Jason,
thanks for your fast reply!

Quite impressive!

Hm, that means that Tapestry is in no way as flexible as e.g. AWT/Swing
where I can modify a Container on the fly as I which. I could e.g. add
Components (including Containers) to it, remove them, reorder them etc.
What is it that makes Tapestry so limited? The static component description
files?
I'd also like to have Tapestry an equivalent of a LayoutManager. In
AWT/Swing I can attach a LayoutManager to a Container which controls
the layout of the components. In Tapestry I am limited to a static layout.

I think I understand how you did it. The problem is that you don't
have a 1:1 mapping between model and view, like in Swing (again).
The latter offers you e.g. a JTree component class to *view* a tree
and a TreeModel interface for the *model*. In Tapestry I have to
fiddle around quite a lot instead.
If I am wrong (and I'd love to be wrong), please correct me! My
insight into Tapestry is still quite limited.

I am grateful that you spent some time on my question at all.
