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?
The shale-clay library itself depends on shale-core, but that does not
mean your application needs to use any other Shale features if you do
not wish to. There is no reason to reference sources from the MyFaces
JSF implementation (or the reference implementation), because Shale
utilizes only the standard extension APIs that JSF provides.
