Table- Why first row Selected from itself

Hi,
i have a jspx that have some fields and a button ,
the user should fill this fields with data then click the button
the button pass those values to a function that call a Stored Proceudre in the DB
then the last code in that button is to refresh a table (by execute param) that read the inserted data
why everytime the table refreshed give me the data with the first row SELECTED!!!!!!!!
i am using ADFBC + JSF
thanks in advance

Hi,
hope you handled the case where a user hits submit - or performs some other action that is performed on the current row - because you are now in an unpredictable state. Ideally you disable all related command buttons until a user selects a row

How to dynamically display the data from a table base on row selection of another table in ADF

Hi ,
I have a requirement in ADF. I need to change the data of a table based on row selection of another Table . Both the table have a Parent Child relationship between them. They have a common attribute say department_id.
                                                                                     For this I created bind variable in view object of employees table and wrote a where clause in the sql query using that bind variable. Then I created method for selection listener of department Table in java bean.
My method is following
    public void onrowselection(SelectionEvent selectionEvent) {
        RichTable richTable = (RichTable)selectionEvent.getSource();
                        CollectionModel tableModel = (CollectionModel)richTable.getValue();
                        JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding)tableModel.getWrappedData();
                        Object selectedRowData = richTable.getSelectedRowData();
                        JUCtrlHierNodeBinding nodeBinding = (JUCtrlHierNodeBinding)selectedRowData;
                oracle.jbo.domain.Number newVal = (oracle.jbo.domain.Number) nodeBinding.getAttribute("DepartmentId");
                Number pallet = newVal.bigDecimalValue();
                System.out.println("Selected values " + pallet);
        BindingContext bindingctx = BindingContext.getCurrent();
                      BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
                      DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
              DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("EmployeesView1Iterator");//access the iterator by its ID value in the PageDef file
                      ViewObject vo =dciter.getViewObject();
                      vo.setNamedWhereClauseParam("DepartmentId", pallet);//enter your value
                      vo.executeQuery();
It is printing the selected value of department id from department table in the log. But it is not able to pass the value to employees view. It is showing the following error in the log
"Definition DepartmentId of type Variable is not found in EmployeesView1."
I will be very thankful if someone helps me to solve this errror or is there any other way to achieve the same requirement.
Thanks
Nilesh

Note quite sure why you simply wont create a viewlink for the viewobject the tables are based on..
The viewlink attribute will be based on the departmentId and it's a simple master detail relationship which automatically uses ppr.
However, if both tables are on the same page; using your hack about;
On the underlying viewobject, define a viewcriteria e.g. "listById" and set your bind variable here.
I would bind table two to a RichTable component:
RichTable t2;
public void onrowselection(SelectionEvent selectionEvent) {
        RichTable richTable = (RichTable)selectionEvent.getSource();
                        CollectionModel tableModel = (CollectionModel)richTable.getValue();
                        JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding)tableModel.getWrappedData();
                        Object selectedRowData = richTable.getSelectedRowData();
                        JUCtrlHierNodeBinding nodeBinding = (JUCtrlHierNodeBinding)selectedRowData;
                oracle.jbo.domain.Number newVal = (oracle.jbo.domain.Number) nodeBinding.getAttribute("DepartmentId");
                Number pallet = newVal.bigDecimalValue();
                System.out.println("Selected values " + pallet);
               refreshTable2(pallet);
        BindingContext bindingctx = BindingContext.getCurrent();
                      BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
                      DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
              DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("EmployeesView1Iterator");//access the iterator by its ID value in the PageDef file
                      ViewObject vo =dciter.getViewObject();
                      vo.setNamedWhereClauseParam("DepartmentId", pallet);//enter your value
                      vo.executeQuery();
private void refreshTable2(Number pallet){
RichTable x=getT2();
CollectionModel cm=(CollectionModel)x.getValue();
JUCtrlHierBinding jcb=(JUCtrlHierBinding)cm.getWrappedData();
BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
DCIteratorBinding dciter = bindingsImpl.findIteratorBinding(jcb.getName()+"Iterator");
ViewObject vo =dciter.getViewObject();
ViewCriteriaManager vcm=vo.getViewCriteriaManager();

How to populate a table based on a row selection from another table.

Hi, i just started to use ADF BC and Faces. Could some one help me or point me a solution on the following scenario .
By using a search component , a table is being displayed as a search result. If i select any row in the resulted table , i need to populate an another table at the bottom of the same page from another view. These two tables are related by primary key . May i know how to populate a table based on a row selection from another table. Thanks
ganesh

I understand your requirement and the tutorial doesn't talk about Association between the views so that you can create a Master-Detail or in DB parlance, a Parent-Child relationship.
I will assume that we are dealing with two entities here: Department and Employees where a particular Department has many Employees and hence a Parent-Child relationship.
Firstly, you need to create an Association between the two Entities - Department and Employees. You can do that by right clicking on the model's entity and then associating the two entities with the appropriate key say, DepartmentId.
Once you have done that, you need to link the two entities in the View section with this Association that you created. Then go to AppModule and make sure that in the Available View Objects: 'EmployeesView' appears under 'DepartmentView' as "EmployeesView via <link you created>". Shuttle the 'DepartmentView' to the right, Data Model and then shuttle
"EmployeesView via <link you created>" to the right, Data Model under 'DepartmentView'.
This will then be reflected in your Data Controls. After that, you simply would have to drag this View into your page as a Master-Detail form...and then when you run this page, any row selected in the Master table, would display the data in the Detail table.
Also, refer to this link: [Master-Detail|http://baigsorcl.blogspot.com/2010/03/creating-master-detail-form-in-adf.html]
Hope this helps.

