Re: [Wicket-user] Help understanding component creation
To quote from the discussion (not the exact wording, but the basic idea):
First we introduce markup parameters (which then need to be parsed,
could become any OGNL expression), then we want conditional markup,
loops in your markup, and finally we end up with Wicket Server Pages:
JSP in another language.
Having the expressions in one place and one place only is one of
Wickets strengths: it is clear, simple and sensible.

component and initialization yourself. Thus, you would do:
MyComponent c = new MyComponent();
c.setParam1(...)
c.setXX(..
add(c);
To get a better idea, please take a look at Wicket's examples.

This is an example of what I'd like to do:

Thanks for any advice you can give!

Re: [Wicket-user] Help understanding component creation
I know the danger. I agree with the danger, and I agree with /not/
implementing it when other people are against. It is just that /I/
think it is powerful to be able to create high level components that
you can add with a single line in your java code, and then configure
the rest in your markup. And that would be the basis of combining it
with wicket:component, so that you put such components in your markup
anywhere you like to circumvent one of the drawbacks of Wicket, namely
that you have to keep your component nesting and markup nesting in
sync.
Again, potentially dangerous, but a powerful tool for the users that
can handle it. We're not especially targetting rooky programmers with
Wicket too.
