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.

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 - 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!

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!

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

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:

I Have a table with columns containing # character , for example ORDER# , When i create the read only view object j developer automatically renames this to order, but when i try to sort on that column or try search (filter) i get error that column order is not found
what i can change to resolve this
Thanks for your time

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

Hi,
I have created the View Link but I am not able to add this view link as a 3rd hierarchical in AM...
Can you please tell me how to add this View Link as a third hierarchy in the Application Module?

ADF - Accessing view object from a button in a window

Hi
I am using Jdeveloper 10.1.3.2.0 to build a Swing/ADF application.
I added a method to a view class to call a database procedure.
I use that view as a base of a jTable to display data in a window.
Now I need to call the method that I created in the view class from a button on the same window where I display the data, ideally using the same db connection.
I am quite new to ADF and I have no idea how to get a reference to the view instance in the button method to call my new method. How can I do that? Is there another way to achieve this?
Thanks!
Luis

You usually do this by creating the method at the application module level and then exposing it as a client method. You can then drag and drop it onto your form as a button.
See details in the ADF Developer Guide chapters 8.3-8.5:

Problem in ADF Tree When I use 2 Tree in a Page with same View Object !

Hi everybody,
I use JDeveloper 11.1.1.5 and ADF Faces in UI . I have 2 tree in a page that they are from same Updatable View Object but diffrent instances in application module . When I change an attribute value from one of them in manage Bean programmatically , both of them change??!! in my case I put a checkbox in nodeStamp, when user click on checkbox, title of row must change but title in both of them change?????
I think it is a bug.
please help me. Thanks

>
so what is diffrent to use same view object instances in page or multiple instances when we need ??
>
Actually, this depends on your use case. suppose you have a view object with a bind variable, and you want to display to tables on the same page but with different query result depending on the bind variable, in this case you have to create two view instances.

Problem with using multiple Entity Objects in a view Object.

Hi
Thank you for reading my post
I have create 3 Business components for 3 of my database tables and now
I must add 3 tables in a View object so i used Jdeveloper Wizard to create the View Object.
-I Add Entity Objects which are business components to this view (In Step 2 of the Create Vview Object wizard).
-In step 3 that I add Attributes all my attributes are marked as Transient
Can some one explain why it happens?
I need one of those tables to be updateable and two other tables are not updateable.
What should should i do to achieve this?
I should say that tables does not have any database relation (Foreign Key I Mean).
Thanks.

Hi user505214
When you created your VO, on selecting the second EO, you'll note at the bottom of the same page on the wizard/editor, checkboxes for updatable or by reference. By default reference is checked and this will make your second EO's attributes transient.
In the JDeveloper Developer's Guide for 4GL/Forms programmers, the following sections outline the difference between updatable or by reference:
7.5 Including Reference Entities in Join View Objects
27.9 Creating a View Object with Multiple Updatable Entities
Make sure to read 27.9 if updatable is what you want as it indicates you may need to add some additional code.
Hope this helps.

View object that will allow to see data from two tables in a adf table

Hi,
I've been have serious issues to resolve this functional requirements with ADF.
Basically I have two tables let say employee and department.
A need a read only adf table to show the employees values but I don't want the users to see the department id, instead I want them to see the department name and all this in the same read only adf table.
I created a view object based on such a query below:
select employeelastname, employeefirstname, departmentname from employee, department where employee.departmentid = department.departmentid (+)
Note the outer join here because some employees don't have department assigned but I still want to see them in my read only table.
The problem is that the view object is based on a sql query and is using calculated attributes instead of entities and I am getting that error "rowkey does not have any primary key attributes" each time I select a row inmy adf read only table. So the popup I defined when the user select a row does not work properly and I need a better solution. I will also have the option for the users to delete a record selected in the read only table so really need entities behind there not just a view.
My view object also include LOVs but I realized LOVs only work for tables but not for read only tables. Too bad the fonctionality is almost there... So even if I have lovs defined that show the data like I would like it to be seen for tables it does not help for ready only tables. Any way to have read only table working with LOVs (user will not be able to change the values or select another value in the list but at list they would see the department name instead of the department id)?
Thanks to anyone that would be able to help me on this.
Stephane

Let me first say that I would use Shays approach and only under special circumstances (which are beyond this thread) use the solution outlined below:
You can use the read only VO based on your query without basing it an entities. All you have to do is to mark one or more attributes as primary key in the VO. This should solve the "rowkey does not have any primary key attributes" error.
Now to delete a row (I'm not sure which row department or employee you mean here) you use the selected read only row, get the PK of the row and call a service method in the application module of in a VO which is based on an entity and remove the row there. You can even use the removeRowWithKey operation from the data control to archive this.
The second problem I don't understand. If you show the user a read only table there in no need to show a lov as you can't change the value. If your problem is that you need to show the department name instead of the department id, you simply add the department name to the attributes you select with your query.

ADF table and ADF form on the same view object

Hi,
As per the ADF demos available on ADF site, I created a jsf page with 2 panels. One panel is an ADF table based on a view object. And the other panel is and ADF form based on the same view object. My requirement is that as I scroll through the records in the ADF table, the ADF Form should dynamically display the details of the record in the ADF table. My understanding is that this should be automatic. However, its not working as expected. What have I missed?

Hi,
Apply PPR for form that displays details.
Like :
<af:table id="t3">
</af:table>
<af:panelFormLayout id="pfl2" partialTriggers="t3">
</af:panelFormLayout >
