Drag'n'drop beans on a customform in BeanBox

What I actually want to do is the following:
-create a CustomBean, which is a top-level container (JFrame) itself
-then in BeanBox I would like to place other beans on this CustomBean-Frame and connect them with each other
-then I would use BeanBox's feature to make an applet
What I try to achieve is a custom BeanBox; Because I need some special feature the standard BeanBox-Container (RootPane and ComponentPane) does not implement.
But I still want to be able to use the visual-desing-mode and the automatic applet-conversion.
My idea was, to create a CustomBean (extended from JApplet), which when used as a Bean, creates a JFrame (and then inits the JApplet).
The Problem:
when using this Bean in BeanBox it is not possible to place other
beans in this CustomBean-Frame.
I can see now that this idea doe not work, but can anyone tell me
a working solution?

YOu need to OPTION drag...pressing the OPTION key after you grab the clip. And then look for the arrow curving down.

Select All in a table does not work for Drag and Drop

Hi. I am using Jdeveloper 11.1.1.2 but have also reproduced in 11.1.1.3.
I am trying to implement drag and drop rows from one table to another. Everything works fine except when I do a Select All (ctrl-A) in a table, the table visually looks like all rows are selected, but when I try to click on one of the selected rows to drag to the other table, only the row I click on is dragged.
I tried setting Range Size -1, fetch mode to FETCH_ALL, content delivery to "immediate" but nothing works.
I even have reproduced not using a view object but just a List of beans with only 5 or 10 beans showing in the table.
Does anyone know how to get Select All to work for a Drag Source?
Thanks.
-Ed

Frank-
OK, thanks for looking into that. I also submitted this service request, which includes a simple sample app to demonstrate the problem:

Thanks again for the reply.

What is the correct way to add styling to drag-and-drop created calendars?

I have a working instance of a rich client calendar. I generated the view with the required fields (start, stop, provider, ...), put it into the App Module, and dragged it onto a JSF page to create a calendar.
Next I created an activityScope object in a class called CalendarBean (no inheritance)
Class CalendarBean()
private HashMap<Set<String>, InstanceStyles> activityColorMap;
+..+
+public CalendarBean() {+
super();
activityColorMap = new HashMap<Set<String>, InstanceStyles>();
HashSet setEd = new HashSet<String>();
HashSet setLen = new HashSet<String>();
setEd.add("Work");
setLen.add("Home");
activityColorMap.put(setEd, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityColorMap.put(setLen, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.RED));
+}+
+}+
Next, I linked this up as a backing bean and associated the ActivityStyles of CalendarBean to it:
+#{backingBeanScope.calendarBean.activityColorMap}+
I populated some records in the database with properties "Work" and "Ed', but they show default blue.
As I understand it, I need to do something with the getTags() method of the underlying CalendarActivity class, but I'm not quite sure how to do that.
Took a stab at creating a class, CalendarActivityBean, that extended CalendarActivity, and pointed all the CalendarActivity references I had to the new class, but it didn't seem to fire (in debug), and I got into trouble, when inserting records, with
public void calendarActivityListener(CalendarActivityEvent calendarActivityEvent) {
currActivity = (CalendarActivityBean) calendarActivityEvent.getCalendarActivity();
being an illegal cast
What is the correct way to add provider-based styling to drag-and-drop create calendars?
Ed Schechter

A colleague of mine was kind enough to solve this:
The calendar has ActivityStyles property = #{calendarBean.activityStyles}
CalendarBean looks something like this:
package com.hub.appointmentscheduler.ui.schedule;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Set;
import oracle.adf.view.rich.util.CalendarActivityRamp;
import oracle.adf.view.rich.util.InstanceStyles;
+public class CalendarBean {+
private HashMap activityStyles;
private String dummy;
+public CalendarBean() {+
+// Define colors+
activityStyles = new HashMap<Set<String>, InstanceStyles>();
HashSet setPending = new HashSet<String>();
HashSet setArrived = new HashSet<String>();
HashSet setApproved = new HashSet<String>();
HashSet setCompleted = new HashSet<String>();
setApproved.add("APPROVED");
setPending.add("PENDING");
setArrived.add("ARRIVED");
setCompleted.add("COMPLETED");
activityStyles.put(setApproved, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.GREEN));
activityStyles.put(setPending, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.ORANGE));
activityStyles.put(setArrived, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.PLUM));
activityStyles.put(setCompleted, CalendarActivityRamp.getActivityRamp(CalendarActivityRamp.RampKey.LAVENDAR));
+}+
+public void setactivityStyles(HashMap activityStyles) {+
this.activityStyles = activityStyles;
+}+
+public HashMap getactivityStyles() {+
return activityStyles;
+}+
+}+
Now, go into the Bindings tab on the calendar page, double click the calendar binding, and specify the column you've defined as the calendar's Provider in the Tags dropdown.
Should show colors.

