jsNode is the preferred object to access node properties and aspects by using JavaScript on the browser.
When dealing with DataTable records, record.jsNode should be available.
Note: It is the responsibility of any code that updates DataTable
records to also ensure the jsNode property is updated (usually within
the AJAX success callback).
To create a jsNode instance, use:
jsNode = new Alfresco.util.Node(p_node)
where p_node can either be a JavaScript object or JSON string. In either case, it should be in the format returned by the doclist-v2 data web scripts.
