DataLoaded event not firing on new instance of Custom Object workspace.
Content
I've created a Workspace Ribbon Add-In, which is placed on the Incident ribbon. When pressed, it will launch a new Custom Object workspace (CO$Escalation). This functionality works just fine, the new workspace instance launches without an issue.
My next step is to subscribe to the DataLoaded event, in order to try and populate a field using data from the Incident workspace (namely the Incident ID). My issue is that the DataLoaded event doesn't seem to be firing when the new workspace instance (CO$Escalation) is loaded.
Any thoughts as to what I may be missing here?