NamedViewCriteria not working when drag and dropped as filtered table.

Using JDev 11.1.2.1.0.
I'm attempting to use NamedViewCriteria more and more because, well ... I keep reading it's the way to go. But I'm encountering an aggravating problem. I can't get them to work when I drag and drop as a filtered table onto a page. They work when I apply them in a managed bean, but simply dragging and dropping will not trigger the NamedViewCriteria to display the filtered items correctly.
Creating a where clause manually works fine.
Manual Where Clause & drag and drop ViewObject from data control
(:pBpKey is null or upper(BP_KEY) like '%' || upper(:pBpKey) || '%') AND CinderBusinessPartners.BP_TYPE = 'C'NamedViewCriteria & drag and drop from ViewObject's NamedViewCriteria from data control
( ( (CinderBusinessPartners.BP_KEY LIKE ('%' || :pBpKey || '%') ) AND (CinderBusinessPartners.BP_TYPE = 'C' ) ) )There are three problems:
1) The query pulls back all items. It doesn't retrieve only where BP_TYPE = 'C'.
2) It is case sensitive. i.e. Enter in A will not pull back the customer Wal-Mart because Wal-mart contains lowercase a's.
3) If I set the table's "Show Filter" attribute to true, the filter has the text "\*pBpKey\*" filled in by default. uhhh What?
In the NamedViewCriteria's "UI Hints" tab, I have the "Query Automatically" checkbox selected.
Any ideas why the NamedViewCriteria isn't "just working"?
I'll be back with pictures after the break.

How to drag and drop tab nodes between tab panes

I'm working on example from this tutorial( Drag-and-Drop Feature in JavaFX Applications | JavaFX 2 Tutorials and Documentation ). Based on the tutorial I want to drag tabs between two tabs. So far I managed to create this code but I need some help in order to finish the code.
Source
tabPane = new TabPane();
Tab tabA = new Tab();
   Label tabALabel = new Label("Main Component");
tabPane.setOnDragDetected(new EventHandler<MouseEvent>()
            @Override
            public void handle(MouseEvent event)
                /* drag was detected, start drag-and-drop gesture*/
                System.out.println("onDragDetected");
                /* allow any transfer mode */
                Dragboard db = tabPane.startDragAndDrop(TransferMode.ANY);
                /* put a string on dragboard */
                ClipboardContent content = new ClipboardContent();
                content.put(DataFormat.PLAIN_TEXT, tabPane);
                db.setContent(content);
                event.consume();
What is the proper way to insert the content of the tab as object? Into the tutorial simple text is transferred. How I must modify this line content.put(DataFormat.PLAIN_TEXT, tabPane);?
And what is the proper way to insert the tab after I drag the tab:
Destination
tabPane.setOnDragDropped(new EventHandler<DragEvent>()
            @Override
            public void handle(DragEvent event)
                /* data dropped */
                /* if there is a string data on dragboard, read it and use it */
                Dragboard db = event.getDragboard();
                boolean success = false;
                if (db.hasString())
                    //tabPane.setText(db.getString());
                    Tab tabC = new Tab();
                    tabPane.getTabs().add(tabC);
                    success = true;
                /* let the source know whether the string was successfully
                 * transferred and used */
                event.setDropCompleted(success);
                event.consume();
I suppose that this transfer can be accomplished?
Ref javafx 2 - How to drag and drop tab nodes between tab panes - Stack Overflow

I would use a graphic (instead of text) for the Tabs and call setOnDragDetected on that graphic. That way you know which tab is being dragged. There's no nice way to put the Tab itself into the dragboard as it's not serializable (see https://javafx-jira.kenai.com/browse/RT-29082), so you probably just want to store the tab currently being dragged in a property.
Here's a quick example; it just adds the tab to the end of the current tabs in the dropped pane. If you wanted to insert it into the nearest location to the actual drop you could probably iterate through the tabs and figure the coordinates of each tab's graphic, or something.

