Select new row in tree after add

In quite a few of our pages in our application we have trees and tree tables that can have rows added through separate popup windows. After the user successfully adds the record and closes the popup the tree/treetable is refreshed properly, however we also want the new node/row to be selected, and also make sure that it's parent is expanded. We've found a variety of examples of logic that does something close or sort of close, but we're having difficulties. Is there any easy or even moderate way to find a node/row in a tree based on the VO's primary key or some other value? I think I know how to make the found node/row selected and it's parent expanded, but how do I find the node/row? I keep running into issues because the tree isn't necessarily completely expanded or because the range of rows in the iterator isn't huge and the new row isn't in the initial range of rows pulled back.

Hi,
I just posted a demo and source code on my blog: Auto select New Item in Tree component
In above example i use loopAndFind() custom function.
Hope it helps!

Auto select new item in tree

Hi
I have a tree that i allow user to drag and drop items to it - what is the easiest way so the new item is automatically selected? ie, tree.selectedIndex should point to the new item's index.
Unfortunately it thought this was easy apparently it was not - like if the nodes in the tree control are collapsed, the selectedIndex is different than when all the nodes are expanded.
Do note that the way i populate my tree is through a data provider - so i populate a class that would become the tree's data provider, so when the tree refreshes, i simply do this:
myTree.dataProvider = project.p;
I can track where my new item was inserted in my "project" instance - but like i said earlier, the tree itself have different selectedIndex when the nodes are collapsed and when they are not.
THanks

Creation of new Row in Tree Table

We are creating a new row using CreateListener which is written in Bean, after creating the row, we are adding it to the iterator and the new row is not getting highlighted and focus is not in new row in the table by default. It takes an click to make it editable. 'setActiveRowKey()' method didnot help here which is used in the af:table component to achieve the same.
Any pointers regarding this issue would be helpful..
Thanks,

Hi Max:
According to what you described, it's really wierd. An ADF table is Surrounded by a panelCollection or not doesn't matter in terms of CreateInsert operations, I think. Also each step you said OK doesn't mean that step is 100% problem free towards your final goal. For example, when you drag and drop and ADF table onto a JSF page, you forget to turn on 'row selection', it will be OK, you won't get any error message, but later on when you find that you need to turn it back on, you have to go back to JSF page source, to manually added codes to do so.
The simpliest solution and quickest one is to reinitiate a clean ADF project and do it all over again. It's simple straightforward in my view. Probably don't use PanelCollection first, just drop your ADF table on a form, or af:panelForm, but make sure your table and 'CreateInsert' button is surrounded by a form, otherwise, when you click on 'CreateInsert', nothing will happen. When everything works, then probably back it up and replace your form or af:panelForm with panelCollection. See how it goes.
Thanks,
Alex

EDIT method doesn't work after adding new row

I would like to start editing after adding new row into TableView.
I copied example from Oracle website: [Using JavaFX UI Controls - 13 Table View|http://docs.oracle.com/javafx/2/ui_controls/table-view.htm#CJAGDAHE]. Then I put additional button for adding new row and define action for the button.
    final Button addButton = new Button("Add");
    addButton.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent arg0) {
            Person p = new Person("", "", "");
            table.getItems().add(p);
            table.getSelectionModel().select(p);
            table.edit(table.getSelectionModel().getSelectedIndex(), table.getColumns().get(2));
    });In result I can see selected new row but the table doesn't start edditing in the third column.
I have similar method for editing existing rows and it works properly.
    final Button editButton = new Button("Edit");
    editButton.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent arg0) {
            table.edit(table.getSelectionModel().getSelectedIndex(), table.getColumns().get(2));
    });Could you help me what I do wrong?

