Dynamics CRM 2011 How To
When you need to get data from the parent form of a record, you can access the parent form via:
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.
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.