Drag and Drop using iterator in ADF 11.1.1

I am looking for a workaround for the following problem.
<af:componentDragSource> returns an incorrect dragComponent value when dropped on a dropTarget when container elements are generated by an iterator.
Below is sample code:
in jspx file:
                     <af:panelGroupLayout>
                         <af:outputText value="Drag object 1"/>

            return DnDAction.MOVE;
        } else {
            return DnDAction.NONE;
    }Drag a 'drag object' from the hard coded top group and drop it on a yellow drop target in the same group.
Output from System.out will be correct.
Do the same for the second iterator-generated group. You will find that the 'dragged' value in the bean code returns the same value as the 'dropped' value. In other words, event.getDragComponent() is losing context and is replaced by the value of event.getDropComponent().
Can anyone help fix or workaround this problem? I cannot replace the iterator with a forEach due to other requirements.
Does anyone know if this issue exists in ADF 11.1.2?
Thanks

Reordering of rows - issue with drag and drop of editable columns in table

JDeveloper: 11.1.1.6.0
ADF Faces - Drag and Drop for reordering of rows within the same af:table
I have a requirement for reordering rows in a table using drag and drop. This table is loaded using a list and I am able to programmatically do the reordering of the rows based on the events of drag and drop by manipulating the list. Reordering of rows is working fine if all the columns are read only. For all the input text and input date columns the values are not getting reordered. Anyone has any idea on what the issue may be with reordering of the rows for editable columns/rows (af:inputText and af:inputDate) in af:table. Below is what Iam doing on drop event which is a collection drop target.
public DnDAction dropCollection(DropEvent dropEvent) {
try
Object dropSite = dropEvent.getDropSite();
Transferable transferable = dropEvent.getTransferable();

Hi,
not sure its the reason but you have huge bummer in your configuration.

JSF component bindings should not be to beans in a scope larger than request to avoid stale component instances.

Programatic Generation and positioning of components using Drag and Drop

Hi,
I am relatively new to ADF and UI Designing. Im trying to generate a flowchart using drag and drop feature in ADF. This involves creation of dragging images such as start,decision .. etc from one panel to another and dynamically creating a flowchart.
Up to now i have managed to drag images from panel1 to panel2 and create them dynamically in the bean class. However im stuck at this point .. Im not able to position the draggable components on the desired position in the panelGroup. They either appear horizontally or vertically.
Is there any way to achieve this. Also is it possible to assign a dropTarget to a a target component which is created dynamically ?
Thanks in anticipation ....
Lyle

Hi Lyle,
I am too only 4 months old to adf ,i use jdeveloper 10g.
In 10g for the components to be placed at desired locations i think is somewhat possible. While you can arrange them by using spaces which causes
f:verbatim tag to appear or you can use ADF Faces Core items like Object Spacer and Object Seperator where you can set their length and width to space objects on page...

Drag and Drop to Forms

Hi OraTechies,
Can anyone give some insight to my problem.
The apps is written with Forms 6.0 and deploy in client server architecture. Soon, to be web enabled.
In production, a user constantly complain about lost data. We found out he was dragging text/data from MS-Word document and dropping to a field in a multi-record forms. When record is saved and re-queried the data is not there.
The drag and drop shows the data is being copied to the field. If the record is cleared without saving, the dragged over text is "hovering" over the field. It looks like Windows just repainted the display and nothing else.
Comments, suggestions or solutions anyone?
Cheers,
AC-NZ

