How to link to a page from inside an embedded component

[NorbertHartl]

Hi,

I have a component embedded on a page. Inside this component
I want to create links to pages inside my pier kernel.

If I do such a component what would be the best base class?
(WAComponent?).

How can I create a link to another page by specifying the
path? Or something else?

thanks,

Norbert

If you use URLs you lose the current session and possibly state.

The right way to do this, is to use objects, e.g.

     html anchor
         goto: newContext;
         with: 'A Pier Link'

where 'newContext' is the description of where you want to go. Create
this new context object from the current one like so:

     newContext := self context structure: aStructure

where 'aStructure' is the page you want to go to and 'newContext' is a
temporary variable. Instead of using #structure:, it is also possible
to use #structure:command: or #structure:view: to specify a different
command or view.

Cheers,
Lukas

Well, I should try to be more clear when asking :) I don't want to loose
the session in between. I want to do it exactly like you wrote here. My
question was towards looking up/finding the structures. It was meant as
"What is the easiest way to find a structure when I now a path?". The
idea (so far) is that I know some of the structure of the site. I want
to do my own component and then I want to link /a/b/c. So I need a way
to lookup /a/b/c as a structure to able to link to it. I imagine the
answer could be PRPathLookup but are there other ways to do?

thanks,

Norbert

There is #lookupPath: and friends defined in PRStructure. This allows
you to lookup structures relative to the receiver. If the path starts
with a slash it is always relative to the root. Internally these
methods use PRPathLookup.

That sounds good. Is it better the just request PRCurrentContext or
is it better the take a pier class as base class for my component?

That doesn't really matter, both will work WAComponent and PRWidget.
For a Pier specific component PRWidget is probably more appropriate.
