It appears that we'd lost some important changes when we merged in the
2.6 code. We're basically using the changes described in
http://www.ja-sig.org/wiki/display/UPC/External+Links+to+Channels+and+tabs,
although we've added code to GuestUserPreferencesManager rather than
using the servlet mentioned in this article.
Is this something we might be able to commit to the uPortal project?
We've found it to be a locally useful feature.

Hi all,
We used to be able to successfully call channels via fname from
all layouts. We're now finding that after merging in uPortal
2.6RC1 changes channels can't be successfully instantiated by
fname from the guest layout if the channel isn't already a part of
the guest layout.
Once upon a time, we'd added a local change to make
UserLayoutManagerFactory.java read as follows:
public static IUserLayoutManager
immutableUserLayoutManager(IUserLayoutManager man) throws
PortalException {
IUserLayoutManager iulm = new
ImmutableUserLayoutManagerWrapper(man);
IUserLayoutManager ulmWrapper = new
TransientUserLayoutManagerWrapper(iulm);
return ulmWrapper;
}
Now, this wrapping the immutable user layout manager in the
transient user layout manager causes the whole guest layout to
become unavailable (as in accessing the portal as the guest user
results in a "Programming error" message, without even trying to
do anything fname-related). I'm not quite sure what's causing the
problem, but it seems like the layout it's trying to transform is
null. I've included the related stack trace below.
Does anyone have any ideas on why this feature stopped working as
of 2.6, or how we can get it working now?