Francois,
I have tried to implement this bean but I'm having problems. I've been using your
LAF package for almost 4 years now without issue. I tried the jar file from the zip
file. I also created a new project and recompiled the java code against the 10.1.2.3
frmall.jar file that matches our app server. I resigned it and it's still not working.
Maybe I'm just missing something simple. When I compile and run the form, I see
the canvas and I can change the text fields, but I don't see how I can drag and
drop items. Hopefully, you can think of something that can fix our problem. I would
love to be able to use drag and drop functionality in an upcoming application.
We're running the following versions:
App Server: 10.1.2.3
DB: 10.2.0.5
JDev: 10.1.3.3.0
Windows XP for the clients
Windows Server 2008 for the servers
Thanks,
Jason
Edit: I looked in my java console and saw that my issue was that we signed this jar file with a different certificate. I created a special config as Francois has suggested in another post and included only the DnD.jar file and it worked. However, I can't get the image or multi-line text areas to drag and drop. I'll keep poking around and see if I can figure out what's going on. The console seems to recognize when I'm dragging and dropping from all fields.

Drag and Drop objects with JavaFX properties

Has anyone tried to implement drag and drop functionality with objects containing JavaFX properties? The issue I'm running into is that the objects appear to need to be serializable, and the JavaFX properties are not serializable. I can implement Externalizable instead of Serializable, and basically serialize the values contained by the FX properties, but of course I lose any bindings by doing this (as the listeners underlying the bindings are not serialized).
The [url http://docs.oracle.com/javafx/2/api/javafx/scene/input/Clipboard.html]javadocs for Clipboard state "In addition to the common or built in types, you may put any arbitrary data onto the clipboard (assuming it is either a reference, or serializable. See more about references later)" but I don't see any further information about references (and at any rate, this doesn't really make sense since anything that's serializable would be a reference anyway). Is there a special DataFormat I can use to specify a reference in the local JVM so the reference gets passed without serialization?
I know this might not make sense without a code example; I just thought someone might have come across this closely enough to recognize the problem. I'll try to post a code example tonight...

Here's pretty much the simplest example I can come up with. I have a real-world example of needing to do this, but the object model for the real example is quite a bit more complex.
For the toy example, imagine we have a list of projects, some employees, and we want to assign each project to one or more employees. I have a Project class with a title and assignee. (In real life you can imagine other properties; due date, status, etc.) I'll keep a ListView with a bunch of unassigned projects (titles but assignees equal to null) and then a ListView for each of the employees.
To assign a project to an employee, the user should be able to drag from the "master" list view to one of the employee list views. When the project is dropped, we'll create a new project, set the assignee, and bind the title of the new project to the title of the project which was dragged. (Remember we want to be able to assign a single project to multiple employees.)
So here's the first shot:
A couple of simple model classes
Project.java
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Project {
     private final StringProperty title ;
     private final ObjectProperty<Employee> assignee ;
     public Project(String title) {
          this.title = new SimpleStringProperty(this, "title", title);
          this.assignee = new SimpleObjectProperty<Employee>(this, "assignee");
     public Project() {
          this("");
     public StringProperty titleProperty() {
          return title ;
     public String getTitle() {
          return title.get() ;
     public void setTitle(String title) {
          this.title.set(title);
     public ObjectProperty<Employee> assigneeProperty() {
          return assignee ;
     public Employee getAssignee() {
          return assignee.get();
     public void setAssignee(Employee assignee) {
          this.assignee.set(assignee);
     @Override
     public String toString() {
          String t = title.get();
          Employee emp = assignee.get();
          if (emp==null) {
               return t;
          } else {
               return String.format("%s (%s)", t, emp.getName()) ;
}Employee.java
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Employee {
     private StringProperty name ;
     public Employee(String name) {
          this.name = new SimpleStringProperty(this,"name", name);
     public StringProperty nameProperty() {
          return name ;
     public String getName() {
          return name.get();
     public void setName(String name) {
          this.name.set(name);

