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

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

Reg Row Selection in a Table

Hi All,
I am facing a problem with row selection in a table. When I navigate from one screen to another in my application, the selected rows in the previous screen should be populated in the table in the next screen.
If I have to use checkboxes inside the table for multiple row selection, how could I populate the table in the next screen with all the selected rows of the table from the previous screen.
Also, is it possible to select multiple rows in a table without using checkboxes, and by selecting the "selection mode" of table as "multi", so that initially when the page is loaded no record (row) should be selected automatically.
Please help me regarding this.
Regards,
Murthy.

Hi,
As Armin suggested you can use the inbuilt multiselection property of the table.
For populating the selected values in a table in second view
First view Context structure
-EmpDetails (Table node) (cardinality 0..n,selection 0..n,intializeleadSelection - false)
---EmpID (table column)
---Name (table column)
Second View Context structure
-DispalySelected (Table node)-EmpDetails (Table node) (cardinality 0..n,intializeleadSelection - false)
--- ID(table column)
--- Name(table column)
create a navigation link form first view to second view
In the InBoundPlug of second view
    wdContext.nodeDisplaySelected().invalidate();
    for(int i=0;i<wdContext.nodeEmpDetails().size();i++)
         if(wdContext.nodeEmpDetails().isMultiSelected(i))
               IPrivateDisplayView.IDisplaySelectedElement ele = wdContext.nodeDisplaySelected().createDisplaySelectedElement();
               wdContext.nodeDisplaySelected().addElement(ele);
               ele.setID(wdContext.nodeEmpDetails().getEmpDetailsElementAt(i).getEmpID());
               ele.setName(wdContext.nodeEmpDetails().getEmpDetailsElementAt(i).getName());
<b>For multiselecting you have to use Ctrl tab</b>

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.

Read first row of the internal table

Dear All,
Please let me know how to read the first row of the internal table?
I used following read statement but it is not working
READ TABLE t_cdhdr INDEX 1.

Hi,
i think you are not reading an internal table
according to your code i think you are reading a type
which may be declared as types...
types are declared just for reference
eg
types: begin of t_cdhdr .
include strucuture cdhdr .
types: end of t_cdhdr .
types: t_it_cdhdr type standard table of t_cdhdr.
data: git_t_cdhdr type t_it_cdhdr.
data: gwa_t_cdhdr type t_cdhdr.
now have to fill the iternal table
and
read table git_t_cdhdr into gwa_t_cdhdr index 1.
reward points if helpful
thanks & regards,

Reg Row Selection in a Table UI Element

Hi All,
Can anyone help me in writing code to select a row from a table.
I need to read the data from a row selected in a table and print it in the next page of my application.
I request anyone to send me some coding line on how to select a row from a table and read data from it.
Regards,
Murthy.

Hi Narayana,
Follow the steps.
Step1: Create a WD Component.
Step2: Under Component Controller create a
i) 2 Node EmployeeInfo and EmployeeRecord with attribute EmployeeName and Position of cardinality 0..n for both the node and a context attribute WindowInstance of type com.sap.tc.webdynpro.services.session.api.IWDWindow
Step3: Go to the Diagram View. Do the mapping between EmployeeView and Component Controller and between DisplayView and Component Controller
Step4: Design 2 Views layout
i>EmployeeView
Layout like
Employee Name |                                  Employee Position
EmployeeInfo.EmployeeName| EmployeeInfo.Position
EmployeeInfo.EmployeeName| EmployeeInfo.Position
DisplayResultButton
ii>DisplayView
Layout like
Employee Name   |                      Employee Position
EmployeeRecord.EmployeeName |    EmployeeRecord.Position
EmployeeRecord.EmployeeName |    EmployeeRecord.Position
CloseWindowButton
Step5: Create 2 Windows
1>EmployeeWindow
2>DisplayWindow.
Under EmployeeWindow add the EmployeeView
and DisplayWindow add the DisplayView
Step5: Associate action DisplayResult with the DisplayResultButton and use this code inside the Implementation of EmployeeView
public void wdDoInit()
    //@@begin wdDoInit()
//initialize nodes
wdContext.nodeEmployeeInfo().addElement(wdContext.createEmployeeInfoElement());
wdContext.nodeEmployeeRecord ().addElement(wdContext.createEmployeeRecordElement());
    //@@end
public void onActionDisplayResult(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDisplayResult(ServerEvent)
try
IPrivateDisplayView.IEmployeeRecordElement empRec =
wdContext.createEmployeeRecordElement();
int n = wdContext.nodeEmployeeInfo().size();
int leadSelected = wdContext.nodeEmployeeInfo().getLeadSelection();
// loop backwards to avoid index troubles
for (int i = 0; i < n ; i++) {
if (wdContext.nodeEmployeeInfo().isMultiSelected(i) || leadSelected == i) {
empRec.setEmployeeName(wdContext.nodeEmployeeInfo().getElementAt(i).getAttributeValue("EmployeeName"));
empRec.setPosition(wdContext.nodeEmployeeInfo().getElementAt(i).getAttributeValue("Position"));
wdContext.nodeEmployeeRecord().addElement(empRec);
catch(Exception e)
e.printStackTrace();
IWDWindowInfo windowInfo =(IWDWindowInfo) wdComponentAPI.getComponentInfo().findInWindows(
     "DisplayWindow");
//        create the Window
     IWDWindow window = wdComponentAPI.getWindowManager().createWindow(windowInfo, true);
     window.setWindowPosition(WDWindowPos.CENTER);
     window.setTitle("WindowTitle");
     window.setWindowSize(200,200);
//        Save WindowInstance in Context
     wdContext.currentContextElement().setWindowInstance(window);
//        and show the window
     window.show();
     //wdThis.wdFirePlugInDisplay();
    //@@end
Step6: Associate action CloseWindow with the CloseWindowButton
and use this code inside implementation of DisplayView
public void onActionCloseWindow(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionCloseWindow(ServerEvent)
   IWDWindow window = wdContext.currentContextElement().getWindowInstance();
   window.destroyInstance();
    //@@end

