How to access the parent form from a child form (JavaScript)

---

When you need to get data from the parent form of a record, you can access the parent form via:

window.top.opener.Xrm.Page

for example:

var userName = window.top.opener.Xrm.Page.getAttribute('cryer_user').getValue();

This works fine, BUT fails if the user closes the parent page and then refreshes the child page. In that scenario Internet Explorer will throw the error:

The callee (server [not server application]) is not available and disappeared; all connections are invalid. The call did not execute.

So window.top.opener.Xrm.Page is not a robust solution. Sadly I don't yet have an alternative.

These notes have been tested with Microsoft Dynamics CRM 2011, and may apply to other versions as well.
