> Key: RF-3785
> URL: http://jira.jboss.com/jira/browse/RF-3785
> Project: RichFaces
> Issue Type: Bug
> Affects Versions: 3.2.2
> Environment: IE, FF, Opera, Safari
> Reporter: Mikhail Vitenkov
> Assigned To: Mikhail Vitenkov
> Priority: Critical
> Fix For: 3.2.2
>
>
> Step 1. Use dropListener attribute following way:
> dropListener="#{treeDndBean.onDrop}" inside rich:tree tag.
> Java bean:
> public void onDrop(DropEvent dropEvent) {
> System.out.println("onDrop occured.");
> System.out.println("DragValue: " + dropEvent.getDragValue());
> System.out.println("DropValue: " + dropEvent.getDropValue());
> // resolve drag source attributes
> UITreeNode srcNode = (dropEvent.getDraggableSource() instanceof UITreeNode) ? (UITreeNode) dropEvent.getDraggableSource() : null;
> UITree srcTree = srcNode != null ? srcNode.getUITree() : null;
> TreeRowKey dragNodeKey = (dropEvent.getDragValue() instanceof TreeRowKey) ? (TreeRowKey) dropEvent.getDragValue() : null;
> // resolve drag destination attributes
> UITreeNode destNode = (dropEvent.getSource() instanceof UITreeNode) ? (UITreeNode) dropEvent.getSource() : null;
> UITree destTree = destNode != null ? destNode.getUITree() : getTree(dropEvent);
> TreeRowKey dropNodeKey = (dropEvent.getDropValue() instanceof TreeRowKey) ? (TreeRowKey) dropEvent.getDropValue() : null;
> FacesContext context = FacesContext.getCurrentInstance();
>
> if (dropNodeKey != null) {
> // add destination node for rerender
> destTree.addRequestKey(dropNodeKey);
>
> Object state = null;
> TreeNode draggedNode = null;
> if (dragNodeKey != null) { // Drag from this or other tree
> draggedNode = srcTree.getTreeNode(dragNodeKey);
>
> TreeNode parentNode = draggedNode.getParent();
> // 1. remove node from tree
> state = srcTree.removeNode(dragNodeKey);
> // 2. add parent for rerender
> Object rowKey = srcTree.getTreeNodeRowKey(parentNode);
> srcTree.addRequestKey(rowKey);
> } else if (dropEvent.getDragValue() != null) { // Drag from some drag source
> draggedNode = new TreeNodeImpl<String>();
> draggedNode.setData(dropEvent.getDragValue().toString());
> }
>
> // generate new node id
> Object id = getNewId(destTree.getTreeNode(dropNodeKey));
> destTree.addNode(dropNodeKey, draggedNode, id, state);
> }
>
> AjaxContext ac = AjaxContext.getCurrentInstance();
> // Add destination tree to reRender
> try {
> ac.addComponentToAjaxRender(destTree);
> } catch (Exception e) {
> System.err.print(e.getMessage());
> }
>
> // Add source tree to reRender
> try {
> ac.addComponentToAjaxRender(srcTree);
> } catch (Exception e) {
> System.err.print(e.getMessage());
> }
>
> System.out.println("+++++");
> }
> Step 3. Navigate to the page contained tree rich component with D'n'D API.
> Step 4. Several times drag & drop any items from one tree to another.