How to disable first row selection in a table

Hi,
I have three tables which have master child relationship. I need to enable a button for each table based on row selection of corresponding table.But first row is being selected automatically and the buttons are enabled.
what should i do in order to avoid first row selection in a table.I tried by removing selected Row Keys.But still i am getting the same problem.can anyone suggest on this.
Thank You,
Sukumar

I know a hack but I don't recommend it, anyway here it goes:
Remove selected Row Keys
Change selectionListener from the default and create a custom action listener (You can call the default one inside of it) (Tip: use makeCurrent function in this PDF
This will make sure that there is no selected row highlighted for the first time, but it actually means that the first row is selected, it's just not shown.
This method is tested with 11.1.1.7

findElementById function in javascript does not work in jdeveloper 11...
Do you help me for this?
Thanks..

Hi,
actually findElementById does work, but you should use the ADF client side framework for this. Add a clientListener to the component that intercepts the keyboard usage and make it callin the next record on the table.
I'll take a note for a how-to to put on my blog as I don't have the code ready. However, its possible this way

ADF Faces: Initially checking (radio) table's first row programatically

How can I initially check table's first row radio button programatically (from the backing bean)?
Setting current row in the iterator to be first row does not help. af:table attribute selectionState is set to bindings.PersonInformationPersonCustomers.collectionModel.selectedRow, however model is tree based - value="#{bindings.PersonInformationPersonCustomers.treeModel}"

why don´t you add on SQL Statement of your View Object an clause order by
the first row will show as the first row of you VO can view
but you can know the value of your field or your radio with a binding
open your JSP on Design view
with the right button
click on the component, your radio.
last option, Properties
at the param Binding you choose the BackingBean (or ManegedBean) and defined the name
does that you can use the name to invoke the method getValue()

How to avoid table refresh on row selection

Hi,
I have a table where the row selection happens on selecting the check box in the first column of the row. The check box is bound to the transient Boolean attribute of my VO to support this functionality which is missing in new version of ADF. The selection is working fine, however I am facing the issue with table refresh. Everytime I click checkbox to select or unselect a row my whole table is getting refreshed which is very unusual for user point of view. This is my code for the checkbox column:
<af:column sortProperty="isSelected" sortable="true"
headerText="#{bindings.pricingObjects.hints.isSelected.label}"
id="c4"
inlineStyle='#{(row.isSelected)?"background-color: #E7E7E7":""};'>
<af:selectBooleanCheckbox value="#{row.bindings.isSelected.inputValue}"
required="#{bindings.pricingObjects.hints.isSelected.mandatory}"
shortDesc="#{bindings.pricingObjects.hints.isSelected.tooltip}"
id="it4" simple="true"
autoSubmit="true">
<f:validator binding="#{row.bindings.isSelected.validator}"/>
</af:selectBooleanCheckbox>
I have to keep autoSubmit="true" on selectBooleanCheckbox because the table has to change color of the row everytime the checkbox is selected or deselected. Also, there are multiple commandToolbarButton such as "Delete" which needs to be enabled/disabled depending on the row selection.
Is there anyway, I can achieve this behaviour with minimal refresh of table?

Hi Marge,
Yes I do have Add and Delete toolbar button in the panelCollection and also set partialTrigger="tableId" on them. I need this partialTriggers because Delete button should enable/disable depending on number of rows added in the table. However, I tried removing them but it did not work for me, table is still refreshing. BUT this solution does work in combination of other solution i.e. removing ChangeEventPolicy="ppr" on the iterator. I need ppr because I have a form which is bound to the same iterator and should change on table selection. The design is like this,
- Read-only Table on top
- Editable Form below
- Select the row in table and edit the fields in the form
If I remove ppr then my form is not updating with the row selection.

can u pls explain in more details with an example?
I am telling u the scenario.
1. i have a screen(Modal dialog Box) containing ALV grid with selection buttons for each row (top part) and a subscreen(second part).
      Now when i click on a selection button, it will display the corresponding values in the subscreen.
    When this screen will display for the first time , then first row of the ALV grid should be selected and the corresponding values should be displayed in the subscreen.
i   wrote the following code in the PAI. But when i select a record its not triggering the PAI.
DATA:
     gi_index_rows TYPE lvc_t_row, " Internal table for indexes of selected rows

Can u find (number of rows) + (SELECT * FROM emp) in 1 query?

We have a requirement like this: We need to pass a SQL statement as a SYS_REFCURSOR OUT variable from a SP. Problem is, if the SQL returned 0 rows we have to send 1 row with all NULLS to the SYS_REFCURSOR.
Is there any way to find out the number of rows returned from a SQL without having to put a SELECT COUNT(*) again using the "same" SQL?