Read only af:table first row select and focus on form load

I use a read only af:table in my page. When my page loads and I click on my table, then I can use up / down arrow keys to navigate in my table's rows. But if I don't click on the table, I can't navigate in my table's rpws.
What can do in my page to give the first focus to my table's first row and navigate in my rows without using mouse clicks....
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

    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.

Only first row of a mysql table is updated

Hi,
I'm using Netbeans 5.5 with Visual Web Pack and trying to update data, stored in a mysql table.
I use a dropdown list to select a row and show the data in various textfields. This works fine. The problem, that it's not possible to save changes, I enter in the textfields. Everytime only the first row of the table will be (over)written. This happens also with the derby database. I checked the tutorial about inserting, updatting and deleting, it works fine. But they use a table to make changes to the data, so the case is different from mine.
Can anybody give me a hint? I'm going crazy ...
Thanx in advance
Markus

yes this sounds crazy. i encountered similar problem with textfields. if they are numerous type, don't forget to add integerConverter to the textfield. it helped me out in my case. hope this helps

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
TK

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.
Thanks,

Row selection across multiple tables

Hi
I currently have multiple tables where, if the user selects a particular row or group of rows in one table the correspondign row or group of rows is selected in the other table.
At the moment I've acheived this by placing listSelection listeners on all the tables so that when the selection on one table changes it fires an event and updates the slection on the other tables using:
secondTable.setRowSelectionInterval(
firstTable.getSelectedRows()[0],
firstTable.getSelectedRows()[firstTable.getSelectedRowCount() - 1]
);This works fine if the user selects a single row or a continuous group of rows. THe problem is if the user selected a non-continuous group, or selects a continuous group and then deselects some of these rows.
Because the method I've got selects all rows between the start and finish of the selection it means rows are highlighted on the other tables that are not highlighted on the first table.
My thoughts on how to approach this would be to cycle through the array of selected rows and select the corresponding rows in the other tables individually rather than selecting a range, but I can't see how to accomplish this. Could anyone give me some pointers or suggestions.
Thanks

What you are doing is correct in principle (use a
listener to propagate the selection)
Always a good start :-)
but you need to
understand the subtleties of the ListSelectionEvent -
read the API carefully - it gives you a range of
indices which may have changed but does not tell you
whether any specific indices in that range are
selected or unselected.
That makes sense, the event just indicates that the selection has changed yes?
For that you will need to get
the source ListModel from the event and query each
row in the event range to determine its selection
state.
This is where I run into difficulty. I think I can go through the each row and find out if its selected or not (using isSelectedIndex(i))
What I'm unsure what to do is how to set that for the rows in the other ListModels. What I would have normally done would be something like
otherListModel.getIndex(i).setSelected(firstListModel.isSelectedIndex(i));But as the api doesnt list the methods to do that I think I might not have got this concept sorted in my head. Could someone provide me with some pointers?
Thanks

Row Selected in a table

Hi,
I have a table on a view of my dynpro and by default the first row is selected.
How I can show my table without any row selected?
Tks a lot.

Hi,
In your view go to the method WDDOMODIFYVIEW and use the following code to deselect the row.
DATA: o_node_output_data TYPE REF TO if_wd_context_node.
o_node_output_data = wd_context->get_child_node( name = '<context table name>' ).
o_node_output_data->set_lead_selection_index( o_node_output_data->no_selection ).
Let me know if that works.
