Any idea about this? I would need something similar in my application.
Just bringing this up.
You can't. Save what you need in the DB and get it from there.
out of curiosity, how are u planning to inject different session component (lets say 'comp') in the current session that has its own session components 'comp' ??
U may need to go lower than seam to achieve this -using servlets-. I don't think there is a seam API subset for communicating between seam sessions (someone correct me if i am wrong). I read once that in the code of this seam forum there is a workaround to enumerate user sessions. u may check that out.
