with dynamic components, e.g. dynamic table
>
ADF Dynamic and ADF Read-Only Dynamic Table: Allows you to create a
table when the attributes returned and displayed are determined dynamically
at runtime. This component is helpful when the attributes for the
corresponding object are not known until runtime, or you do not wish to
hardcode the column names in the JSF page. For more information about
working with dynamic components, see Section 26.7, "Using a Dynamic Form
to Determine Data to Display at Runtime."
>
Or you use dynamic regions and swithc the region containing the table depending on the selectOneChice. Check http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_regions.htm and https://blogs.oracle.com/shay/entry/adf_dynamic_regions_switching_just

Connecting ADF BC view object w/ param to a JSF Table?

I'm brand new to JDev so this is probably an easy one, I'm still trying to grasp some of the concepts: I have created an application module that has one view object containing a simple parameterized query (page is a simple search form - user enters keywords - I pass keywords to database and return results.) This Data Control shows up in the Data Control Palette and I am able to associate this with a table on the JSF page. Where I'm struggling is how / where do I tell JDev to bind the query parameter? In the examples from the help files, they show in the Data Control Palette a method with parameters. My Data Control Panel just shows the application module labeled as a Data Control with no parameters? In the Application Module (where I have defined the parameterized SQL stmt), in the Client Interface menu item, there are no methods available. Do I need to create the method even if I don't want to override the default functionality? Any help appreciated.
Also, many of the tutorial and examples look like they use the EJB/Toplink approach - are there good examples or tutorial for using ADF BC and ADF Faces?
Thanks. BTW - this product looks awesome so far! I was using myEclipse - this product is light years ahead.

This new 10.1.3-production JSF/ADFBC tutorial covers a lot of ground and includes an example of building the search page that you're trying to build, too :-)
http://otn.oracle.com/obe/obe1013jdev/masterdetail_adf_bc/master-detail_pagewith_adf_bc.htm
The trick is noticing that a View Object with named bind parameters includes an additional built-in operation in its "Operations" folder called ExecuteWithParams. Dropping this operation onto your page gives you the choice of creating a "Parameter Form" for your VO's bind variables. If you then drop the VO as a readonly table to the same page and run the page, you are done. :-)
Try to do that in Eclipse in two drag-drop operations! ;-)
It warms my heart to hear you say that about JDeveloper versus Eclipse... Really makes my day!

Using SQL view object to create ADF table

Hi,
I have created a column called "Month" (which extracts month from the date column) and another column to count the no. of requests.
i want to create an ADF table with 2 columns, a column showing the month and another is showing the no. of requests for that month.
However, now I only managed to achieve the ADF table to show the overall total requests, which means if i add up all the requests for all the months and i get 500
My ADF table shows this:
Jan: 500
Feb: 500
Mar: 500
How should I create the view or what should I do to make it such that the no. of request is based on the month?
Please advice.
Thanks (:

Hi,
For the given situation you can create a Query Based View Object with the following query
SELECT
COUNT(TEMP1.DT) REQUEST,
TO_CHAR(TEMP1.DT, 'Mon') MONTH
FROM
TEMP1
GROUP BY
TO_CHAR(TEMP1.DT, 'Mon')
where DT is the date column and temp1 is the name of the database table.
Following are the steps that i followed to get this query :
i have taken the following sample table :
create table temp1
(srno number primary key,
dt date)
*Note you may use any existing column instead of srno or use dt only (i took an extra column as u know we need a primary key /row id)
the following is the sample data
insert into temp1 values (1,sysdate);
insert into temp1 values (2,sysdate);
insert into temp1 values (3,add_months(sysdate,1));
insert into temp1 values (4,add_months(sysdate,1));
insert into temp1 values (5,add_months(sysdate,3));
insert into temp1 values (6,add_months(sysdate,5));
the table appears as follows
SRNO DT
1 22-JUN-12
2 22-JUN-12
3 22-JUL-12
4 22-JUL-12
5 22-SEP-12
6 22-NOV-12
To start with ADF View Object Creation (Using Jdeveloper 11.1.2):
Create the view object using Create View Object wizard
In Step 1. Name window
set the value for Name : Viewab (you can use any of ur choice)
In the data source section : select query
In Step 2. Query window
a. Click Query builder (it will pop up sql statment window)
b. In the SQL Statement window
in quick-pick objects section -> select temp1 table -> shuttle the columns from available list to selected list
in select clause section -> select srno column from select list-> choose count() function from function drop down list -> insert function -> set alias to REQUEST-> click validate
now select dt column from select list -> choose to_char() function -> click insert function -> alter the function to to_Char(temp1.DT,'Mon') -> set alias to Month -> click validate
in the group by clause section -> Click the green symbol to add -> from the expression palette insert dt column -> insert the to_char function -> alter the function to to_char(temp1.DT,'Mon') -> click validate
in the Entire SQL Query section -> click test query -> in the test query window -> click query result-> you will see the result -> click close -> click ok
Click next
Step 3: Bind Variables
Click Next
Step 4: Attribute Mappings
click Finish
So the view object is ready :)

