Drag and Drop using iterator in ADF 11.1.1

Question

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"/>
                         <af:componentDragSource discriminant="activity"/>
                         <f:attribute name="draggedActivity" value="Drag object 1"/>
                     </af:panelGroupLayout>
                     <af:panelGroupLayout layout="horizontal" id="dropTarget1" inlineStyle="background-color:#ffff00">
                         <af:spacer height="8px"/>
                         <af:outputText value="Drop target 1"/>
                         <af:spacer width="600px"/>
                         <f:attribute name="dropTarget" value="Drop target 1"/>
                         <af:dropTarget actions="MOVE" dropListener="#{projectToolbarBean.narrativeBean.dropTest}">
                             <af:dataFlavor flavorClass="javax.faces.component.UIComponent" discriminant="activity"/>
                         </af:dropTarget>
                     </af:panelGroupLayout>
                     <af:panelGroupLayout>
                         <af:outputText value="Drag object 2"/>
                         <f:attribute name="draggedActivity" value="Drag object 2"/>
                         <af:componentDragSource discriminant="activity"/>
                     </af:panelGroupLayout>
                     <af:panelGroupLayout layout="horizontal" id="dropTarget2" inlineStyle="background-color:#ffff00">
                         <af:spacer height="8px"/>
                         <af:outputText value="Drop target 2"/>
                         <f:attribute name="dropTarget" value="Drop target 2"/>
                         <af:spacer width="600px"/>
                         <af:dropTarget actions="MOVE" dropListener="#{projectToolbarBean.narrativeBean.dropTest}">
                             <af:dataFlavor flavorClass="javax.faces.component.UIComponent" discriminant="activity"/>
                         </af:dropTarget>
                     </af:panelGroupLayout>
                     <af:panelGroupLayout>
                         <af:outputText value="Drag object 3"/>
                         <f:attribute name="draggedActivity" value="Drag object 3"/>
                         <af:componentDragSource discriminant="activity"/>
                     </af:panelGroupLayout>
                     <af:panelGroupLayout layout="horizontal" id="dropTarget3" inlineStyle="background-color:#ffff00">
                         <af:spacer height="8px"/>
                         <af:outputText value="Drop target 3"/>
                         <f:attribute name="dropTarget" value="Drop target 3"/>
                         <af:spacer width="600px"/>
                         <af:dropTarget actions="MOVE" dropListener="#{projectToolbarBean.narrativeBean.dropTest}">
                             <af:dataFlavor flavorClass="javax.faces.component.UIComponent" discriminant="activity"/>
                         </af:dropTarget>
                     </af:panelGroupLayout>
                    <af:spacer height="16px"/>
                    <af:iterator var="item" first="0" varStatus="stat" rows="0"
                              value="#{projectToolbarBean.narrativeBean.testDnD}">
                        <af:panelGroupLayout>
                            <af:outputText value="Drag object #{item}"/>
                            <af:componentDragSource discriminant="test"/>
                            <f:attribute name="draggedActivity" value="#{item}"/>
                        </af:panelGroupLayout>
                        <af:panelGroupLayout layout="horizontal" id="dropTarget1" inlineStyle="background-color:#ffff00">
                            <af:spacer height="8px"/>
                            <af:outputText value="Drop target #{item}"/>
                            <af:spacer width="600px"/>
                            <f:attribute name="dropTarget" value="#{item}"/>
                            <af:dropTarget actions="MOVE" dropListener="#{projectToolbarBean.narrativeBean.dropTest}">
                                <af:dataFlavor flavorClass="javax.faces.component.UIComponent" discriminant="test"/>
                            </af:dropTarget>
                        </af:panelGroupLayout>
                     </af:iterator>In bean:
    public Collection getTestDnD() {
        List items = new ArrayList<Integer>();
        items.add(1);
        items.add(2);
        items.add(3);
        items.add(4);
        items.add(5);
        return items;
    public DnDAction dropTest(oracle.adf.view.rich.event.DropEvent event) {
        if (event.getDragComponent() != null && DnDAction.MOVE.equals(event.getProposedAction())) {
            UIComponent dropComponent = event.getDropComponent();
            UIComponent dragComponent = event.getDragComponent();
            String dropped = "";
            String dragged = "";
            if(dropComponent.getAttributes().get("dropTarget") instanceof String){
                dropped = (String) dropComponent.getAttributes().get("dropTarget");
                dragged = (String) dragComponent.getAttributes().get("draggedActivity");
            else if(dropComponent.getAttributes().get("dropTarget") instanceof Integer){
               dropped = dropComponent.getAttributes().get("dropTarget").toString();
               dragged = dragComponent.getAttributes().get("draggedActivity").toString();
            System.out.println("The label of the dragged object is: " + dragged + ". the drop target is " + dropped);
            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

Sorry 1 correction on my earlier post.  Install iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16) NOT 12.1.0.71!
Thanks Guys!  This fixed me up.
I uninstalled
- All  Apple Packages
- Bonjour
- iTunes
- Quick Time packages
Deleted the Apple, iTunes, & Quick Times folders:
- c:\Program Files
- c:\Program Files (x86)
- C:\Program Data
- C:\Users\%profile%\AppData\Local
- C:\Users\%profile%\AppData\LocalLow
- C:\Users\%profile%\AppData\Roaming
Rebooted

Installed the newest QuickTime 7.7.6
and Bingo!  Hopefully the next iTunes release addresses the issue moving forward.
Thanks Again!
