Subject [Trinidad] Setting initial expanded state in tree
Date Tue, 08 May 2007 16:35:47 GMT
I'd like to set the initial expanded state in my tree such that only the
top-level root node is expanded.  In my case, there is only one root
node and it may have one or more child nodes.


I thought the following would do it, but the second call to getKeySet()
on the PathSet object returns null:


// Collapse all nodes

CoreTree tree = getTree();



// Add the first (top-level) node to the current path 

ArrayList<String> path = new ArrayList<String>();

path.add(new String("0"));



What is wrong with this technique?


Thanks in advance,
