ViewLink between DB and Programmatic View Objects

Im using programmatic view objects as described in #132 of http://blogs.oracle.com/smuenchadf/resource/examples
I can create view links between these programmatic view objects, but when I create a ViewLink from a DB ViewObject to a programmatic view object, the programmatic one fails to see the view link when invoked, and therefore doesnt return the correct detail objects.
Has anyone created a view link like this before? If so, can I see the code or an example?

If you look at example #132 above, you'll see a ListOfMapsDataProviderViewObjectImpl - which is a custom ViewObject that delivers data programmatically. There's a method in this object "getFilterCriteria(..)" that looks at the parameters delivered to the ViewObject, and any ViewLinks, to produce a map of parameters that the underlying DataProvider can use to filter its data. When you setup a ViewLink between two of these ViewObjects you may see a filter on a foreign key, since the master view object is retrieving its detail objects. However, when the master object is a standard database view object, the view link doesnt work, i.e. the getFilterCriteria method does not see the view link when it calls ViewObjectImpl.getViewLinks().

Diff between get and find View Object methods.

Dear Forum,
I have a very basic query to ask as a newbie. In oaf examples and dev guide I see usage of get<voname> and am.findViewObjects('<vo name'>);
what is the difference between 2 calls and when to use each and where. An example to use each in relevant context would be great !
Thank You
Shanky

Shanky,
You can any one of the method but calling get*VO is always fast compare to find*VO because find VO will iterate through all the added method inside the AM and then use the get*VO method.
Mostly we use get*VO from the AM whereas findVO is mostly used in CO.

Programmatic View Objects + View Links

Ive constructed some programmatic view objects to grab data from 2 custom java business services (for example: Persons and Addresses). The reasons for them being custom and separate are out of my control.
I need to easily represent a relationship between these 2 view objects so Ive constructed a ViewLink between them. However I cant figure out exactly what ADF needs from me in terms of method implementations in my ViewObjects?
When I drop the master data control onto a JSF via a Tree table, it looks as though its not actually filtering the detail rows. I.e. if master is a Person, and detail objects are Addresses, each Person tree node has all Addresses under it. Im assuming this is because the Address ViewObject is programmatic and so ADF doesn't know how to filter the results?
How can I setup this ViewLink between 2 programmatic ViewObjects such that the ViewLink works like its supposed to?

Hello,

View Links for Programmatic View Objects

Hi All,
I created a read only VO called MyVO based on a sql query.
I created 2 programmatic view objects, MasterView and ChildView.
In a custom method in AMImpl class ,I iterate through this MyVO resultset and get the rows in a Row object.
Based on some attributes values of the Row, I populate both master and child View Objects.
I have created a view link between Master and Child Programmatic View Objects and have exposed them in AM.
Now I run the AM, and run the method exposed in client interface.
Now I click on my master and child programmatic views.
I see that the rows are populated in both of these programmatic VOs.
But when I click on viewlink which I have exposed under master, it doesnt show me any
record for child.
This is my method of AMImpl which is exposed in AM client interface.
public void constructLines(){
ViewObject vo= this.getMyVO1();
ViewObject master=this.getTransientVO1();
ViewObject child=this.getTransientLineVO1();
Row r,masterRow,childRow;
int count=0;
while(vo.hasNext()){
++count;
r=vo.next();
masterRow = master.createRow();
if(r.getAttribute("QuoteHeaderId")!=null)
masterRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
if(r.getAttribute("QuoteLineId")!=null)
masterRow.setAttribute("QuoteLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("LineNumber")!=null)
masterRow.setAttribute("LineNumber",
r.getAttribute("LineNumber").toString());
master.insertRow(masterRow);
childRow= child.createRow();
if(r.getAttribute("RefLineId")!=null)
childRow.setAttribute("RefLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("QuoteHeaderId")!=null)
childRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
child.insertRow(childRow);
This is stopping me from my development progress.
Any suggestion to solve this will be of great help.
Thanks,
Prabhanjan

Hi..
have you define relationship correctly between masterVO and childVO.sometime there may be the problem.

This almost works except when I try to print out the attributes I get an error. I beleive I have to override some of the view object framework methods. If so, how do I go about this? Is it the same methods overridden in this example Getting a View Object's Result Rows from a REF CURSOR? http://radio.weblogs.com/0118231/stories/2003/03/03/gettingAViewObjectsResultRowsFromARefCursor.html

Yes. only difference is that your VO will just have one row in it.

View Link on two programmatic view objects

Hello,
I use Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407
I have two programmatic View Objects with data from other sources (an ArrayList in my example).
Now I would like to create a View Link on it. How can I do this?
I'm quite new on Java and ADF...
I know it is possible because I already found Steve's example 132 here [http://blogs.oracle.com/smuenchadf/examples/|http://blogs.oracle.com/smuenchadf/examples/]
But could somebody create a simple example based on my example classes below (which is understandable for a newbie like me ;-) ?
Has been asked already here, but I did not found a solution as yet.

Thnx in advance!

Rolf,
I guess when we try to do it for you, we end up with almost the sample code provided by Steve Muench.
So there from my point of view it doesn't make sense to do it all over.
Take some time and study the sample code, run it without changes and after that try some changes which suits your use case better.
If you don't understand what's going on in the sample post the question here and we try to help you.