                    setGraphic(null);
                    setOnDragDetected(dragDetectedHandler);
}If you try to drag from the list on the left to one of the lists on the right, it will fail pretty quickly and tell you that the data need to be Serializable.
Simply adding "implements Serializable" to the Project and Employee classes doesn't work, as you find that SimpleStringProperty and SimpleObjectProperty are not Serializable. So instead I can use Externalizable:
public class Project implements Externalizable {
@Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(title.get());
          out.writeObject(assignee.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setTitle((String)in.readObject());
          setAssignee((Employee)in.readObject());
}and
public class Employee implements Externalizable {
     @Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(name.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setName((String) in.readObject());
}This makes the drag and drop work, but if you drop a project on one of the employee lists, then edit the project title in the master list, the binding is not respected. This is because deserialization creates a new SimpleStringProperty for the title, which is not the property to which the title of the new Project object is bound.
What I really want to do is to be able to drag and drop an object within the same JVM simply by passing the object by reference, rather than by serializing it. Is there a way to do this? Is there some DataFormat type I need?

Implement Drag and drop functionality in my application

I want to drag image from one UIImageView to other UIImageView.
Is there any event handle to this drag and drop functionality.
Any one have different idea to handle this. than please reply.
Any coding idea related to this?

it is possible but u have to write some advance code to handle plz mention ur Forms version and other info
Forms 10g and above possible with Java beans
Forms 6i there is a demo in forms online help ........ Search DRAG
To enable drag and drop on an item:
1     Attach the PL/SQL library DRAG.PLL, which contains the Mouse package, to your module.
2     Create a WHEN-MOUSE-DOWN trigger on each item that can be dragged. From this trigger, call the Click routine from the Mouse package.
3     Create a WHEN-MOUSE-MOVE trigger on each item that can be dragged. From this trigger, call the Move routine from the Mouse package.
4     Create a WHEN-MOUSE-UP trigger on each item that can be dragged. In this trigger, write your application specific code.Baig

Drag and Drop between two trees...

Hi ,
Please tell me how to drog and drop from two diffrient trees in a form?
is the any demo for this one .. please let me know if there..
thanks in advance
Mani

Mani,
this is not possible. Drag and drop works in client-server and even there you can't drag and drop from one tree to another because a tree is an item on its own. You could decide to build your own tree in a Java Bean and then apply drag and drop to it. Its a non trivial task though.

How do I drag and drop an action onto a task flow?

In How to pass View Object bind variable from ADF page John states that
You should also consider dragging-and-dropping the executeWithParams operation on your task flow and wiring it to occur before your page instead of putting it in the page definition of the page itself - this way it is more clear what is happening, and is the recommended approach for 11g apps. When you drag-and-drop the operation, you can use the dialog to bind the parameter to your page-flow-scoped variable by supplying the proper EL there.
How can I drag and drop the executeWithParams method onto a task flow. I am using 11.1.1.5.0 on LINUX?
I'm presuming I a need a method action in my page flow.
I have the following action defined in my page def file:
<action IterBinding="localizedCustomerHierarchyViewIterator"
id="executeQueryWithParamsForLocalizedCustomerHierarchyView"
InstanceName="BusinessRulesAMDataControl.LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RequiresUpdateModel="true"
Action="executeWithParams">
<NamedData NDName="RootEntityId"
NDValue="#{pageFlowScope.recommendationRule.customerEntityId"
NDType="java.lang.Long" NDOption="3"/>
<NamedData NDName="Language"
NDValue="#{pageFlowScope.recommendationRule.language}"
NDType="java.lang.String" NDOption="3"/>
</action>

