What happened with javax.faces.application.Action ??

Question

Can someone explain me how to perform the Action with new JSF libraries. I really do not understand why the Action class is not available in new JSF libs?
<h:command_button value="#{bundle.recalculate}"
action="#{carstore.currentModel.updatePricing}"
immediate="true" />
This is the command_button out of car demo.
The boundle.recalculate is probably an recalculate string specified in Resources.properties. But where? In WEB-INF\classes\cardemo or in WEB-INF\classes\carstore\bundles? How can I specify this in my application? I
Can anyone explain me the meaning of the new action attribute?
What is �carstore�?
What is �currentModel�?
What is �updatePricing�?
How can I compare this to the old Action-s invoke() method?
Thanks.

Hi Kim Topley,
Thank you very much. Your respond helped me a lot. I
was about to start rebuilding my code to the new JSF,
but unfortunately I did not understood to much looking
thro examples.
action="#{carstore.currentModel.updatePricing}"
The getCurrentModel() is simple returning an object
from type �CarBean� and �updatePricing� is an method
called from this object.
What is the advantage of using such an structure (2
Layers), instead of specifying the CarBean in
faces-config.xml and calling its method
�updatePricing()� One reason is that the getCurrentModel() method returns the user's current
choice of car, which can vary. The other reason is (I 'm guessing - I haven't looked at
this sample in any detail) that the cars are all created in the application model
and therefore do not need to be instantiated as required by the managed beans
feature.
or in that case it will be
"getUpdatePricing()" directly? (1 Layer)In a method binding, the last part of the name is always the full method name.
The mutation to "getXXX", "isXXX" or "setXXX" happens only for a value binding.

Is there any other limitation regarding
updatePricing() method except that it must have no
arguments and it must return a String?Not that I am aware of.

I must say the new feature <f:loadBoundle �> is an
great feature, and I am very glad to have something
like this.
Do you know if bundle is being loaded for every
request new, or if let say English bundle is loaded
once, it stays in application request for the rest of
time?It is loaded for each request. However, this is not as bad as it seems,
because the ResourceBundle class keeps a cache, so it is likely that
most loads will be satisfied from the cache with almost no overhead.

PS: I am very glad to see some movements here in JSF
forum. Last few weeks we have not seen to many
discussion.