Changing a Programmatic View Object's query at run-time

Hi,
I've created a programmatic View Object using the information in '35.9.3 Key Framework Methods to Override for Programmatic View Objects' in the Oracle Middleware Fusion Guide and bound it to a BarChart. This has worked fine using the following:
String myColumn = "Quant1";
protected void create() {
getViewDef().setQuery(null);
getViewDef().setSelectClause(null);
setQuery(null);
String myQuery = "SELECT Service as MyService, " + myColumn + " as MyValue FROM ColumnTestTable WHERE 1 = 1";
getViewDef().setQuery(myQuery);
setQuery(myQuery);
I also have my data updating automatically. I have public properties in my viewObjImpl class which I can set and update the value of myColumn. I then thought it would just be a case of re-calling the create() method and the SQL would be updated and my chart would auto-update using the new column to select it's values, the value of the property updates and the create method is called but the chart doesn't display any different data and stops auto-updating. Does anybody know if this is possible and if so what I may have missed?
Cheers, Tom

Hi Timo,
I moved everything to a different public method and solved the problem by firing the execute() method which I hadn't been doing previously and the chart updates with the correct data.
However, once I execute the SQL my chart stops auto-updating with changes to the data in the database - do you know how I update the SQL query but keep my chart auto-updating? Perhaps I have to re-register for the registerDatabaseChangeListener for the query collection?
Thanks in advance, Tom

Issue in programmatic view object.

Hi,
I am creating a programmatic view object, in a button's action listener. I have used ViewObject.clearcache() to flush the VO previous data, every time the button is clicked and load new data. The issue which i face, is that the table showing the VO data, shows data in alternate attempts i.e. 1st,3rd and 5th button click and in the 2nd, 4th click it shows "No data to display." . If i try using ViewObject.reset() the table is loaded with data every time but the new result set gets appended, which gives duplicate data.
Please help.

Max

What is the diffrence between extends and creating new object?

HI ALL,
what is the diffrence between extends and creating new object?
meaning
class base{
class derived extends base{
class base{
class derived {
derived(){
base var = new base();
can u people tell me diffence from the above examples.
THANKS.
ANANDA

When you create a new object you have to supply the class to which that
object belongs. A class can extend from another class. If it does so
explicitly you can define the 'parent' class from which the class extends.
If you don't explicitly mention anything, the class will implicitly extend
from the absolute base class named 'Object'.
Your example is a bit convoluted: when you create a Derived object,
its constructor creates another object, i.e. an object from the class from
which the Derived class extends.
Extending from a class and creating an object don't have much in common.
kind regards,
Jos

Creating and Binding View Objects dynamically : Oracle Jdeveloper 11g

Hello,
We are trying to create and bind view objects dynamically to adf data visualization components.
The view object is a result of multiple tables.
We are using Oracle JDeveloper 11g Technical Preview. ( can't upgrade to TP2 or TP3 now).
We have found this : http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html on our search for the same.
The sample application however, is in 10g , hence required migration.
Also, it was a standalone application with the TestClient.java having a main() method.
Our requirement is for Web Application; we use Adf+jsf .
Guidance of any sort is very much appreciated.
Thanks in advance.
-Anil Golla

Hi,
there also exist a forum for JDeveloper 11: JDeveloper and OC4J 11g Technology Preview
What you are trying todo is not trivial because you need to not only dynamically create the VO, you would also dynamically need to create the binding meta data for it (assuming you use ADF). Not sure if the API to modify the binding is public, so posting it on the JDeveloper 11 forum bears a glimpse of hope for an answer
In JDeveloper 10.1.3 you can't do this

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Kumar

Dreamweaver Momentarily Freezing When Moving Between Code and Design View

I have Dreamweaver CS4 and have had a problem that just started yesterday. I have rebooted my machine to no avail. The local copy and the live copy of the site are on two different servers that we access through a local network.
Dreamweaver slows to a standstill if I click to another program and then attempt to go back into Dreamweaver or if I switch between design and code view.
I haven't made any changes to Dreamweaver in the way of added extensions or updates. Is it possible that the cause of this could be either a server problem or a connectivity to the server problem?
Many thanks in advance for any help you could provide.
Andy

Iterating through master view objects and child view objects in same page

I am working on a project using ADF UIX and Business Components.
I have an application module with two view objects one the master view object and the second the detail object. They are related via a view link.
I would like to iterate through the master view objects displaying a customer name as bold text and then below each customer name I'd like to display the detail records in a table via the detail view object i.e. a seprate table for each customer.
Is this possible - I haven't had much luck!?
Thanks in advance.

That's because
$(".ms-vb2 a").
is bringing back all the pieces that have that class with an anchor on the whole page, not just the ones in the .ms-wpContentDivSpace
I don't know the exact syntax, but I think you need to iterate through all the '.ms_vb2 a' items as well - there are multiple ones, and do something like this inside your other grouping
$(".ms-vb2 a").each(function(index) {
    var val=$(this).html();
   var val2=val.replace(/_/g," ")
   $(this).html(val2);
That's not quite right but maybe that will help.