In summary, it appears you need the following artifacts in order to initialize a view object from parameters before rendering a .jsff view that relies on that view
1) a method-call in task flow.xml file:
<method-call id="executeWithParamsLocalizedCustomerHierarchyView">
<method id="__5">#{bindings.executeWithParamsLocalizedCustomerHierarchyView.execute}</method>
<outcome id="__12">
<fixed-outcome id="__9">initializedLocalizedCustomerHierarchy</fixed-outcome>
</outcome>
</method-call>
2) a control flow rule in the task flow .xml file whose source is (1) and whose destination is the view for which you want to intiialize a view object that supports an iterator that is bound to a list, tree, etc.
3) an entry for the execute action in the databindings.cpx file
<page path="/WEB-INF/[email protected]calizedCustomerHierarchyView"
usageId="oracle_apps_br_view_RecommendationRulePFPageDef"/>
4) the page def must be defined in the databindings.cpx file
5) the page def needs to define action and iterator and list (or otherwise) that is used in UI.
<iterator id="localizedCustomerHierarchyViewIterator"
Binds="LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RangeSize="25" Refresh="never">
<sortCriteria>
<sort attribute="Level" ascending="true"/>
</sortCriteria>
</iterator>
<action IterBinding="localizedCustomerHierarchyViewIterator"
id="executeWithParamsLocalizedCustomerHierarchyView"
InstanceName="BusinessRulesAMDataControl.LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RequiresUpdateModel="true"
Action="executeWithParams">
<NamedData NDName="RootEntityId"
NDValue="#{pageFlowScope.recommendationRule.customerEntityId}"
NDType="java.lang.Long"/>
<NamedData NDName="Language"
NDValue="#{pageFlowScope.recommendationRule.language}"
NDType="java.lang.String"/>
</action>
<list ListOperMode="navigation"
IterBinding="localizedCustomerHierarchyViewIterator"
id="customerLocalizedEntityHierarchyList">
<AttrNames>
<Item Value="EntityName"/>
</AttrNames>
</list>
6) a backing bean that provides the functions to initialize the parameters for execution
The easiest way to get most of this is to drag the ExecuteWithParams from within the view in the datacontrols panel right onto the task flow diagram. The downside is that you are left with some pretty poorly named artifacts...
Did I miss anything?

Drag and drop row within same table.

Version 12.1.2
I am trying to implement drag and drop row within same table, and I am trying to follow this sample from Frank:
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/106-reorder-table-rows-1921121.pdf
But, I am getting this cast exception. The code I have in my dropEvent bean is identical to whats on the sample.
oracle.jbo.server.ViewRowImpl cannot be cast to oracle.jbo.uicli.binding.JUCtrlHierNodeBinding
ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #1

Transferable t = dropEvent.getTransferable();
DataFlavor<RowKeySet> df = DataFlavor.getDataFlavor(RowKeySet.class, "rowmove");
RowKeySet rks = t.getData(df);
Iterator iter = rks.iterator();
List draggedRowKey = (List) iter.next();

Row dragRow = draggeRowNode.getRow();
JUCtrlHierNodeBinding dropRowObject = (JUCtrlHierNodeBinding) table.getRowData(dropRowKey);
Row dropRow = dropRowObject.getRow();
//get the table's ADF JUCtrlHierBinding
CollectionModel collectionModel = (CollectionModel) table.getValue();

adfctx.addPartialTarget(table.getParent());
return DnDAction.MOVE;
It does not seem to like this line of code:
JUCtrlHierNodeBinding draggeRowNode = (JUCtrlHierNodeBinding) table.getRowData(draggedRowKey);
I would greatly appreciate any help.
Thanks.

