java.util.Vector error on Domino 9, what does it mean?

I made a copy of a perfectly functioning xPages application onto a Domino 9 server, and it came up, briefly, but then started throwing errors.  I removed all the list.unshift() commands because it was having trouble with those.  Now I'm getting this, and have NO idea what it means:

java.util.Vector incompatible with javax.faces.model.Selection

I can't copy the entire stack trace, because it's on a different network.  But is there any way to tell from the stack trace WHERE this problem is occurring?  I've rebuilt the entire database, and have no errors.  I'm baffled what the problem is, or what would work on 8.5.3 and absolutely not work on 9.

You should try and install the XPages Log Reader application on your server.  This harmless app is on OpenNTF and would give you good access to error messages including the full stack trace.  To me this is a must have application on every Domino XPages server.


Again - you're not giving any code so it's very hard to really advice you.  But from the message you getting s Selection object when you're expecting a Vector.  The objects are not the same.  That's the problem.