ADF BC View Objects: Disappearing where clauses

Playing around with the 11g Technical Preview I find out that sometimes the where clauses - added to View Objects by means of the new "Join Type" field in the VO-editor UI - disappear.
I'm not able to reproduce exactly and "on demand", but it seems to happen when the sources of more than one View Object are open simultaneously and/or the XML definition of a View Object is edited directly on the Source-tab.

Today I succeeded in reproducing:
Two tables:
TAB_MASTER:
ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL:
ID NUMBER NOT NULL
MASTER_ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL.MASTER_ID is a foreign key referencing TAB_MASTER.ID.
Steps to reproduce:
1. Generate default ADF BC objects from database tables.
2. Open definition of TAB_DETAIL View Object.
3. Go to the Entity Objects tab
4. Add TAB_MASTER Entity Object to the Selected Entities Objects. Association and Join Type are filled in automatically.
5. Go to the Query tab and go to SQL tab in de Property Inspector. Where clause is filled.
6. Go to the Attributes tab and click Add from Entity...
7. Add TAB_MASTER.DESCRIPTION attribute.
8. Again, go to the Query tab and go to SQL tab in de Property Inspector. Where clause is still filled.
9. Go to the Attributes tab and select MASTER_ID attribute.
10. Click icon to add List Of Values
11. In List Of Values dialog add View Object TAB_MASTER and add the correct pairs of List Return Values for the ID and (MASTER) DESCRIPTION attributes.
12. After completing the List Of Values dialog go to the Query tab -> SQL tab again. The where clause added to join the Entity Objects (see step 5.) is cleared, resulting in a wrong SQL statement for the View Object.

[SOLVED] ADF BC : View Object "second level" Entity reference issue

hi
If I insert a row in a View Object that uses "two levels" of Entity references, the attributes of the Entity on the "second level" don't get a value.
Consider these tables:
MY_ROW (MY_ROW_ID, MY_ROW_STUFF, MY_ROW_LU1_ID)
MY_ROW_LU1 (MY_ROW_LU1_ID, MY_ROW_LU1_STUFF, MY_ROW_LU1_LU1_ID)
MY_ROW_LU1_LU1 (MY_ROW_LU1_LU1_ID, MY_ROW_LU1_LU1_STUFF)
Where MY_ROW.MY_ROW_LU1_ID is a "look-up" in MY_ROW_LU1 and MY_ROW_LU1.MY_ROW_LU1_LU1_ID is a "second level look-up" in MY_ROW_LU1_LU1.
I created default Entities and Associations on these tables and a View Object that uses all 3 Entities (MyRow as Updatable, MyRowLu1 and MyRowLu1Lu1 as Reference).
See example code in
http://verveja.footsteps.be/~verveja/files/oracle/ViewObjectEntityReferenceIssue-v0.03.zip
(contains no Java code, all out-of-the-box ADF BC)
problem scenario:
If run the MyRowService Application Module in the Oracle Business Component Browser and "open" the MyRowViewAll View Object instance, I get the rows and their related "look-up values".
If I click the "Insert a new record" button and fill out values for MyRowId, MyRowStuf and MyRowLu1IdEntity, I only get "look-up" values for the "first level". While the "second level" stays empty.
For example, a MyRowLu1IdEntity of "2003" gives a MyRowLu1Stuff value of "2003 stuff", but no value in MyRowLu1Lu1Stuff.
What am I doing wrong? What should I change to also get a value in the "second level" MyRowLu1Lu1Stuff attribute?
many thanks
Jan Vervecken

