How to get treedata correctly
Hi all, i am using apache tomahawk tree2 component and i get the tree item from DB. The code like:
public TreeNode getTreeData(){
List list = getMenuList();
TreeNode treeData =new TreeNodeBase("foo-folder","Inbox",false);
Iterator it = list.iterator();
HashMap menuTable =new HashMap();
while (it.hasNext()){
Eosmenu item = (Eosmenu) it.next();
String label = item.getMenuLabel();
boolean isLeaf = item.getIsLeaf() !=null
&& item.getIsLeaf().equalsIgnoreCase("Y");
int level = item.getMenuLevel();
String menuId = item.getMenuId();
String parentsID = item.getParentsId();
TreeNodeBase node =new TreeNodeBase();
if(isLeaf){
node.setType("document");
}else{
node.setType("bar-folder");
}
node.setDescription(label);
node.setLeaf(isLeaf);
menuTable.put(menuId, node);
if (level == 1){
treeData.getChildren().add(node);
}else{
TreeNodeBase pItem = (TreeNodeBase) menuTable.get(parentsID);
if (pItem !=null)
pItem.getChildren().add(node);
}
}
return treeData;
}
This works well only when the items are in the front of their chirdren. How to let it works correctly when the data in the database like :
idmenuid-menunamemenulevelparentid
1-bbb-2a
2-aaa-10
