Problem with TreeByNestingTableColumn

[Former Member]

Hi All,

I've got a problem with the NestingTree. I read a tree out of the DB and get a tree with nodes and subnodes.

So I go recursively through the tree and try to add nesting columns like this.

public void addChildren(
		IPrivateEditKkView.INodesElement parent,
		Tree tree) {
		//@@begin addCatalogEntries()
		try {
			IPrivateEditKkView.INodesNode childNode = null;
			IPrivateEditKkView.INodesElement childNodeElement = null;

			//absolute root element
			if (parent == null) {
				childNode = wdContext.nodeNodes();
				childNodeElement = null;
			} else {
				childNode = parent.nodeChild();
				childNodeElement = null;
			}

			//lese Kinder aus
			List childList = tree.getChildren();

			//füge aktuellen Knoten zum WD-Tree hinzu
			//  ... neuer Knoten
			childNodeElement = childNode.createNodesElement();

			//  ... fülle neuen Knoten
			childNodeElement.setId(Long.toString(tree.getId()));
			childNodeElement.setName(tree.getName());
			childNodeElement.setDescription(tree.getDescription());

			//  ... hänge Knoten in den Baum
			childNode.addElement(childNodeElement);

			//wenn der Elternknoten Kinder hat starte Rekursion
			if (childList.size() > 0) {
				//füge alle Kinder hinzu
				for (int i = 0; i < tree.getChildren().size(); i++) {
					addChildren(childNodeElement, (Tree) childList.get(i));
				}
			}
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}

But what I get is the header and one row only.

Does someone can help me please?

Ingo,

Looks correct.

What are settings for "hasChildren" and "isExpanded" for TreeByNestingTableColumn UI control?

P.S. Next time please replace Java single line comments (//comment) to multiline comments (/comment/).

It seems I forgot the MasterColumn. I' going to

try it again. Perhaps it will work this time.

Thanks.
