Yes, that is possible:
combined := obj1 description , obj2 description.
Probably you need to modify the description of the referenced object,
somehow like this (untested, just quickly put together):
combined := obj1 description , (obj2 description
collect: [ :ea |
" change accessors of obj2 go trough the selector
#reference that is called on obj1 "
ea accessor: (MACascadeAccessor
accessor: (MASelectorAccessor
selector: #reference)
next: ea accessor) ].
Hope this helps,
Lukas

Yeah, this is simply because the live-callback isn't evaluated within
the context chain where the dynamic variable is defined. As a
workaround you can just reference the context-holder from within the
live-block when defining the callback. That should be probably fixed
in Seaside or maybe SmallWiki 2, I don't recall where exactly this
variable is defined.
