ADF Faces Table with a Total row calculated?

Hi there OTN Community:
I have another doubt.
I have an EJB dataControl, and i use one of his collections to display the data in an ADF Faces Table. One of the columns of the Adf Faces Table is numeric, And i have to display the Total of that Column.
I only shows 10 rows per screen, but i need to show the total of all the rows.
How i can calculate it?

Mmmmm..... You're right!...I will try that.
Thanx :)
Hey, and....You know? i was thinking, maybe i can get the iterator and then capture each object of the iterator to compute the total. That is a crazy idea?, its possible?, its not recommended? or its ok too? :P
Thanx in advance.

ADF Faces table with checkboxes

Hi,
My dev env: jdev 11.1.1.2.0
I like to implement something like yahoo mail, with a checkbox at the column header. If selected,
all rows will be selected. I assume Yahoo's email is using javascript. How do I achieve the same
thing here with adf faces table? Is there any tutorial I could reference.
Thanks in advance!

You're here in the Sun JSF forum, not in the Oracle JSF forum.
Try here: JDeveloper and ADF
If the ADF datatable is technically comparable with the RI datatable, check http://balusc.xs4all.nl/srv/dev-jep-dat.html to get some insights how to retrieve the selected row object.

URGENT: ADF Faces table updating issue.

I have a project that uses JSF, ADF Faces, EJB 3.0, and the ADF binding framework.
In this project, I have a page with a databound ADF Faces Table. The table has a number of read-only columns and two read-write columns. I also have an Edit button that allows the user to pop up a dialog box to edit the selected row of the table. When the user clicks OK in the dialog box, the data is passed back to the main page and the table is updated.
Everything works correctly for the read-only columns. For the read-write columns, however, the table data does not get updated following an edit. This is what I have found:
1. The table row data gets passed in to the Edit dialog correctly.
2. The data gets passed back correctly.
3. The model gets updated correctly (up to and including the database).
4. Looking at the iterator in the debugger shows the correct, updated data.
5. When the table row is getting redrawn, the getter calls for the read-write columns return the updated data.
6. As mentioned above, the read-only columns get updated correctly.
7. Updating the read-write columns directly from the table works correctly.
So, the problem appears to be in the GUI layer. I suspect that, somehow, the submitted values of the read-write columns are not getting set properly, but I cannot figure out how to do this.
Note that clicking on the Edit button results in a partial submit. In the return listener, I add a call to AdfFacesContext.getCurrentInstance().addPartialTarget(getRecipientTable()) in order to redraw the table (getRecipientTable() is the bound value of the ADF table).
Please help! We are so close to production and we need to fix this.
Thanks,
Ara

Hi,
I don't have a testcase for this, so I just come up with ideas to try
1. refresh the parent container of the table. It seems that the input text components are not triggered to refresh if the refresh is on the table.
2. If using ADF, make sure the update is performed directly on theiterator (which automatically is the case if you use a ADF bound form for this)
3. Check if executing the table iterator and then setting back the current row makes a difference

An extra column of a query in an ADF Faces Table?

Hi to all OTN Community...
I use ADF Faces, Toplink and EJB 3.0 in JDevelooper 10.1.3.1.0, and i have a question...
I need to show in an adf faces table, the result of a query like this
SELECT COLUMN1, COLUMN2, COUNT(*)
FROM TABLEX
GROUP BY COLUMN1, COLUMN2
I do this query in the TableX named queryes...and then i have acces to this named query in the dataControl, but, when i drag and drop the dataControl to a jsf page, this only shows the columns of the tableX. Then, i want to know, ¿How can i show the count(*) column in the page in a dataControl?
PD: i want to show in the adf faces table the same result if i execute that query in an sql client.
Thanx in advance...
Darklorddany