Jan,
If you create a view object on Emp and Dept, with Dept as a reference entity, you might choose to build the view object to only include the:
Emp.Empno (required, since it's the PK of Emp entity usage)
Emp.Ename (included since you want to show the ename)
Dept.Deptno (required, since it's the PK of the Dept entity usage)
Dept.Dname (included since you want to show the dname)
The wizard enforces the inclusion of the required attributes above.
When you run this view object, a join is performed and you see the reference data.
Now, if you want to allow the user to UPDATE the reference data, you need to add one more attribute to the list of attributes:
Emp.Empno
Emp.Ename
Emp.Deptno (To allow user to change Deptno employee belongs to)Dept.Deptno
Dept.Dname
At this point, not only is the join performed for you, but the ADF BC reference mechanism reacts to any modification of the Emp.Deptno attribute, correctly showing the reference information for that new foreign-key-referenced department (even before commiting and requerying, at which time the SQL join would pickup that correct, related information).
The "second level" problem you describe in this thread is simply the same issue described here as a master/first-level-detail situation, taken to its logical next step. If you want the end-user to be able to change the second-level detail to which the first-level-detail is associated, you need to include the first-level-detail's foreign key attributes in the view object's select list. Otherwise, there is no foreign key attribute whose value-change event the framework can react to in order to coordinate the related reference data in the row.
I've blogged a link to a working example of a four-level reference information view object here:
http://radio.weblogs.com/0118231/2007/05/09.html#a818
based on the HR schema.

ADF Join View Object

we have a Join View Object joining Customer and Order tables. The Output in ADF table is like this
CustomerName------------OrderID
John------------------------------------1
John------------------------------------2
John------------------------------------3
Tom------------------------------------80
Tom------------------------------------81
Tom------------------------------------82
We need to show the out but as
CustomerName------------OrdersPlaced
John------------------------------------1,2,3
Tom------------------------------------81,82,83
Please suggest how we can acheive this
Thanks

Our requirement is similar to a Order - OrderDetail example, (where the number of details many times wont exceed 3)
The Order table has just the Order number and some name... and Order detail has order item, price and date detail item requested ..
So we just need to show the list of Order and for each order( the details..item no, item, price, date time req)..
As you can see we can fetch it in one single query..
I can't ask the user to click on the Order number/name to see the Order details in adifferent table every time.
Typically when i was using java.. i used to populate the details into the Order VO as an ArrayList of Order Items. w could delete just one detail/ as well as a complete Order all together.
Please suggest.

How to change the default behaviour of View Object in oracle adf

Hi,
I have created a view object from an entity object and placed it as a table with multiple lines on my page.
When I run my page, by default, it loads all the rows based on the sql in the VO.
My requirement is when I load my page, I don't want to return any data in that table.
I am using JDeveloper 11.1.2.4.
Please can you advise how can I achieve this functionality?
thanks
Muhammad

Performance Issues due to Loading of ADF/JClient View Objects

Hi,
I developed a two-tier ADF/JClient application.
When the ADF/JClient application opens for the first time, there's a big delay
However opening it subsequently, takes less than half of the time to open the screen.
I think it might the xml files of different view objects which the framework loads for the first time, and thus takes a lot of time. And after that, the time to open the application reduces.
We have around 200 view objects in our application. Can this be the reason?
If yes, then can we load the view objects before ahead, or can we just load them at the very time they are requested ?
Thanks,
Makrand Pare

