Hi Abhijeet,
I tried it the way you said using
     wdContext.nodeBirhtday_List().nodeItab().moveFirst();
     //     loop backwards to avoid index troubles
     for (int i = n - 1; i >= 0; --i)
          current_date = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getDate();
          current_month = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getMonth();
          if (( current_date != date_today ) && ( current_month != month_today ))
               wdContext.nodeBirhtday_List().nodeItab().removeElement(wdContext.nodeBirhtday_List().nodeItab().
                              getElementAt(i));
          wdContext.nodeBirhtday_List().nodeItab().moveNext();
It adds records...
According to Valerys Solution, the IPrivate<CustomController> doesnt show me the required nodes. and gives me 'Unable to resolve' error.
Can you please suggest where I am going wrong

Hi,
All the thing you have to do is to return a boolean for the column. JTable will use a checkbox (as default) to show boolean values.

Delete row in JTable

Hello I am new To JAVA SWING
I have 2 questions related to JTable
1) How do i remove selected row in JTable ...for instance, I click on the row to delete (It is selected) , later I press the delete button, and then row is removed .... any hints ?
2) If I would like to save the rows in a JTable into a database , .... How can iterate through the rows in the JTable..each row .... the rows are saved in a List object...and a List Object is what I pass as a parameter in a class method in order to be saved into Database.
Thanks,
deibys

1) use the removeRow(...) method of the DefaultTableModel
20 use table.getModel().getValueAt(...) to get the data from the model and create your list Object.

Deleting a dataTable item after sorting

Hello,
I am using a "h:dataTable" which has a 'delete' commandLink on every row.
If I sort the table and then delete an item, the wrong item is deleted.
The deleted item is the item that was originaly in the same place (before sorting).
What should I do to fix that?
Thank you,
Dana

Should I call "sortDataList" before deleting the item the way it was sorted in the previous request?
If so, the function should receive an "ActionEvent event".
public void sortDataList(ActionEvent event) {
String sortFieldAttribute = getAttribute(event, "sortField");
}What should I send as the parameter to the sorting function?

Add/delete row in JTable

I went through the tutorial of JDK about how to programming JTable, i can NOT find a way to add/delete row into/from JTable.
I immagine it would be a difficult task because the data set it takes 'Object data[][]' is NOT dynamically grow/shrinkble.
Can we make it take ArrayList[] as input dataset so that the dataset can dynamically grow/shrink?
Any other way around to add/delete row?
THANKS for your consideration.

You have to write your own TableModel like extending AbstractTableModel. In that class add custom methods to add and remove rows. From those methods call fireTableRowsDeleted(..) and fireTableRowsInserted(..) to update UI.

Facing problem While deleting rows and adding rows

Hi,
In my form i have pass values to table rows by selecting values from Dropdown list.
i have taken 3 hidden obj and passing the dropdown values to hidden objects and then from hidden objects to table rows.
h1,h2,h2 are hidden obj
EMPNO,EMPNAME, DESIGNATION are drop downlist
i have add button with the following code
if(form1.P1.ItemSet.EMPNO.rawValue != null){
form1.P1.ItemSet.instanceManager.addInstance();
form1.P1.execInitialize();
var dynamicArray = form1.P1.resolveNode("ItemSet[" + arrayIncri + "]");
dynamicArray .EMPNO.rawValue = form1.P1.hidden.h1.rawValue;
dynamicArray .EMPNAME.rawValue = form1.P1.hidden.h2.rawValue;
dynamicArray .DESIGNATION.rawValue = form1.P1.hidden.h3.rawValue;
arrayIncri++;
form1.P1.SF1.EmpID.rawValue = null;
form1.P1.SF1.EmpName.rawValue = null;
form1.P1.SF1.Designation.rawValue = null;
My delete button code is
_ItemSet.removeInstance(this.parent.index);
form1.P1.execInitialize();
My problem is adding is happening while click and deleting is happening to the perticular row but once i delete paricular row then again if i want to add new row then it is taking null values . and agian if i click add then the values are passing to the next row