Darklorddany,
The solution to this is to add an additional method on your EJB 3.0 session-bean that exposes an dynamic TopLink report (projection) query.
The TopLink code within the method would leverage your existing TopLink mappings to do the query like:
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);The ReportQueryResult objects are very generic map/row type containers that will not work well in your ADF binding layer. With JPA you can specify and ad-hoc Java class to contain such projection results that make them a little easier to use in clients. This functionality will be available in the next release of TopLink. Until then you will need to write some code to convert to your own result class for this query.
In my case I'll create a simple POJO like:
    public class EmployeeNameCount {
        private String firstName;
        private String lastName;
        private int count;
        public EmployeeNameCount(String firstName, String lastName, int count) {
            this.firstName = firstName;
            this.lastName = lastName;
            this.count = count;
        public String getFirstName() {
            return this.firstName;
        public String getLastName() {
            return this.lastName;
        public int getCount() {
            return this.count;
    }Now I combine the previous report query code into an EJB 3.0 session bean method:
    @TransactionAttribute(TransactionAttributeType.SUPPORTS)
    public List<EmployeeNameCount> findEmployeeNamesWithCount() {
        Session session = getSessionFactory().acquireSession();
        ReportQuery rq = new ReportQuery(Employee.class, new ExpressionBuilder());
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.addCount();
        rq.addGrouping("firstName");
        rq.addGrouping("lastName");
        List<ReportQueryResult> results = (List<ReportQueryResult>)session.executeQuery(rq);
        session.release();
        List<EmployeeNameCount> empNameCounts = new ArrayList<EmployeeNameCount>(results.size());
        for (ReportQueryResult rqr: results) {
            String fname = (String)rqr.getByIndex(0);
            String lname = (String)rqr.getByIndex(1);
            int count = ((Number) rqr.getByIndex(2)).intValue();
            empNameCounts.add(new EmployeeNameCount(fname, lname, count));
        return empNameCounts;
    }You will also need to make sure the method exists on your EJB 3.0 session bean's interface as well. Then regenerate the data control for your session bean and you should have access to drag and drop this query with its results into your JSF pages.
As mentioned this use case will be much simpler and declarative in the next release.

SQL Server 2012 Undetected Deadlock in a table with only one row

We have migrated our SQL 2000 Enterprise Database to SQL 2012 Enterprise few days ago.
This is our main database, so most of the applications access it.
The day after the migration, when users started to run tasks, the database access started to experiment a total failure.
That is, all processes in the SQL 2k12 database were in lock with each other. This is a commom case of deadlock, but the Database Engine was unable to detect it.
After some research, we found that the applications were trying to access a very simple table with only one row. This table has a number that is restarted every day and is used to number all the transactions made against the system. So, client
applications start a new transaction, get the current number, increment it by one and commit the transaction.
The only solution we found was to kill all user processes in SQL Server every time this situation occurs (no more than 5 minutes when all clients are accessing the database).
No client application was changed in this migration and this process was working very well for the last 10 years.
The problem is that SQL 2k12 is unable to handle this situation compared to SQL 2k.
It seems to occurs with other tables too, but as this is an "entry table" the problem occurs with it first.
I have searched internet and some suggest some workarounds like using table hints to completely lock the table at the begining of the transaction, but it can't be used to other tables.
Does anyone have heard this to be a problem with SQL 2k12? Is there any fixes to make SQL 2k12 as good as SQL 2k?

First off re: "Unfortunatelly, this can't be used in production environment as exclusive table lock would serialize the accesses to tables and there will be other tables that will suffer with this problem."
This is incorrect.
Using a table to generate sequence numbers like this is a bad idea exactly because the access must be serialized. Since you can't switch to a SEQUENCE object, which is the correct solution, the _entire goal_ of this exercise to find a way to properly
serialize access to this table. Using exclusive locking will not be necessary for all the tables; just for the single-row table used for generating sequence values with a cursor.
I converted the sample program to VB.NET:
Public Class Form1
Private mbCancel As Boolean = False
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim soConn As ADODB.Connection
Dim soRst As ADODB.Recordset
Dim sdData As Date
Dim slValue As Long
Dim slDelay As Long
'create database vbtest
'go
' CREATE TABLE [dbo].[ControlNumTest](

' [UltNum] [int] NOT NULL,
' CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
' [UltData] Asc
' )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 80) ON [PRIMARY]
' ) ON [PRIMARY]
mbCancel = False
Do
' Configure the Connection object
soConn = New ADODB.Connection
With soConn
.ConnectionString = "Provider=SQLNCLI11;Initial Catalog=vbtest;Data Source=localhost;trusted_connection=yes"
.IsolationLevel = ADODB.IsolationLevelEnum.adXactCursorStability
.Mode = ADODB.ConnectModeEnum.adModeReadWrite
.CursorLocation = ADODB.CursorLocationEnum.adUseServer
.Open()
End With
' Start a new transaction
Call soConn.BeginTrans()
' Configure the RecordSet object
soRst = New ADODB.Recordset
With soRst
.ActiveConnection = soConn
.CursorLocation = ADODB.CursorLocationEnum.adUseServer
.CursorType = ADODB.CursorTypeEnum.adOpenForwardOnly
.LockType = ADODB.LockTypeEnum.adLockPessimistic
.Open("SELECT * FROM dbo.ControlNumTest")
End With
With soRst
sdData = .Fields!UltData.Value ' Read the last Date (LOCK INFO 1: See comments bello
slValue = .Fields!UltNum.Value ' Read the last Number
If sdData <> Date.Now.Date Then ' Date has changed?
sdData = Date.Now.Date
slValue = 1 ' Restart number
End If
.Fields!UltData.Value = sdData ' Update data
.Fields!UltNum.Value = slValue + 1 ' Next number
End With
Call soRst.Update()
Call soRst.Close()
' Ends the transaction
Call soConn.CommitTrans()
Call soConn.Close()
soRst = Nothing
soConn = Nothing
txtUltNum.Text = slValue + 1 ' Display the last number
Application.DoEvents()
slDelay = Int(((Rnd * 250) + 100) / 100) * 100
System.Threading.Thread.Sleep(slDelay)
Loop While mbCancel = False
If mbCancel = True Then
Call MsgBox("The test was canceled")
End If
Exit Sub
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
mbCancel = True
End Sub
End Class
And created the table
CREATE TABLE [dbo].[ControlNumTest](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = on, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
go insert into ControlNumTest values (cast(getdate()as date),1)
Then ran 3 copies of the program and generated the deadlock:

