Unable to get document page name for null - xpages

Question

My Xpage is redirecting the user to another page when processing is finished using the following code:
facesContext.getExternalContext().redirect("$$OpenDominoDocument.xsp?id="+unid+"&action=openDocument&framework=FA");
where "unid" is a valid documentUniqueID.
I have seen different use of this feature where the argument "&documentId=" exists.
If I use this argument the page is not loaded at all with no error anywhere.
If used with argument "id=" or open the Xpage directly: "ImportLog.xsp?id=valid unid..." I always get this error:
Unable to get document page name for null
with the following stackTrace:

Your code fails here:
/* */ public static boolean isUNID(String id)
/* */ {
/* 435 */ boolean unid = id.length() == 32;
/* 436 */ return unid;
/* */ }
So your UNID is not passed into transformer. Parameter must be "documentId", not "id".
Add more info to find why it doesn't work for you.