Well there has bee a changes somehow. using 12c
table.getRowData(draggedRowKey);
returns a ViewRowImpl and no longer anything which can be convertet to JUCtrlHierNodeBinding. Anyway, the fix is easy:
    public DnDAction onDepartmentsRowDrop(DropEvent dropEvent) {
        //get the table instance. This information is later used
        //to determine the tree binding and the iterator binding
        RichTable table = (RichTable) dropEvent.getDragComponent();
        List dropRowKey = (List) dropEvent.getDropSite();
        //if no dropsite then drop area was not a data area
        if (dropRowKey == null) {
            return DnDAction.NONE;
        //The transferable is the payload that contains the dragged row's
        //row key that we use to access the dragged row handle in the ADF
        //iterator binding
        Transferable t = dropEvent.getTransferable();
        //get the row key set of the dragged row. The "rowmove" string is the
        //discriminant defined on the drag source and the collectionDrop target.
        DataFlavor<RowKeySet> df = DataFlavor.getDataFlavor(RowKeySet.class, "rowmove");
        RowKeySet rks = t.getData(df);
        Iterator iter = rks.iterator();
        //for this use case the re-order of rows is one-by-one, which means that the rowKeySet
        //should only contain a single entry. If it contains more then still we only look at a
        //singe (first) row key entry
        List draggedRowKey = (List) iter.next();
        //get access to the oracle.jbo.Row instance represneting this table row
        Object objdragg = table.getRowData(draggedRowKey);
        Row dragRow = (Row) objdragg;
        Object objdrop = table.getRowData(dropRowKey);
        Row dropRow = (Row) objdrop;
        //get the table's ADF JUCtrlHierBinding
        CollectionModel collectionModel = (CollectionModel) table.getValue();
        JUCtrlHierBinding treeBinding = (JUCtrlHierBinding) collectionModel.getWrappedData();
        //get access to the ADF iterator binding used by the table and the underlying RowSetIterator.
        //The RowSetIterator allows us to remove and re-instert the dragged row
        DCIteratorBinding departmentsIterator = treeBinding.getDCIteratorBinding();
        RowSetIterator rsi = departmentsIterator.getRowSetIterator();
        int indexOfDropRow = rsi.getRangeIndexOf(dropRow);
        //remove dragged row from collection so it can be added back
        dragRow.removeAndRetain();
        rsi.insertRowAtRangeIndex(indexOfDropRow, dragRow);
        //make row current in ADF iterator.
        departmentsIterator.setCurrentRowIndexInRange(indexOfDropRow);
        //ppr the table
        AdfFacesContext adfctx = AdfFacesContext.getCurrentInstance();
        //note that the refresh of the table didn't work when refreshing the table
        //so I needed to refresh the container component (af:panelStretchLayout).
        adfctx.addPartialTarget(table.getParent());
        return DnDAction.MOVE;
does the trick. I changed the line to
//get access to the oracle.jbo.Row instance represneting this table row
        Object objdragg = table.getRowData(draggedRowKey);
        Row dragRow = (Row) objdragg;
so you don't need the detour through the JUCtrlHierNodeBinding any longer.

ADF Drag and drop event inside the single af:treetable

Hi Experts,
I have a af:treeTable in my ADF web project and i would like to implement the drag and drop event to the same tree table for supporting my sample test project use case. Currently i am facing some issue to get the source tree node and the destination tree node of the drop and drop event inside my drop listener method. How can i get those object since i need to perform some business operation inside the listener. Please note that i am not using ADF BC4j in my project. The service layer is implemented as EJB and it's being called from the backing bean.
Looking forward some guide lines to resolve this issue from you experts.
Thank you.

It's not a perfect solution, but a work in progress that i'm currently using in my backing bean:
private RichTree navTree;
private void exitContainers() {
boolean success = false;
while (!success) {
try {
navTree.exitContainer();
} catch (Exception e) {
success = true;
private void clearDisclosedRowKeys() {
if (navTree != null && navTree.getDisclosedRowKeys() != null) {
RowKeySet rks = navTree.getDisclosedRowKeys();
Iterator rksIter = rks.iterator();
while (rksIter.hasNext()) {
exitContainers();
List<Integer> rowkey = (List<Integer>) rksIter.next();
List<Integer> newRowkey = new ArrayList<Integer>();
for (Integer row : rowkey) {
if (navTree.isRowAvailable(row)) {
navTree.setRowIndex(row);
navTree.enterContainer();
newRowkey.add(row);
} else {
// Row is no longer available
break;
if (newRowkey.size() == 0) {
rks.remove(rowkey);
} else {
rowkey.clear();
rowkey.addAll(newRowkey);
Whenever you make a 'delete' or 'move' in the tree, call clearDisclosedRowKeys(), it will remove anything that's no longer valid, so your tree won't collapse, and you won't get the error anymore.
I took out my logging and debug statements, but essentially this just gets all the rows, checks to see if they're valid, and if so creates a new RowKeySet with the valid rows in it.
Of course make sure you have the setNavTree and getNavTree accessor's created and that they're bound in your JSFF, otherwise navTree will always be null.
I haven't yet found a way to 'nicely' find out if you're at the top level container, so i'm relying on an Exception to occur to give me that information, if anyone knows a better solution please feel free to share it.