Hi,
I got the answer for this query, but when i do download and upload of the files from R/3 to GRC. Still it is not showing me the new transactions which were developed in R/3.
it means when i try to add the transaction in a function, under search mode with respective of the r/3 system, it is not showing me the search results.
What i did was, i run the reports /VIRSA/ZCC_DOWNLOAD_DESC & /VIRSA/ZCC_DOWNLOAD_SAPOBJ and uploaded them as below in GRC.
Text Objects - /VIRSA/ZCC_DOWNLOAD_DESC
permissions - /VIRSA/ZCC_DOWNLOAD_SAPOBJ
For each of the download i get 2 files for each and i tried to upload both of them but no luck.
Please suggest me, as am missing anything in this process

Problem in Delete Row

Hai To All,
         Iam using PL 05 i have enable DeleteRow option. If i click the deleterow the row is deleted but after saving the entry there is null value in database. for example if i have 2 row in the matrix if i delete last row the content is deleted after that iam saving the matrix. In the database i have 2 rows one with content and other with null value..
Whts the soultion of this....
Does anyone have idea reply me....
Regards,
Anitha

Hi Anitha,
For the delete option, you need to right a small function if its going to be ur own form.
Try using the following code...
Private Sub DeleteRow()
        Dim oDBDSource As SAPbouiCOM.DBDataSource
        Dim Count As Integer
        Dim oMatrix As SAPbouiCOM.Matrix
        Try
            oDBDSource = objForm.DataSources.DBDataSources.Item("@TableName")
            oMatrix = objForm.Items.Item("3").Specific
            oMatrix.FlushToDataSource()
            oMatrix.DeleteRow(strRow)
            objForm.Update()
            'objForm.DataSources.DBDataSources.Item("@TableName").RemoveRecord(strRow - 1)
            oDBDSource.Clear()
            oMatrix.FlushToDataSource()
            oMatrix.LoadFromDataSource()
            For Count = 1 To oDBDSource.Size - 1
                oDBDSource.SetValue("Code", Count - 1, Count)
            Next
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub
Hope this helps.

Umm. A few tips:
1) You should NOT instantiate objects / initialize variables outside the constructor. And please use access-modifiers.
2) Do not make your main-class extend JFrame or implement ActionListener. Instead create a JFrame in main and use an anonymous inner class as an ActionListener
3) Why are you extending DefaultTableModel? To set the the column names as Error1, etc.? You can set the column names by using an appropriate constructor for JTable or by using setColumnIdentifiers(...). See the API.
4) The actual problem most likely lies here:
int rows = 1;
int cols = 4;Why are you defining these outside the TableModel?

Problems to delete Rows

Hi,
i want to delete all rows in a table which will be automaticlly updatet in a thread. the problem is that i get somtimes the message 9>=9 or 8>=3. did somebody know what that means ?!?

it means the row index that you are trying to remove doesnt exist.
9>=9 means that you are trying to remove row index 9 in a table that has only 9 itmes (remember its zero based)
there's probably something dodgy with you remove code.
off the top of my head try looping through with (rowcount - 1)

Delete rows from JTable

Hello
I use a JTable with a custom table model that extends javax.swing.table.DefaultTableModel.
I haven't overwrote the method
public void removeRow(int row)Now when i use this method the rows always get removed from the end. It doesn't matter which value the parameter row has.
Even when i call
myTableModel.removeRow( 0 );it removes the rows at the end of the table.
It would be nice if someone could help me with this.
Regards, Michelle

It's not so easy to do this because it's a big project, but here is the code of the table model.

        g2.fillRect(0, 0, width, height);
        g2.setPaint(oldPaint);
        for (int row : getSelectedRows())
            Rectangle start = getCellRect(row, 0, true);
            Rectangle end = getCellRect(row, getColumnCount() - 1, true);
            g2.setPaint(new GradientPaint(start.x, 0, Color.orange, (int) ((end.x + end.width - start.x) * 1.25), 0, controlColor));

            //System.out.println("rect: (" + start.x + ", " + start.y + ") + (" + (end.x + end.width - start.x) + ", " + start.height +")");

Problems on deleting rows in UIX pages

Hi,
I am new on using BC4J, Struts and uiXML and I am having some problems on it. I have tried to make a simple create/update/delete web application.
First, I have created a DataAction which PageForward displays a table with data from a view object. This page allows the user to select a row and request its deletion by clicking on a submit button.
The event triggered by the submit button calls a DataAction that displays another PageForward, composed by a read-only form, that asks for confirmation. If the user confirms, a DataAction that performs the Delete method from the view is called and the deletion is successful.
A problem occurs when I change the readonly property of the fields of the confirmation form: the row deleted is not the selected, but a random one.
I would like to know why the readonly property of the fields change the Delete method behavior. Also, an example of a simple create/update/delete struts page flow would be appreciated.
Thanks in advance.
Verner.

