Is there a way to programmatically open and close nodes in a treeGrid tree that has a

[realcoder]

I have a TreeGrid with a RPC datasource. It loads fine. I can click on a node and the TreeGrid calls the datasource and loads then displays the nodes.

I want to programmatically tell the tree grid to open one of the nodes. I know the id of the node. To call open I have done this on a client only TreeGrid with no datasource and it works as expected:

 
Tree theTree = treeGrid.getData();
String id = "4";
TreeNode findNode = theTree.findById(id);
if ( findNode != null ) {
  theTree.openFolder(findNode);             
   GWT.log("Found Node by id: " + id + " Name is: " 
               + findNode.getAttribute("Name") );                              
}

But when I have a datasource by doing:
treeGrid.setDatasource(dataSource);
treeGrid.setData(tree);

Calling getData or getTree does not produce a tree that I can
call find on.

Is there a way to programmatically open and close nodes in a treeGrid tree that has a datasource?

thanks.
