jqGrid getRootNodes method is returning empty array

Question

jqGrid getRootNodes method is returning empty array, I'm using the following code to get the root nodes

var records = $trackerGrid.jqGrid("getRootNodes");
console.log(records);

any idea about this?

Answer 1

I suppose that you filled parent property of the root nodes in the wrong way. It should be parent: "null" or parent: null (see the answer).

The demo create tree grid having tree root nodes. One from the nodes is leaf. The demo shows that getRootNodes works correctly.
