Questions on creating second RowSetIterator on View Object
I am using JDeveloper 11.1.1.4.
I created a second RowSetIterator for my view object so that I could perform some logic on all rows of the view object without affecting its currency.
I called the createRowSetIterator() of the view object to create the second iterator with a hard-coded name "temp".
When my logic was called the second time, will there be any problem to create the iterator with the name "temp"?
I expected the iterator would be treated as a local variable which would become eligible for gargage collection once exiting my method.
Is this assumption correct?
Otherwise, what ViewObjectImpl method can be used to remove the iterator?
If you don't need the iterator any more, you should close it
RowSetIterator rsi = vo.createRowSetIterator("Listenauasgabe");
rsi.closeRowSetIterator();As far as I understand the docu your assumption is correct as long as you don't have something else pointing to the iterator.

ADF -how to create table binding when view object is no known until runtime
I want to programmatically create a table binding to a view object where the view object name is not known until run-time. Then I will use a dynamic table to display it. Can anyone provide an example?
I looked at example #9. It gets me closer to what I am looking for but not quite enough. In my case, I don't have (or want in this case) a pageDefinition with a pre-declared Iterator binding. I am converting an exsisting BC4J/Struts/JSP application. I would like to rewrite my reusable component tags to make use of ADF bindings and Faces. My tags are passed the ApplicationModule and ViewObject names as parameters, much like the old BC4J datatags. I do not want to go back and rewrite all of my pages from scratch using drag-and-drop declarative bindings with a pageDefinition for every page. I am hoping to have my rewritten tags handle everything programmatically based only on the ViewObject name passed at run-time.

Creating emty rows in View Object
Hi,
My Application is ADFBC.
My requirement is create empty rows while page loading.I am using three tables one is master and another two are detailed tables.
creation form is: master form
detailed table
detailed table.
when i am pressing create button the form shows two emty rows in detailed table and 7 empty rows in second detailed table.
i wrote code in AMImpl is
public void createcomp() {
SequenceImpl s = new SequenceImpl("ATTRIBUTE_ID_S", getDBTransaction());
Number next = s.getSequenceNumber();
Number n=(Number)s.getData();
Number ssid=next+(new Number(1));
FbCmnEmcStorageSystemsVOImpl fbCmnEmcStorageSystemsVO = (FbCmnEmcStorageSystemsVOImpl) this.getFbCmnEmcStorageSystemsVO1();

fbCmnEmcStorageComponentsVORow.setStorageSystemId(new Number(ssid));
fbCmnEmcStorageComponentsVORow.setComponentName("sample"+i);
i am calling this method while page loading using these procedure:
expose the method as a client method and create a method binding for it (in pageDef). Then create an invokeAction (also pageDef but Executables section) pointing to the method binding. Set the invokeAction refresh condition (property of it) to
${!adfFacesContext.postback}
but i am not getting emtyrows in display.
what i have to do?please help me.

JDEV 10.1.3: Using "Create" binding on BC view object with ADF Faces Table
Hello,
I am trying to get this to work, but to no avail:
I've got a very simple page (ADF Faces - JSPX) created by dragging an iterator from the data control pallete on to my page and picking "ADF Table..." as my chose to create. This creates a table on my page that allows me to edit each row in place. Very nice.
Now, I dragged the create operation for that iterator on to the page. What I had hoped to see is that when I click "Create," a new blank row appears in my table (well, at least a row that is blank except for any default values specified in the EO/VO and my overriden create() method).
However, this doesn't happen. The page submits and refreshes, but no blank row shows up. I initially tried setting the Create button to do partial submit and setting the partialtriggers for the table to include the Create button, to no avail. I also tried it without the partial submit with the same results.
So:
1). Should this work, or is this behavior a bug.?
2). If not, is there a different/better way of doing it?
Regards,
JohnG'day John
I think I can give you a hint of what is occuring... I'm still trying to work out what is happening exactly.
In JDev 10.1.2 UIX, when the user invoked the create action, they would see the blank record added to the underlying table. Under 10.1.3 Faces the functionality is somewhat different.
When you the user clicks on the create action a blank record is created but not shown in the table control. To prove the blank record is there try this:
1) Build an ADF Input Form based on the same VO iterator
2) In your JSF navigation, create a navigation case between the existing page and the new page, and another back again,
3) In the existing page, map the Create button's action attribute to navigate to the ADF Input Form
4) In the ADF Input Form, map the Submit button's action attribute to navigate to the ADF Table page.
Now when you run your app, notice when you create a new record in the ADF Table which automatically takes you to the ADF Input Form, note the blank record, and the details you enter into the record here and submit, are then visible in the ADF Table on the return.
This is a long way of proving that the new record is in the table. It's just you can't see it.
I have a theory which I'm trawling through the newly updated documentation to verify. This issues goes back to the VO createRow vs insertRow method calls that have been documented by Steve Muench a couple of times. I'm guessing the table control is now smarter and doesn't show createRow records, only insertRow records.
Read one of Steve's posts here regards the createRow vs insertRow method calls:
http://www.oracle.com/technology/products/jdev/tips/muench/blankrow/index.html
If I find anymore info I'll endeavour to post it.
Meanwhile this of course doesn't help you if you actually want to show the blank row in the ADF Table editable control, but I'd thought I'd give you an idea of what's happening behind the scenes.
Hope this helps.