Peter:
That only works if the cursor actually returns rows. Consider:
SQL> create table t as
2 select rownum id, to_char(to_date(rownum, 'J'), 'Jsp') descr
3 from user_objects
4 where rownum <= 5;
Table created.
SQL> insert into t select * from t;
5 rows created.
SQL> commit;
Commit complete.
SQL> create function f (p_id in number) return sys_refcursor as
2     l_cur sys_refcursor;
3 begin
4     open l_cur for
5        select id, descr, count(*) over() cnt
6        from t
7        where id = p_id;
8     return l_cur;
9 end;
10 /
Function created.
SQL> var cur refcursor
SQL> exec :cur := f(1);
PL/SQL procedure successfully completed.
SQL> print cur
        ID DESCR             CNT
         1 One                 2
         1 One                 2
SQL> exec :cur := f(42);
PL/SQL procedure successfully completed.
SQL> print cur
no rows selectedSince the OP's requirement (or ""solution" coming from someone who misunderstood the concept of cursors") is that "if the SQL returned 0 rows we have to send 1 row with all NULLS to the SYS_REFCURSOR" the analytic count doesn't help.
@OP
The only reliable (for certain definitions of reliable) way would be to consume the first row of the cursor to see if it did in fact return any rows.
However, if the cursor was initally empty, we then need to generate a new cursor with all NULLS to satisfy the request. Not a big deal, as the new cursor would reflect the state of the database at the time of the initial query, even if a qualifying row was inserted and committed between the first query and the second, but it doesn't work the other way around.
If I consume the first row and find a record, then I need to re-do the query to get all of the rows. but what happens if another process changes/deletes the qualifying row in between and commits? The second query will have no rows and you will return an empty cursor to the caller.
Also, counting the rows (which the analytic count will need to do) could have a significant impact on performance since all the qualifying rows need to be read before the first row can be returned.

Reset Row Selection from Web Item Analysis in WAD 7.0

Hi All,
I have a Web Item Type Analysis and I use the Row Selection (SELECT_ROWS) value multiple.
Is there a way to reset the selection via a function?
The user select some rows and start a planning function via a button. If they would like to start the function for an other selection they first have to remove the old ones and have to mark the other lines.
A function to remove all selection from the item is needed!
PS: It is getting funny if there is paging and the selection is not even visible because it is on an other page.
Thanks for help.

Hello All.
I have exaclty the same problem now.
Is there any way to do this?
Thanks a lot and best regards,

How to render a Custom LOV Pop Up with its first Row selected

Hi All,
I have a requirement in my Custom LOV ,
I want to render my custom LOV with Query panel and resulset table in such way, where the first row is selected and the users are able to use the KEY Up and Down Arrows and Enter key to select it.
Currently, the user as to do a single Click atleast one time on a row , so that they can use their KEYs to do the selection.
How can I achieve the above requirement ? Any thoughts ?
Thanks

Hi,
The answer to your query is 'Yes'. You need to design a 'UPDATE' metadata type custom integrator. The custom integrator shall use a parameter based view to first download data and then use a PL/SQL wrapper/API to re-upload it back. The brief steps are listed below:
1. Create a 'UPDATE' metadata type custom integrator. Give a parameter list name, std/custom view for data download and a PL/SQL wrapper.
2. Create a form function and associate the form function with the custom integrator created.
3. Add the form function to the std WebADI menu for access.
4. Define a layout for the custom integrator defined.
4. To create a parameter use the standard integrator 'HR Standalone Query'. As a part of this integrator you can define the SQL WHERE clause (parameter based) that you will like to use with the custom/std view defined in the custom integrator definition.
Note: You can use a max of 5 parameters only. For each parameter, one needs to define the datatype and also the HR standalone query has a size limitation of 2000 chars in 11i10. You increase this length you may apply patch - 3494588 to get 4000 chars.
Hope this information helps.

Setting current row of a view based on row selected from another view.

Hi,
We have two Views V1 and V2. Both views are based on the same tables except that V1 is based on multiple tables. In our application we are showing a read only table which is based on V1. The user can select a particular record for edit. But the edit page is based on V2 and as a result the first record always shows up for editing even though the user may have selected another record.
Is there a way we can pass the primary key of the record selected from V1 to V2 and set that record as the current record.
We have tried setCurrentRowWithKey, but this did not help.
Regards
RHY

Hello,
post the PK as an URL parameter within the link you open the edit page. Then read this parameter in your page (the page with this link) action class and send it to an ActionBinding:
JUCtrlActionBinding action = (JUCtrlActionBinding) bc.findCtrlBinding("nameOfBinding");
ArrayList arrayList= new ArrayList();
arrayList.add(0,primaryKey);
action.setParams(arrayList);
action.doIt();
In your AppModule create a method nameOfBinding with primaryKey as in parameter
public void nameOfBinding (Number primaryKey )
getV2().setWhereClause("PRIMARY_KEY=:0");
getV2().setWhereClauseParam(0,primaryKey );