It's the S lock that comes from the cursor read that's the villian here. U locks are compatible with S locks, so one session gets a U lock and another gets an S lock. But then the session with an S needs a U, and the session with a U needs an
X. Deadlock.
I'm not sure what kind of locks were taken by this cursor code on SQL 2000, but on SQL 2012, this code is absolutely broken and should deadlock.
The right way to fix this code is to add (UPDLOCK,SERIALIZABLE) to the cursor
.Open("SELECT * FROM dbo.ControlNumTest with (updlock,serializable)")
So each session reads the table with a restrictive lock, and you don't mix S, U and X locks in this transaction. This resolves the deadlock, but requires a code change.
I tried several things that didn't require a code, which did not resolve the deadlock;
1) setting ALLOW_ROW_LOCKS=OFF ALLOW_PAGE_LOCKS=OFF
2) SERIALIZABLE isolation level
3) Switching OleDB providers from SQLOLEDB to SQLNCLI11
Then I replaced the table with a view containing a lock hint:
CREATE TABLE [dbo].[ControlNumTest_t](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = on, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
go
create view ControlNumTest as
select * from ControlNumTest_t with (tablockx)
Which, at least in my limited testing, resovlved the deadlock without any client code change.

ADF Faces table selection from commandLink?

I'm using the ADF faces table component and would like to allow my users to make a selection out of the table from a click onto a commandLink rather than using the tableSelection facets. How can I determine the row they have clicked on?
Thanks for any help,

Hello
Sorry to restart this thread again, but if i do table.getRowData() i don't get any rows, the rowcount remains 0, but my table contains many data rows.
Is there anybody who knows what the reason can be?

ADF-Faces table and mass data

Hello Oracle,
we consider to use ADF-Faces with Spring and TopLink or Hibernate that supports all important commercial databases.
We need a solution for selecting mass data and show them using a ADF-Faces component.
ADF-Faces table looks great and is fine for for some hundred datasets. But we have customers who could do a select over 80.000 or more datasets and it cannot be the solution to load them completly in collection-model in memory.
Do you have a solution or do you plan somthing? A JSF data table component for mass data (e.g. load from database on every "next or "previous" click)?
Regards
Florian

I'm pretty new to ADF Faces etc. but I know the ADF Table component supports paging. If you're using ADF Business Components as the persistence framework it supports paging out of the box giving you exactly what you're looking for.
If you're using EJBs or Toplink I think you have to write your own paging interface but I don't know this for sure.

How to create editable table with one empty row ?

I'm looking for solution how to create editable table with one empty row using ADF BC. I have seen this solution in application that was created in JHeadstart and it's very well idea to use it insead of creation form.

hammm, i do it this:
drop the VO on the page, select Table->ADF Table....
so, drop the botton create, from de VO->operations->create (the firts), and right botton (mouse) Edit binding....
in Data collection select the VO, in Select an action select CreateInsert

ADF faces tables - range navigation table footer

Hi,
I have a strage situation using ADF Faces' table, sometimes it displays range navigation on top and bottom of the table and sometimes only on top of the table. Is it possible to show always the range navigation on top and bottom of the table? How? If not, can someone give me an example of using an selectRangeChoiceBar to implement navigation on bottom of the table?
Thanks in advance.
Best Regards,

Row Level PPR in Advanced Table with Add More Rows Button

<br>
I have programmatically fired PPR event on MessageChoice. But it is in Advanced Table with
Add More Rows Button. When the value is changed in MessageChoice I Show/Hide Custom LOV
through SPEL like this ${oa.BioEmployeePVO.EmpManagerRender} .
But it is <b>hiding the all the ROWS</b> not just the row where the value has been changed.
I even tried with this code and get NULL for rowReference.
String rowReference = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
In Processrequest()
String pageName = pageContext.getRootRegionCode();
     Hashtable params = new Hashtable (1);
     params.put ("param1", pageName);
     Hashtable paramsWithBinds = new Hashtable(1);
    paramsWithBinds.put ("param2",new OADataBoundValueFireActionURL (mcb, "{$AttendeeType}"));
    mcb.setFireActionForSubmit ("empPositionChange", params, paramsWithBinds,false, false);
In ProcessFormRequest() {
if ("empPositionChange".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
      String rowReference = pageContext.getParameter("param2");
    //    String rowReference = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
     Serializable[] parameters = { rowReference };
      am.invokeMethod("handlePositionChangeEvent", parameters);

