Ok, I've understand the problem.

What I want:

A folderish object f has a view. This should display information from the 
children of f. The children provide this information as a snippet of HTML 
code which could be inserted directly in f's view.

f
|- a
|- b
|- c
|- d

The view of f should iterate through [a,b,c,d] and get the snippet from every 
object. The snippets should be in the same order like the objects in the 
folder. Only direct children should be called.

The problem I see with pagelets that the order is undefinied and that all 
children (recursivly) and not only direct children are called.

Or is the best way to implement a own MacroCollector for that?

Bye,

Florian