Try wrapping the setCaretPosition(...) method in a SwingUtilities.invokeLater(...)
caret=outputArea.getDocument().getText(0,outputArea.getDocument().getLength()).length();Should be:
caret = outputArea.getDocument().getLength();

Add new row to a table bound to ArrayList in backing bean

Hi,
I have a Arralist<CustomObject> in the backing bean.
I want to create a table with Add/Delete new row buttons which will add/delete objects from the ArrayList.
I am using Jdev 11g and I am not using ADF BC.
Please give me some heads up or links.
Thanks

Then that's your problem, change the class to something like:
public class TableHandlerConsumer
    private static final String LIST_PAGE_FLOW_ATTR = "consumers:" + TableHandlerConsumer.class.getName();
    public TableHandlerConsumer()
        Collection data = new ArrayList<Consumer>();
        buildModel(data);
        tableModel = new SortableModel(data);
        Map<String, Object> pageFlowScope = RequestContext.getCurrentInstance().getPageFlowScope();
        pageFlowScope.put(LIST_PAGE_FLOW_ATTR, tableModel);
    private void buildModel(Collection data)
        baris.add(new Consumer("", "", "", "", ""));
        baris.add(new Consumer("", "", "", "", ""));
        baris.add(new Consumer("", "", "", "", ""));
    public void addRow()
        Consumer consumer = new Consumer();
        ((Collection)tableModel.getWrappedData()).add(Consumer);
    public SortableModel getTableModel()
        Map<String, Object> pageFlowScope = RequestContext.getCurrentInstance().getPageFlowScope();
        return (SortableModel)pageFlowScope.get(LIST_PAGE_FLOW_ATTR);
}Note that if you're using 10g then change Requestcontext to AdfFacesContext and getPageFlowScope to getProcessScope

Adding a new row programatically

I have the following use case :
1) I have a jsf page having adf table which displays all the records from the employees table of hr schema.
2) pagination was implemented on this table and this table contains two buttons "Add New Row" and "Save".These buttons will be displayed in every page.
3) when the "Add New Row" is clicked,a new row has to be inserted as the last record of adf table in jsf page.
i.e suppose if the employees table contains 45 records,the adf table in my .jspx page displays 5 pages(each page contains 10 records).If i click "Add new row" button in page 2,the new record should be inserted as the 46th record in the 5 th page and the control should transfer to 5th page to enter the values for the new row.
4)After entering the values and save button is clicked,all the values of newly inserted rows should be inserted into the database.
How to acheive this functionality.
I did the following :
1)created the entity and view objects.
2)written a bussiness method in AMImpl to insert a new row when the 'Add new row" button is clicked.But this method is inserting the new row as the last record in the same page that I performed the operation.
Below is my code snippet :
public void addNewRow(){
Row newRow=getEmployeeObj().createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
EmployeeUVOImpl vo = (EmployeeUVOImpl)getEmployeeObj();
int res=vo.getFetchedRowCount()/vo.getRangeSize();
int remin=vo.getFetchedRowCount()%vo.getRangeSize();
if((vo.getFetchedRowCount()%vo.getRangeSize())>0){
vo.insertRowAtRangeIndex(vo.getRangeSize(),newRow);
else{
vo.insertRowAtRangeIndex(vo.getRangeSize()-1,newRow);
Thanks in Advance,
Regards,
Siva

Hi,
the code below works in JDeveloper 11g. However, it works similar for 10.1.3 so you may want to have a look
    public String newRowAction() {
        CollectionModel tableModel = (CollectionModel) table1.getValue();
        JUCtrlHierBinding adfModel = (JUCtrlHierBinding) tableModel.getWrappedData();
        DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
        Row lastRow = dciter.getNavigatableRowIterator().last();
        Row newRow = dciter.getNavigatableRowIterator().createRow();
        newRow.setNewRowState(Row.STATUS_INITIALIZED);
        int lastRowIndex = dciter.getNavigatableRowIterator().getRangeIndexOf(lastRow);
        dciter.getNavigatableRowIterator().insertRowAtRangeIndex(lastRowIndex+1, newRow);
        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
        //table should have its displayRow attribute set to "selected"
        AdfFacesContext.getCurrentInstance().addPartialTarget(table1);
        return null;

To add new row with the checkbox selected ....