Verner,
Are you using JDeveloper 10g Preview or JDeveloper 9i v9.0.3?
I'm not sure what problem you are having, but I just tried to reproduce your application by doing the following in JDeveloper 10g Preview:
1) Created new business components.
2) Created a new struts-config.xml.
3) Added to the Struts config (using the page flow modeler):
3.a) Browse data action and page forward to browse.uix
3.b) Confirm data action and page forward to confirm.uix
3.c) Delete data action.
3.d) Link from browse action to confirm action for outcome "delete".
3.e) Link from confirm action to delete action for outcome "delete".
3.f) Link from confirm action to browse action for outcome "cancel".
3.g) Link from delete action to browse action for outcome "success".
4) Then I made the delete action do the deletion by dragging the Delete operation from my data control onto the Delete data action in the page flow.
5) Then I created my UI pages.
browse.uix just has a read-only table created via the Data Control palette and then a delete button that fires the "delete" event when clicked. The delete handler returns the delete outcome.
confirm.uix has a read-only form also dragged from the Data Control palette for the same data control. There's a delete and a cancel button, each of which fire an event of the same name that returns an outcome of the same name.
When I run browseDataAction, I see my table. When I click "Delete", I see the read-only form with the details for the selected row. Clicking "Delete" from the confirmation page removes the same row I saw in the confirmation page, then goes back to the browse page showing the same range but with the given row removed.
If you continue to see a problem, what exactly is wrong? It should be the case that (A) the row selected in the table, (B) the row whose details are shown in the confirmation page, and (C) the row that gets deleted are the same row. If it's not the case that A = B = C, please give more details about what values of these three rows you are seeing. Is A=B but not =C? Or is B=C but not =A?
Hope this helps,

Problem in deleting row from database in table component

Hi,
I have a table component that its content change by diffrent links.
in this table i have a hyperlink in each row to deleting that row from dataBase.
so i must get the current row .
i do it like this:
define a rowset in the page that have a delete query :
delete from response where responseID=?
in action of delete hyperlink ,i have:
Integer responseId=(Integer)responseDataProvider.
getValue("#{currentRow.value['responseID']}") ;
getSessionBean1().getResponseRowSet().setObject(1,responseId);
getSessionBean1().getResponseRowSet().execute();
but in first line occure a exception:
illigalArgument #{currentRow.value['responseID']}
thanks.

by using data table
first you should get current record (row that recived action)
then delete it by using data provider.
I do not think that you could execute delete statement using rowSets because they just can provide Select statements.
btw , following code will retrive clicked row from data table and
delete that row
try {
RowKey rk = getTableRowGroup1().getRowKey();
if (rk != null) {
testDataProvider.removeRow(rk);
testDataProvider.commitChanges();
} catch (Exception ex) {
log("ErrorDescription", ex);
error(ex.getMessage());

Problem in deleting rows

Hi experts,
in the following method. I am deleting the records from the BAPI output table where the date and month do not correspond to todays date and current month.
When I execute the BAPI for one employee it gives me the correct output. ie one record. But when I execute it for all the employees and when I use the following code. It gives me a blank output.
public void wdDoInit()
    //@@begin wdDoInit()
    int date_today, current_date;
    int month_today, current_month;
    char date_satisfied, month_satisfied;
    Date date = new Date(System.currentTimeMillis());
    date_today = date.getDate();
    month_today = date.getMonth();
     int n = wdContext.nodeBirhtday_List().nodeItab().size();
     int leadSelected = wdContext.nodeBirhtday_List().nodeItab().getLeadSelection();
     //     loop backwards to avoid index troubles
     for (int i = n - 1; i >= 0; --i) {
          current_date = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getDate();
          current_month = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getMonth();
          if (( current_date != date_today ) && ( current_month != month_today ))
               wdContext.nodeBirhtday_List().nodeItab().removeElement(wdContext.nodeBirhtday_List().nodeItab().
                              getElementAt(i));
    //@@end
can anybody please suggest me the solution
Regards
Abdullah

