I don't know too much about the internals of Wicket, but I have opinions
on how things should work. ;-)
1) Fail gracefully: I had problems with a Panel/Form today. I got a
(Runtime) Exception as soon as it was rendered (which I couldn't
prevent). I actually wanted to show an empty form - it would illustrate
to the user that soon he/she would be able to modify some data. Sure, I
could get this working almost the way I wanted, but not without some
coding. That brings me to my second point.
2) Supply default implementations that work: Wicket developers need to
do far too much subclassing. We shouldn't have to subclass Form,
Button... simply to get something working!
Actually; why do we have to explicitly instantiate anything? Why not do
this in the html file:
<form wicket:id="form01" wicket:type"Form" wicket:action="doSomething" ... >
With Wicket I feel I'm building the GUI twice - I have to create a
hierarchy of componenets that exactly matches the (structure of the)
corresponding html file.

I actually agree we should allow nulls. We have had discussions about
this in the past, but I'm definitively in the camp that wants to
either fail right away if a value (null) is not allowed, or be
flexible about what we support.

Cant you just do new CompoundPropertyModel(new HashMap()) ?
Yes
Also check out the wicket.util.value.ValueMap helper class.
StringValue seems useful!

Hi, it's me agian...
I just discovered that this works perfectly fine:
Map tmpMap = new HashMap();
Ognl.setValue("testValue", tmpMap, new Integer(1));
Then couldn't CompoundProtertyModel have a Map as a default
object (if allowing null objects is a problem)?

An NSDictionary instance will accept *any* ognl expression.
