Treegrid mode not working with free-jqgrid 4.9.0

I have the following treegrid working perfectly with jqGrid v4.5.2:

${"#tree").jqGrid({
url: "/tree",
datatype : "json",
colModel : [{
name: "data.id",
key: true
}, {
name: "data.name"
}],
colNames : [],
jsonReader : {
page : 1,
records : "total",
repeatitems : false,
root : "nodes",
total : 1
},
treeGrid : true,
treeGridModel : "adjacency",
tree_root_level : 1,
ExpandColumn : "data.id",
ExpandColClick : true,
treeReader : {
leaf_field : "leaf",
parent_id_field : "data.parentId"
});


The first data payload from the server is:

{
"pageIndex": 1,
"pageSize": 100
"pages": 290,
"total": 2891,
"nodes": [
{
"data": { "id": 1, "name": "Node 1", "leaf": false },
"errors": []
},
{
"data": { "id": 2, "name": "Node 2", "leaf": false },
"errors": []
}
]
}


However, this same code does not work with free-jqgrid v4.9.0. Nothing happens when a node is expanded - no JavaScript error is seen in the browser console, no request is sent to the server, no other action takes place.

Upgrading to the latest version of free-jqgrid, v4.13.4 solved the problem. The treegrid started working without any errors.
