component.
---------------------------------------------------------------------------------------
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: Denis Morozov
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.
Actual behavior:
