I didn't gather that you also cannot invoke methods of persistently scoped
components via form or url.
Not directly you can't. You could invoke persistently scoped objects from
within the transitional one created when called from the form, with some
caveats.
I doubt many would consider this
Well, it seems to me that both forms are being handled by a new instance of
temp. update1 stores the value in that new instance, which is garbage
collected some time after the POST request terminates. update2 stores the
value in the prexisting instance which has been placed in the session scope,
Because you're posting to temp.cfc directly, not the temp.cfc you've loaded
into the session scope.

You couldn't, directly. You would have to post to another page, which could
send data to your session object.

When the cfm is loaded, a session scoped component is instantiated. When the

updated as expected. The odd part (to me

Essentially, you should *NOT* ever post to a cfc.
What you do is post the page to itself (or another cfm) and then pass the
arguments to the method like so:
cfset results = session.temp.myMethod(arg1,arg2...)

But I like posting to my cfc's sometimes. I just understand I am creating
one-off controller type cfcs when I do this.

Bingo. That was indeed my problem. In the docs it is written that you may only
transiently invoke component methods via form
