How to get the metadata of a page(minor version) in Tridion for Context Menu Item?

Question

Workflow is enabled in the system.

There is a context menu button added to the editor which makes use of Page metadata. The Event System will update the current page path in the page metadata on when the SAVE event is triggered.

But as workflow is enabled in the system, whenever I copy a page from one SG to another SG, clicking the save button explicitly will trigger the Workflow.

Until the workflow is completed I am unable to get the modified metadata in the Context menu JS code (Event System will update the modified the current page path in metadata).

Suspected reason : Unable to fetch the metadata for minor version.

Current code :

var itemId = selection.getItem(0);
var item = $models.getItem(itemId);
var contentXml = item.getStaticXmlDocument();
var currentPath = $xml.getInnerText(contentXml, "//*[local-name()='current_path']");

How should I handle the scenario in JavaScript?

Answer 1

I am not sure it works with Javascript/CME, but when dealing with CM (back-end) code, appending -v0 to a URI retrieves the latest version of an item.

Something along the lines of

var itemId = selection.getItem(0);
itemId = itemId + "-v0";

might get you on the right path. Be careful that -v0 is only accessible to the person that owns the workflow item, so you will not always be able to read it.

An alternate approach would be to call a webservice from your code that impersonates an administrator and retrieves the info from the back-end.

Answer 2

As far as I know, to get the modified contents from an item; item should be as a major version.

To know the actual version, try this

var itemId = selection.getItem(0);
var item = $models.getItem(itemId).getInfo().Version; // Example it returns as 5.0, 5.1, 5.2

As Nuno said, this version is accessible to the person who modified.
