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 - 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,

"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."

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.

Problems creating extension (View Object) in JDeveloper 9.0.3.5

Note: I originally posted this on the JDeveloper forum - but I was told to post it in this forum.
This is on Windows XP Pro SP2 with JDeveloper 9.0.3.5 - patch 6469392 (appropriate for 11.5.10.6).
I'm trying to create an extension for a view object for the Oracle Applications Framework. I've exported the appropriate MDS repo contents to my system using export. One of the first issues I've seen is the step where I import the the business components XML file (server.xml) and I get the following warning:
Warning: This Business Components Package was built with an earlier version of Oracle Business Components for Java. Unable to upgrade since it is readonly. oracle.apps.pos.isp.server
I've encountered these strange "readonly" errors all along the way. When I try to create the VO itself, I notice the wizard is in readonly mode, preventing me from associating query columns with view attributes (I cannot change a view attribute for a query column for many of the query columns). Why are things in readonly mode?

I've seen is the step where I import the the business components XML file (server.xml) and I get the following warning:
Warning: This Business Components Package was built with an earlier version of Oracle Business Components for Java. Unable to upgrade since it is readonly. oracle.apps.pos.isp.server
Ans : VO , EM and AM related xml files not need to import to MDS, only PG and Region related xml file need to import to MDS.

[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.

Error when opening view object in Jdeveloper

Hi,
EBS version is 11.5.10 RUP4. JDeveloper version is 9.0.3, Business Component Version is 9.0.3.13.93.
We need to modify a custom view object that has been extended from a standard VO. We do not have the original Java file of the custom VO, only its classes VOImpl and VORowImpl. As such, this should not be a problem: instead of modifying the custom VO we could extend it.
The problem:
When trying to update/extend the custom VO we get an error:
Copy operation failed, some edits may not be cancellable
Expected name instead of <.
Exception in oracle.xml.parser.v2.XMLParseException
Tracing back the problem we got this same error when OPENING the original VO. The original VO is oracle.apps.asn.opportunity.server.OpptySearchVO
Any idea how we can solve this problem?
Thanks in advance.
Regards,
Radu

Radu,
What kind of change you are trying to do, If you are try to change only the query without adding any parameter, you can open the VO.xml in a text file and change it.
One more way is, create a new VO substitution with the same name, and extend the VO, then Copy the VOImpl and VORowImpl code into your new files and use it.
What is the Jdeveloper Version 9.0.3 or 9.0.3.5
What is the Build version for the Jdeveloper.
Thanks.
With Regards,
Kali.

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
Edited by: user11922045 on Oct 19, 2010 2:53 PM

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.

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.

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
Srinivas

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 - 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.

ADF BC merge records of 2 view objects into third

jdev 11.1.1.4
Hi,
1) how to merge records of 2 view objects into third view object?
2) how to search inside view object whether the record already exists?
I want to do this in AMImpl programmatically.

hi I find that I can use something as below but it will check for each row at a time.
String exp = "student_id=" + "'" + studentId.getValue() + "'" + " and " +
"pass_word=" + "'" + password.getValue() + "'";
vo.setWhereClause(exp);
so if there are 10 records(to compare) i have to loop it 10 times(with company id and order id in exp) which i will be getting from some view.
and have to execute query 10 times so i don't think this is a efficient approach.

How to create ADF UI based on polymorphic view objects

Hi,
I'm using JDeveloper build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660. I created a simple application based on Steve's example #10 [url http://blogs.oracle.com/smuenchadf/examples/]ViewRow and EntityObject Polymorphism.
I added a men-only attribute "Age" to the "Men" VO and filled it with an arbitrary value in MenRowImpl.java:
public String getAge() {
return (String) "45";//getAttributeInternal(AGE);
}Running the TestModule works perfectly - a row of type "Men" displays the "Age" attribute whereas a row of type "Women" doesn't.
Afterwards, I setup an ADF ViewController Project and created a JSPX with a read-only form based on the "People" datacontrol with navigation buttons. Running that page always shows the same set of attributes independent of the row type. That's expected behaviour because the binding is defined at design time.
So my question is: can I somehow achieve the same behaviour for polymorphic VOs as the business component tester shows?
Kind regards,
Markus

Andrejus' example shows how to calculate different values for the same attribute based on overridden view objects. That's not exactly what I'm looking for. I need to display a (at least partly) different set of attributes that changes while the user scrolls through the records of the result set.