HI Kumar,
Answer to your last post is "yes".
Now to your doubt regarding the code:
Hi Anna
I am trying to understand your code.
FireAction firePartialAction = new FirePartialAction("fireHideEvent"+(i/noOfTlaColSpan));
HideImgBean.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR,firePartialAction);
1. What is this i/noOfTlaColSpan ?
:)Forget abt this in your case it should be the event name which u r firing and capturing the it in the PFR.
Like FireAction firePartialAction = new FirePartialAction("YOurEventName");
and in PFR u can capture tht as:
if("YOurEventName".equals(pageContext.getParameter(EVENT_PARAM)))
//your logic to invoke AM method
2. I believe this HideImgBean would be MessageChoice for me?
:)Yep ur right
3. This brcdOhInventoryViewUpdateVOImpl would be the Custom PVO(Extending Seeded Base VO)
I create by adding the transient attributes?
:)Yep ur right
4. I cannot understand this code. Could you explain.
:)Please look at my comments in some of the lines .I have explained wht i am doing
if(updateIter==null)
updateIter[0]= invViewVO.createRowSetIterator("updateIter");//This initViewVo should be ur custom VO object
if(cnt>0)
updateIter[0].setRangeStart(0);
updateIter[0].setRangeSize(cnt);
for(int i=0;i<cnt;i++)
row = (brcdOhInventoryViewUpdateVORowImpl)updateIter[0].getRowAtRangeIndex(i);
String selectFlag=(String)row.invokeMethod("getPartNumber");//This getPartNuber should be replaced by the Prim Key inoke methd of ur VO
if(RowID.equals(selectFlag))
//This is my logic to set the transient attributes based on the msgChoiceBean value ..u have to pass the value when u invoke this method

In my AM I am doing this. Am i doing right?:)Yep u r right
BioPrescribersPVO is the custom VO(extending seeded base VO).
public void handlePositionChangeEvent(String param)
OAViewObject vo = (OAViewObject)findViewObject("BioPrescribersPVO");
OARow row = (OARow)findRowByRef(rowReference);
if (row != null)
String position = (String)row.getAttribute("AttendeeType");
if (("PRESCRIBER".equals(position)) )
// BioEmpManagerRender is the transient attribute in BioPrescribersPVO.
row.setAttribute("BioEmpManagerRender", Boolean.TRUE);
row.setAttribute("BioPresManagerRender", Boolean.FALSE);
else
row.setAttribute("BioEmpManagerRender", Boolean.FALSE);
row.setAttribute("BioPresManagerRender", Boolean.TRUE);
} // end handlePositionChangeEvent()
// Initializing the custom VO
/*No need to initialize the VO because this is not a PVO(Propeties View object)
U r just using the existing VO and tht vo shloud have a primary key.Tht way u can match the rowref u r getting with the actual row from the View object*/
public void init()
OAViewObject appPropsVO = (OAViewObject)getBioPrescribersPVO();
if (appPropsVO != null)
if (appPropsVO.getFetchedRowCount() == 0)
appPropsVO.setMaxFetchSize(0); appPropsVO.executeQuery();
appPropsVO.insertRow(appPropsVO.createRow());
OARow row = (OARow)appPropsVO.first();
row.setAttribute("RowKey", new Number(1));
handlePositionChangeEvent("");
} // end init()

Issue in adding not null constraint on 250 G table with 50 million rows.

Guys,
I need to add not null constraint on 2 column of a table with 50 million rows and ~250 GB in size, These 2 columns are newly added and I have also update the value for each of these columns to not null for each row.
After that I am adding not null constraint on these 2 columns this is taking 1 hour to complete, Is there any way to speed up this, I don't want to use ENABLE NOVALIDATE option or rather I can't use that option.

Presumably, this is a one time operation, and it doesn't really interfere with anything else.

Table with two header rows

Hello, i have a table in that table i have a header row which has another table with two header rows
When form spans more then one page on page2 the color and border are showing up outside of table see example below.
Anyone have any ideas how I can fix this?
I am using Livecycle designer ES2 9.***
THanks

Hi,
If the table spans to Next page then if you want to move whole table to other page then uncheck the allow page breaks with content option which is under Object Tab.
Thanks