Hi Abhijeet,
I tried it the way you said using
     wdContext.nodeBirhtday_List().nodeItab().moveFirst();
     //     loop backwards to avoid index troubles
     for (int i = n - 1; i >= 0; --i)
          current_date = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getDate();
          current_month = wdContext.nodeBirhtday_List().nodeItab().currentItabElement().getGbdat().getMonth();
          if (( current_date != date_today ) && ( current_month != month_today ))
               wdContext.nodeBirhtday_List().nodeItab().removeElement(wdContext.nodeBirhtday_List().nodeItab().
                              getElementAt(i));
          wdContext.nodeBirhtday_List().nodeItab().moveNext();
It adds records...
According to Valerys Solution, the IPrivate<CustomController> doesnt show me the required nodes. and gives me 'Unable to resolve' error.
Can you please suggest where I am going wrong
Regards
Abdullah

Row doesn't get selected after sorting

I have a table bond to a javabean data control. I have enabled multi row selection. I get some rows on the table and then I select one of those rows, after that I use the value of the selected row for some operations.
I have 3 columns, first name, lastname , email. The first 2 are sortable. If I click on the header of firstname, the information gets sorted ok (asc / desc). The problem is that after sorting, I can NOT select any rows. When I click on the row, it doesn't get highlighted, and If I try to use the value of the selected row I get a null pointer exception.
Again this is happening only after sorting. If I don't sort, it works ok.
I'm using JDEV + ADF 11.1.1.5.
This is my code
<af:table value="#{bindings.User1.collectionModel}" var="row" partialTriggers="::cb1"
rows="#{bindings.User1.rangeSize}"
emptyText="#{bindings.User1.viewable ? identityBundle.no_data_to_display : identityBundle.access_denied}"
fetchSize="#{bindings.User1.rangeSize}" rowBandingInterval="0"
id="t1" rowSelection="multiple"
selectionListener="#{AssignRolesBean.onTableSelect}"
binding="#{AssignRolesBean.searchResultsTable}"
columnStretching="last">
<af:column sortProperty="firstname" sortable="#{AssignRolesBean.columnSortable}"
headerText="#{bindings.User1.hints.firstname.label}" id="c1"
width="136">
<af:outputText value="#{row.firstname}" id="ot4"/>
</af:column>
<af:column sortProperty="lastname" sortable="#{AssignRolesBean.columnSortable}"
headerText="#{bindings.User1.hints.lastname.label}" id="c2"
width="182">
<af:outputText value="#{row.lastname}" id="ot2"/>
</af:column>
<af:column sortProperty="mail" sortable="#{AssignRolesBean.columnSortable}"
headerText="#{bindings.User1.hints.mail.label}" id="c4"
width="361">
<af:outputText value="#{row.mail}" id="ot5"/>
</af:column>
<af:column sortProperty="uid" sortable="false"
headerText="#{bindings.User1.hints.uid.label}" id="c3"
visible="false">
<af:outputText value="#{row.uid}" id="ot3"/>
</af:column>
</af:table>
I have a selection listener only, I don't have a sort listener.
My bean;
AssignRolesBean
public void onTableSelect(SelectionEvent selectionEvent) {
GenericTableSelectionHandler.makeCurrent(selectionEvent);
My makeCurrent method
public static void makeCurrent( SelectionEvent selectionEvent){
RichTable _table = (RichTable) selectionEvent.getSource();
CollectionModel tableModel = (CollectionModel) table.getValue();
JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding) tableModel.getWrappedData();
DCIteratorBinding tableIteratorBinding = adfTableBinding.getDCIteratorBinding();
Object selectedRowData = table.getSelectedRowData();
JUCtrlHierNodeBinding nodeBinding = (JUCtrlHierNodeBinding) selectedRowData;
Key rwKey = nodeBinding.getRowKey();
tableIteratorBinding.setCurrentRowWithKey( rwKey.toStringFormat(true));
SHOULD I IMPLEMENT A SORT LISTENER FOR THIS TABLE IN ORDER TO HANDLE ROW SELECTION PROPERLY AFTER SORTING?
Is there a guideline for handling row selection after sorting?
Thanks

Delete Multiple Rows of JTable by selecting JCheckboxes

Hi,
I want delete rows of JTable that i select through JCheckbox on clicking on JButton. The code that i am using is deleting one row at a time. I want to delete multiple rows at a time on clicking on Button.