Hi All,
In my project I have to create a table with 2 columns, 1 column is checkbox and other column is String type. In the same JFrame one textarea and one add button should be there. When we type text in the textarea and click add button, it should add a new row in the table with the checkbox selected and the 2nd column containing the text.
I want to use AbstractTableModel.
Please help me to solve this issue. If you have sample code that will be more helpful.
Thank you,
Regards,
mkumar

It would be better if you extend from DefaultTableModel rather than from Abstract Table Model. That is because DefaultTableModel provides functionality to add a row. In fact, you can directly use DefaultTableModel .
In the button's action performed,
public void actionPerformed(ActionEvent e)
if(e.getSource() == bAdd)
    Vector newRow = new Vector(2);
    newRow.add(new Boolean(Boolean.TRUE));
    newRow.add(" ");
    DefaultTableModel dm = (DefaultTableModel)yourTable.getModel();
    dm.addRow(newRow);
}Note : For the above code, Initialize the JTable with a DefaultTableModel parameter than directly with Vectors/ Arrays.
This is because when we try to cast from TableModel to DefaultTableModel as in the above code, there is a possibility of an
Exception if the Table is not initialized without a model.
For the CheckBox in the first column, you need to set an editor and a renderer so that you can manipulate and see your boolean values as the state of the check boxes.
JCheckBox b = new JCheckBox();
DefaultTableCellRenderer dr = new DefaultTableCellRenderer(b);
DefaultTableCellEditor de = new DefaultTableCellEditor(b);
yourTable.getColumnModel().getColumn(0).setCellEditor(de);
yourTable.getColumnModel().getColumn(0).setCellRenderer(dr);That should do it !

Hi,
have you seen this ?
http://download.oracle.com/docs/cd/E21764_01/apirefs.1111/e12419/tagdoc/af_fileDownloadActionListener.html
If you want to continue with your approach, then a way out of your problem could be to add an af:clientListener onto the command button. The JavaScript function would be
function onDownload(evt){
evt.noResponseExpected();

Af:table and selectOneChoice, creating a new row resets selected value

Hello,
I have a table containing 4 columns, first two are read-only (outputtext) and next 2 contains selectOneChoice , table model is baed on java.util.List
adding a new row, works fine but it resets the selectOneChoice(dropbox) selected value to First Index For All Rows
so everytime you add a new row, it resets the value to the very First Value in the dropbox for all rows,
it seems after PPR it loses the selected value in SelectOneChoice for each row...
any ideas?
Thanks,

Hi,
What is the EL expression given for value property of selectOneChoice list?
I guess it is the bean variable and it is same for each row, due to which selection in any selectOneChoice list in table modifies the same bean variable and sets the same value for lists in all other rows too(same happens in case of new insertion also, when you insert new record selectonechoice list points to the first value if no selection item is not added), in case of selectonechoice list you need to handle the selected values differently for each row. If you can share sample code, I can tell you what could be the problem.

Creating new row right after popup opens (JBO-35007 because of trigger)

Hi,
I have the same popup (with an ADF form) to add and to edit data. But i have two buttons which displays this popup - Add new and Edit, Edit works OK, on add, i insert new record like this:
        DCIteratorBinding dciter =
            (DCIteratorBinding)bindingContainer.get(iterator);
        ViewObject view = dciter.getViewObject();
        Row newRow = view.createRow();
        view.insertRow(newRow);
        view.setCurrentRow(newRow);before popup is open. And it adds a new record. But the record has id -10 (or some other negative number). This -10 is shown on calling page (the page from which the popup is open) in ADF ReadOnly table as -10 as id and other cells in row empty. That shouldn't happen (se bellow why). User then edits empty form in popup, and commits - then i get JBO-35007 because -10 changed to 123 - because of trigger.
I tried to requery - it doesn't help, see Refresh after pop-up window closes.
Can you suggest a solution on how to create a row right after popup opens?
Also,
i create new record on button's LaunchListener method. This method seems to execute before popup is open and so it affects the calling page also. I think the problem would be solved if new row would be created after popup is opened, not while opening it. (clicking create in popup works fine)

