[Bese-devel] UCW beginners error; it.bese.ucw::place is unbound

[Attila Lendvai]

> The slot IT.BESE.UCW::PLACE is unbound in the object #<IT.BESE.UCW-USER::MY-MODULE-CHOICE 21B457EC> (an instance of class #<IT.BESE.UCW:STANDARD-COMPONENT-CLASS IT.BESE.UCW-USER::MY-MODULE-CHOICE 21A614B4>).

i'm new, too, take it with a grain of salt...

i think you can only use the call/answer mechanism if ucw knows the
place that it needs to set when replacing your calling component with
the one being called. for that you need a container that holds your
calling component and ucw will handle the details then (maybe it's
enough if it is in a slot initialized with :component). with this you
reify the component structure for ucw, so it can replace components in
your component hierarchy when things are call-ed/answer-ed.

hope it helps,
