Re: using one component inside another

Langdon,

Not to sound stupid, but did you check to see if the variable that you store the session object is not out of scope outside of the start up function?

If you can access the Session object from the startup method through
$this->Controller->Session, it _should_ be available from within all methods

No other ideas than to ask you if you re-checked for typos etc...
