thx,
once more i wnat to know what are the most important / generally functions
in shale, that used in modell objects:
1. the facesmessage - maybe generating some stuff
2. getbean - maybe get acces to managed beans - change them etc
...
...
shale is a framework built on the base to have features, which can be
replaced and als which don't have to used - in fact a user if he is only a
jsf fan he don't use shale features - but he can...
clay is genial... and other parts too - so on should
would it possible to use mybe shale clay on every other jsf framework or
references it to myfaces sources?
what more...

If you look at the source code for AbstractViewController itself, you will
see that it extends AbstractFaceBean, which in turn contains the defiition
for getBean(). Then, if you look at that method, you will see that it
simply uses standard features of the JavaServer Faces API that let you
interact with the standard JSF "Variable Resolver" -- the part of JSF that
actually implements managed beans:
protected Object getBean(String name) {
FacesContext context = getFacesContext(); //
FacesContext.getCurrentInstance()
return context.getApplication().getVariableResolver().
resolveVariable(context, name);
}
A similar convenience method lets you evaluate any value binding
expression
(such as "#{foo.bar}") from within an application, again using standard
JSF
APIs:
protected Object getValue(String expr) {
ValueBinding vb = getApplication().createValueBinding(expr);
return vb.getValue(getFacesContext());
}
i "googled" and found a relationalship to spring - so i looked on apache

No, this particular feature was inspired by similar features in the
application model that Sun Java Studio Creator uses for the applications
it
builds. The part of Shale most directly influenced by Spring is the
DIalog
feature, which has conceptual similarities to Spring Web Flow -- in
particular, the idea of modelling a dialog as a state machine with action
states and view states (among others).