in my real case, i usually don't show ids; but to simplify debugging, i created test project where i show as many things as possible.
you mean, creating new record like following?
        bindings.getOperationBinding("Create").execute();I don't use that because i don't get empty fields in popup window (although new record is created). Actually, i don't know how to set this created record to be selected one. Suggestions?
And I did some more testing, if I create new record with clicking on Create (not creating new row automatically), i get JBO-35007 only if there was selected any other than the first row in table.
and i tried to move create method binding in pagedef, so it's the first one.. But it seems like there is no effect.
btw, i found this in one of examples on web:
   <invokeAction Binds="Execute"
                  id="refreshTableViewObjectAfterAddingNewApp"
                  Refresh="prepareModel"
                  RefreshCondition="#{processScope.addedNewApp}" />refresh condition must be true when adding new row and false for everything else. I'm not sure what that does, but it seems to work... :)
I really shouldn't use the same View Objects in popup and 'master' page, should I?

JTable checkboxes doesn't retain their selection when a new row is added!!

previouslu i was using the setElement method. now i have replaced with the addRow method...
but anyways...the control is not going to any of these overridden methods...and none of the elements are added to the table. But i comment of all the addRow, getValueAt, getColumnClass methods...then it's adding rows to the table but with only the first column all the remaiing columns are just empty...
i am fed up with this...if you observe i have commented out somany lines...becoz i am trying to save my boolean array values into a vector..but that was also in vain...
i appreciate for ur help...
thanks

Need to add a new row at the end of the table

Experts,
working jdev 11.1.1.3.0
i am adding row programetically, my requirement need to add the row at after last row.
i tried different ways.
Row newLastRow = getPWBBidLaneVO().last();
int lastRowIndex = getPWBBidLaneVO().getRangeIndexOf(newLastRow);
getPWBBidLaneVO().insertRowAtRangeIndex(lastRowIndex - 1,
laneRow);
this is giving --- java.lang.ArrayIndexOutOfBoundsException: 0
and
http://kohlivikram.blogspot.com/2008/10/add-new-row-in-adf-table-on-button.html --- its giving index out of bound because vo.getRangeSize() is 25. We set this value at vo for performance improment suggestions.
is there a way to add a new row at the end of the table?

Add this to the view row impl class
       public void insertRow(Row row) {
           //go to the end of Rowset if it has rows
           Row lastRow = this.last();
           if (lastRow !=null){
                //insert new row at the end and make it current
               int indx = this.getRangeIndexOf(lastRow)+1;
               this.insertRowAtRangeIndex(indx,row);
               this.setCurrentRow(row);
           }else { // empty Rowset
           super.insertRow(row);
           }

Trying to add a new row to a JTable

I'm having trouble adding a row dynamically to a JTable. I've been able to populate the table with an array and that works well, but how do you add new rows after the program is running?

You need to make TableModel that does dynamic resizing od the underlying data 2d array. This one will resize for both rows and columns.
    private Vector dataNames= new Vector();
    private Vector dataData =new Vector();
        javax.swing.table.TableModel dataModel = new javax.swing.table.AbstractTableModel()
            public int getColumnCount()
                return dataNames.size();
            public int getRowCount()
                return dataData.size();
            public Object getValueAt(int row, int col)
                try
                    java.util.Vector v=(java.util.Vector)dataData.elementAt(row);
                    return v.elementAt(col);
                catch(Exception e)
                    System.out.println("e :"+e.getMessage());
                    return null;
            public String getColumnName(int column)
                return (String)dataNames.elementAt(column);
            public Class getColumnClass(int col)
                if(getValueAt(0,col)!=null)
                    return getValueAt(0,col).getClass();

                            dataData.addElement(new java.util.Vector());
                            java.util.Vector v2=(java.util.Vector)dataData.lastElement();
                            v2.setSize(getColumnCount());
                    else
