Ah... good to know. I'm more after the initial state. I have a component that

this particular object which way would you go? Is there way to do this with pier
functionality?
If your component is described and the attribute descriptions have
their #parameterName: set, then you can initialize these attributes
from the link: +comp|param1=value1|param2=value2+
Well, it is hard to tell what I mean. Ok, let's assume you have user object
and that object can hold an instance of another object, let's say a company object
that has an address. The editor on the web page has a select list of the available
companies and a link to create a new one. That link should be a guided tour to create a
new company with three steps. Let us further assume that a new company object has been
created and somewhat preconfigured . Now I want to be able to give this comany object to
the first page in the set to be edited further. From step1 page to step2 and so on. If
everything went well I would add the company object to the user.
I hope this is more clear what I meant.

My problem is
that PRComponent only takes componentClass and creates a new component each time. So I
need a good way to add an existing component to PRComponent or something similar. Maybe
there is another good approach how to inject state into a PRComponent component.
A new Seaside component is instantiated per embedded-link and per
session. That means, if you re-render the same link you get the same
component instance with the same state.

Furthermore, each PRComponent has a unique link that displays itself.
So if you want to reuse the same component instance throughout a
session you simply display the default #document that the PRComponent
returns.
Sounds great. I think I'm going to need this soon.
