[Seaside] Conditionally loading/displaying a component

[Jupiter Jones]

Does the first component still display along with the results? (to allow the user to change values)

If so, you can just store the second component in an instance variable of the first component. Maybe store the results as an instance variable of the second component. The first component can collect the results and set them in the second component. That way the second component can choose if it has to display anything based on its results instance variable.

I’m sure some people will say it’s bad practise to use the session as a dumping ground for non-session related data.

There are, of course, so many ways of doing this. It’s just what makes sense for your application.

Cheers,

J
