Got it. Here's the params I needed to send with the ajax request:
var clientTree = document.getElementById("jsf_tree_64").value;
var clientState = document.getElementById("jsf_state_64").value;
var viewId = document.getElementById("jsf_viewid").value;
dojo.io.bind({
url: url,
load: function(type, data, evt){
treeTools.handleAjaxResponse(data) },
mimetype: "text/xml",
content: { "ajaxTreeRequest":
treeTools.getThisTreeId(clickedNode),
"id": id,
"name": name,
"provider":
treeTools.getNodeDataProvider(clickedNode),
"jsf_tree_64": clientTree,
"jsf_state_64":clientState,
"jsf_viewid":viewId}
});
Only took a day. Thanks for pointing me in the right direction Simon.