Hi Makrand,
Check this out:
"Limiting Fetching of Business Components Attributes in ADF Swing
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtTopicFile.developing_jclient_applications%7Cjui_plimitingfetching%7Ehtml/
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute properties is not supported.
You can optimize startup time for a Business Components client application and the remotely deployed Business Components by specifying the list of view object attributes that your client uses. If you create a project without the metadata, by coding to the API, you will want to add fetchAttributeProperties() to the bootstrap code of the client forms with a list of only the attributes used by the form. Without this method call, your client form would fetch all control hint properties (including the attributes format and label for example) for all the attributes of the named view objects in the application module, in a single network roundtrip.
For example, when you do not intend to use all the attributes of the ADF Swing form's bound view object, with the fetchAttributeProperties() method, your ADF Swing form fetches only the information required to layout your forms, while ignoring the attributes you do not require.
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute pro
Calling fetchAttributeProperties() will prevent property methods such as getFormat() or getLabel() from being called on the Business Components attribute definition whenever the form is created."

Programmatically populate ADF BC view object based on user's JAZN roles

I currently have a ADF BC read-only view object that is based on an sql query.
I would like to assign values to the bind variables based upon the user's JAZN
roles. My problem is that I am uncertain how to obtain the roles the user has.
Any help would be appreciated.
Thanks,
Kenrick

I do believe this topic is discussed in detail in the 4GL Developer's Guide. Section 30.8 describes everything how to obtain user info programatically. Aside from pointing you in a direction that will get you where you need to be, I can't be of much help. I'll be crossing that hurdle in the coming months.
Download the guide from this page:
http://www.oracle.com/technology/documentation/jdev/b25947_01/index.html. I printed and bound it and use it as my bible.
Good Luck,
Jeff

Thanks for your time

Thanks frank i will do that , as a work around , the error is resolved by changing the query from select order# , other fields to select order# as ordernumber etc

ADF : Merging View Objects in JDeveloper

There is a view object called ProjectVO, under this view object I have ProjectApplicationVO(Hierarchy In Data Controls). So using PPR Ican get project Applications related to each project.
But there is a another viewObject ApplicationVO which has ApplicationDocumentVO (Hierarchy In Data Controls)in it.So I can get documents related to each Applications using PPR easily.
Now I have a new requirement..... Which is ,
If I click on a project from ProjectVO, I should get ProjectApplications related to that project which I can do using hierarchy present in Data Controls. But after this if user clicks on any application from ProjectApplicationsVO, I need to display documents related to that Project Application.
Could anyone please let me know how to implement it?
Existing ViewObjects:
ProjectVO---->ProjectApplicationsVO
DocumentVO---->ApplicationDocumentVO
Requirement:
Project----> ProjectApplications----->Application Documents

Uix two view-objects on one entity-object synchronize

Hi All
I want to add some uix pages to an old project using ADF UIX and Business Components.
I have an entity object to a table witch about 50 fields.
Now I create two view objects due to a better performance. One witch seven attributes for the overwiew and one with all attributes for the detail page.
They are related via a view link.
I create the overview as a read-only-table and the detail-page as an input-form.
The proplem is that the synchronization don't work. The detail page shows the first dataset ever.
Has anyone a solution or a tip where I can found that?
Is where a performance problem if I use one view-object for both pages?
Thanks in advance
Roger

Use custom DataAction for the first page:
package controller;
import oracle.adf.controller.struts.actions.DataAction;
import oracle.adf.controller.struts.actions.DataActionContext;
public class Class1 extends DataAction
protected void validateModelUpdates(DataActionContext actionContext)
//super.validateModelUpdates(actionContext);
// put you custom validation here

Multiple ADF Business Components projects for one ADF project

I have an ADF project where I have my own ADF Business Components Model, with View Objects, etc. Can I add another ADF Business Components from another project - they access a different database than I do with queries that I could use.

I see two options:
1. rename one of your Model.jpr to somthing else and then try again to add a dependency.
2. create a jar out of the second model project and import the applcation module out of the jar into the other project. To import use file->import and select 'Business Components' from the list. Check tho docs ("Importing Business Components Created by Someone Else")