Possible bug when creating multiple detail view objects
using jdev 11.1.1.0.0 to build jsf/adf applications. I wanted to report what seems like a bug in 11g. I have a parent table which has two child tables. After creating the appropriate entities, associations, views, and view links, the app module looks like this:
MasterView
--DetailView1
--DetailView2
The two detail view objects are on the same level, they are both direct children of the Master view.
Here's what's happening:
1) I create the master entity/view objects (MasterView)
2) I create one of the detail entity/view objects (DetailView1).
3) I create the association and view link to establish relationship between MasterView and DetailView1. Everything works fine.
4) I create the entity/view objects for second detail view (DetailView2)
5) When I attempt to create a second view link (based off an association) to establish the relationship between MasterView and DetailView2, the query clauses of the Create View Link wizard (screens 4 and 5) do not get created properly. I finish the wizard and save. Not only does this view link not get created properly, but in the process the query clauses that were defined in the first view link between MasterView and DetailView1 are wiped out. This will break any coordination between master and detail views in both the app module tester and runtime. Has anyone seen this problem?fyi, it looks like this issue has been resolved with jdev 11.1.1.0.2 (Update 2)

How to create dynamic View Object and Dynamic Table
Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
public void changeVoQuery(String dbViewName) {
String sqlstm = "Select * From " + dbViewName;
ViewObject dynamicVo = this.findViewObject("DynamicVo");
if (dynamicVo != null) {
dynamicVo.remove();
dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source

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 :) -
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! -
Getting data from view object into backing bean
Hi,
My requirement is explained below -
I have a ADF editable table in a jsf page which is connected to backend database table. In the table there are 6 columns and only 2 are editable. So when user inputs a value in first input column an event is triggered such that the data for all the remaining columns should be fetched from another database table.
Typically if we are not using ADF development environment. We would have had a simple business method which creates the sql query by taking the input from textbox with simple where clause and I would have got the data. I am not getting any idea how to do this in ADF. I have the second table as view object but how to access the view object from backing bean and get data based on the input given.Hi,
step 1) Expose a method on the ViewObject Impl class
step 2) define arguments for the method as needed to identify the row to read data from
step 3) retrieve the row from the VO that holds the data you want to add and return a HashMap with this information
step 4) expose the method on the client interface (Java menu selection on the View Object)
step 5) In the PageDef file, create a method binding to the method you exposed on the ViewObjectImpl
step 6) Call the method binding from the managed bean like
OperationBinding getDataFromVO = (OperationBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("Name of method binding);
getDataFromVO.getParamsMap().put("name of arguments1", value1);
getDataFromVO.getParamsMap().put("name of arguments2", value2);
Object retData = getDataFromVO.execute();
if(retData != null && getDataFromVO.getErrors().size()==0){
HashMap retDataMap = (HashMap) retData;
... follow the rest of your logic ....

