Well, I went off and rewrote the AjaxTree to improve it and make it work in
Tomahawk. It is a thing of beauty.
The API is very simple, just implement the AjaxTreeDataProvider interface:
public interface AjaxTreeDataProvider {
public List getRootNodes();
public List getChildNodes(String nodeString);
}
and the data is transfered via a simple VO called the AjaxTreeNode (a
javabean with 4 properties).
The nodes are rendered via as needed by Ajax calls. Multi-line node
information display is supported. Facets are used to specify the node
display.
The next thing is to add an optional toolbar in which the user can specify
what controls are available. This toolbar can be hooked into JS calls that
allow re-rooting/backing-out in the tree (a la eclipse) and refreshing.
The AjaxTree is ideal for large data sets or any situation where the entire
tree may never be viewed.
I understand not wanting to have tree1, tree2 and AjaxTree. When I built
the first version, I considered using Tree2 as a basis, but found it to be
much cleaner and simpler to build it fresh.
I strongly feel its a great addition to MyFaces. Let me know what you all
think.
