Getting contents for Tree2 component
Hi guys,
I just need your advice though this is not really about the tree2 component
entirely. I just want to know how did you retrieve the data that represents
all the folders and nodes for the tree2 component. I know most likely that
data comes from a db that has a table that has a column mapping like this:
ID
NAME
PARENT_ID
Basically, I just need a guide or a tip on how to retrieve those values
effectively and load it into the TreeNodeBase object according to the order
(subfolders or nodes appearing in the right folder hierarchy)by which they
should be rendered by the tree2 component.Calling those people who had used
the tree2 component extensively, I hope you can share a piece of advice.
Thanks.

Ah, forgot to mention you need to set the node type. That is what the
tree uses to determine that facet to use. I don't know the exact
property, as I no longer have the code (we aren't working on JSF here
anymore :-( ).

Re: Getting contents for Tree2 component
Posted by kewldude <pa...@yahoo.com>.
Okay I tried to integrate this code and this is what I've come up:
List <Catalogue>list = CatalogueDAO.instance().getCatalogues(refid);
Map<String, TreeNodeBase> nodes = new HashMap<String, TreeNodeBase>();
Map<String, Set<String>> hier = new HashMap<String, Set<String>>();
TreeNodeBase rootNode = new TreeNodeBase();
for(Catalogue cat: list){
TreeNodeBase node = new TreeNodeBase();
node.setIdentifier( String.valueOf( cat.getId()));
node.setDescription(cat.getName());
int parentId = cat.getParent_id();
node.setLeaf(true);
if (parentId != 0) {//has a parent folder
Set<String> ids = hier.get(String.valueOf(parentId));
if (ids == null) {
ids = new HashSet<String>();
hier.put(String.valueOf(parentId), ids);
} else {//parent id is present in map hier
rootNode.getChildren().add(node);//add node to rootNode
}
ids.add(node.getIdentifier());//add nodeIdentifier to HashSet of ids
nodes.put(String.valueOf(parentId), node);
}
Iterator it = hier.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry)it.next();
log.debug("key:" + pairs.getKey() + " value:" +
pairs.getValue());
Set<String> ids = (Set<String>) pairs.getValue();
if (ids == null) { continue; }
TreeNodeBase parentNode = nodes.get(pairs.getKey());
parentNode.setLeaf(false);
for (String nodeId : ids) {
TreeNodeBase childNode = nodes.get(nodeId);
parentNode.getChildren().add(childNode);
}
}
}
return new TreeModelBase(rootNode);
This gives me the nasty NullPointerException, I tried to looked into the
myfaces core codes to see what I missed but to no avail...any leads on how
to get pass this error.

Something like:
ResultSet rs = ...;
Map<String, TreeNodeBase> nodes = new HashMap<String, TreeNodeBase>();
Map<String, Set<String>> hier = new HashMap<String, Set<String>>();
TreeNodeBase rootNode = new TreeNodeBase();
while (rs.next()) {
TreeNodeBase node = new TreeNodeBase();
node.setIdentifier(rs.getString(1));
node.setDescription(rs.getString(2));
String parentId = rs.getString(3);
node.setLeaf(true);
if (parentId != null) {
Set<String> ids = hier.get(parentId);
if (ids == null) {
ids = new HashSet<String>();
hier.put(parentId, ids);
} else {
rootNode.getChildren().add(node);
}
ids.add(node.getIdentifier());
nodes.put(node.getIdentifier(), node);
}
for (String parentId : hier) {
Set<String> ids = hier.get(parentId);
if (ids == null) { continue; }
TreeNodeBase parentNode = nodes.get(parentId);
parentNode.setLeaf(false);
for (String nodeId : ids) {
TreeNodeBase childNode = nodes.get(nodeId);
parentNode.getChildren().add(childNode);
}
}
return new TreeModelBase(rootNode);

something like loading the tree2 component with data from database...

What if I want to build the tree model all at once? I just need a tip/advice
on how to do the fetching from the database and load it up into the
TreeNodeBase object.

Do you want to lazy load them or build the tree model all at once?
