Apply Request Values
The processDecodes()
method is
called on the
UIViewRoot
component, causing the same method to
be called recursively on all components in the component tree with
the rendered
property set to
true
, which in turn calls the decode(
)
method on the component (or its renderer). The
decode()
method for an input component sets the
submittedValue
property for the component. For
input components with the immediate
property set
to true
, the submitted value is also converted and
validated in this phase by calling the validate()
method, causing a ValueChangeEvent
to be queued if
the validated value differs from the previous value and the local
value to be set to the converted, validated submitted value. If the
submitted value is invalid, an error message is queued and the
FacesContext
renderResponse()
method is called. For a command component, the decode(
)
method queues an ActionEvent
if the
component triggered the request.
At the end of this phase, the broadcast()
method
of the source components for all events marked to be processed in any
phase or in the Apply Request Values phase is called to notify the
event handlers. The event handlers may call the
FacesContext
renderResponse()
method, possibly after selecting a new view. If so, the processing
continues in the Render Response phase. Alternatively, an event
handler may render a response itself and call the
FacesContext
responseComplete(
)
method, in which case the request processing is
terminated.
