Then that name of that class is really wrong
So it is a model for something that isn't uses as the real model of the
component??
Now it is just very fuzzy, and if used as normal model you get an exception.
So thats not something i like to have in the core, that we can have a model
that can't be used as a model... (normal model)

no. it's for use with something like ExternalLink which takes IModels
that cannot work with compound models yet. the code above already
works with just: new TextField("name")

the component has no model in the case where you use this class
so getModel will find the compound model via initModel().
use case for this model is ONLY:
final ExternalLink titleLink = new ExternalLink("title",
new ComponentPropertyModel("link"), new
ComponentPropertyModel(
"title"));
where more than one model is being used by a component and that component
cannot directly support compound propertymodels. the idea is that this
functionality
will be folded into PropertyModel so the use case will just be:
final ExternalLink titleLink = new ExternalLink("title",
new PropertyModel("link"), new PropertyModel(
"title"));
again, the component has no model. it's referencing the compound property
model
of the parent.