Issues in persisting dynamic entity and view objects using MDS

I'm trying to create dynamic entity and view objects per user session and to persist these objects throughout the session, I'm trying to use MDS configurations(either file or Database) in adf-config.xml.
I'm facing following two errors while trying to run the app module:

I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

How to retrieve the values from a Transient View Object
Hi Experts,
I am using Jdevelpoer11.1.1.5.0. I created one Transient view object with attributes EmpId,Salary.
In Backing Bean i will create rows for that view object and display it in the form of <af:Table> like Empid, Salary and an Update Link.
Now my problem is i want to update the salary of the particular EmpId. For Example if the EmpId is 100 and salary is 10000 now i want to increase the salary to 20000 and if i click on the update button; i want to retrieve the particular employee details in my backing bean. How can i acheive this?
Thanks in advance.A better approach would be to programmatically populate rows in the <VO>Impl.java by overriding the executeQueryForCollection(0 as specified here -
http://adfpractice-fedor.blogspot.in/2011/01/adf-bc-programmatically-populated-vo.html
You can write the logic to update the salary in an AM method then on click of Update or in the getter of Salry field if logic is valid for all fields... -
ADF BC: range paging on dynamic view object
hi!
i have a dynamically generated sql query and i want to get the results one page at a time. for this to work i create at runtime a view object and try to use range paging:
String sql = "SELECT ...";
ViewObject vo = appModule.createViewObjectFromQueryStmt("tmpVO"+System.currentTimeMillis(), sql);
vo.setRangeSize(pageSize);
vo.setAccessMode(RowSet.RANGE_PAGING);
vo.scrollToRangePage(pageNo);
vo.getEstimatedRowCount();
Row[] rows = vo.getAllRowsInRange();
vo.remove();
but when i run this it was pretty slow. so i traced the database session and saw that the executed query was the sql string, not the range paging select (SELECT * FROM (SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (...).
i use range paging on other view objects that are not dynamically generated and it works fine. please tell me what can i do to get only the specified page from the data base.
thank you
Edited:
here is the select i run:
SELECT UnitEO.UNIT_TYPE, UnitEO.UNIT_NR,

PS: I am using JDev 10.1.3.36.73You have a couple of choices. You could create one view object with a bind variable parameter(s) and in the application module you have 10 instances of that VO with appropriate values set for the bind variable in each instance.
Or if you are using the LOV feature of a VO then you can set an attribute to point to one VO and then using a view cirteria applied to that specific LOV you can then "filter" the data that would appear in that LOV.
Does that help?

Getting error while importing metadata using View Objects
Hi All,
I am trying to create a repository using View Object in OBIEE 11.1.5.1 but getting error while viewing the data, after importing the metadata in the repository "[nQSError: 77031] Error occurs while calling remote service ADFService11G. Details: Runtime error for service -- ADFService11G - oracle/apps/fnd/applcore/common/ApplSession".
I am also getting error "žADFException-2015: The BI Server is incompatible with the BI-ADF Broker Servlet: BI Server protocol version = null, BI-ADF Broker Servlet protocol version = 1" during testing my sample which is deployed to Admin server. I followed BI Adminstrator help file guide in order to create the sample for creating repository using view object.
Admin server log says

ADF BC View object with invalid character in column names
Hello
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
SrinivasThanks 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
Thanks

ADF View Criteria on a Read Only View Object
Hi,
I have created a read only view object using a query. The query consists of analytical functions to fetch the AVG values dynamically.
So far my approach worked fine.
I want the Average values in my query to be calculated dynamically based on the certain view criteria.
But after applying view criteria, my query is formulated as shown below:
SELECT * FROM (SELECT RECEIVED_YEAR,
WEEK_NO,
NO_RECEIVED,
NO_STARTED,
ROUND (TO_NUMBER (REPLACE (AVG_HRS_TO_START, ':', '.')),2) AVG_HRS_TO_START,
ROUND (AVG (TO_NUMBER (REPLACE (AVG_HRS_TO_START, ':', '.'))) OVER (ORDER BY RECEIVED_YEAR),2) OVERALL_AVG_HRS,
GOAL_HRS,
ROUND (AVG (NO_STARTED) OVER (ORDER BY RECEIVED_YEAR), 2) AVG_NO_STARTED,
ROUND (AVG (NO_RECEIVED) OVER (ORDER BY RECEIVED_YEAR), 2) AVG_NO_RECEIVED
FROM ORDERS_RCPT_TO_START_VW
ORDER BY RECEIVED_YEAR, WEEK_NO) QRSLT WHERE ( ( ( ( (RECEIVED_YEAR = :RecdYear ) AND (WEEK_NO <= :weekNo ) ) ) ) )
As per this query, it is calculating the Average values first and then applying filter criteria rather than applying the filter criteria and calculating average values.
Please help me on this.Entity objects are used to update/delete/insert data to the database.
If all your base DB object offers is read then just create a read only view object.
