My solution is not pretty, but it works.
// Build a list of already expanded nodes
Set<String> expandedNodes = new HashSet<String>();
TreeNode rootNode = tree.getRootTreeNode();
for (int i = 0; i < rootNode.getChildCount(); i++){
if (rootNode.isChildOpen(i)){
expandedNodes.add(rootNode.getChildValue(i));
}
}
// Data update logic goes here
// Expand previously expanded metaspaces
for (int i = 0; i < rootNode.getChildCount(); i++){
final String nodeName = (rootNode.getChildValue(i));
if (expandedNodes.contains(nodeName)){
rootNode.setChildOpen(i, true, false);
}
}
