Passing parameter in JSF

In JSF, there are several ways to pass data from the client (browser) to the server.

1. value binding
Which is the default in JSF
eg

2. f:param
eg,

to retrieve the value in managedBean, write the following codes.

3. f:setPropertyActionListener

eg,

in managedBean,

with setPropertyActionListener, setter of the property is invoked before action method (myAction), thus we can get the property value in the action method.
the disadvantage of f:setPropertyActionListener, it passed in value must be String type.

4. a4j:param (Richfaces 4 ONLY)
eg,

in managedBean

the usage of a4j:param is similar with f:setPropertyActionListener. But the advantage of a4j:param is, value other than String still can be passed.

5. JSF2 action 
eg,

in managedBean,
