This is not quite true, the updateActionListener sets the parameters bevore the invocation of the action this is due to jfs lifecycle where the apply request values is before the action, which phase depends on your immediate value:
I quote the original docs here: >Both the fetching of "value" and the updating of "property" occur in >the invoke-application phase unless "immediate" is set on the >ActionSource component in which case they both occur in the >apply-request-values phase. The update is guaranteed to occur before >the invocation of the method specified by attribute "action" on the >ActionSource (because all actionListeners are executed before the >action attribute). so you basically already have the params available before you go into the action. so you do not have params per se in an action but you can push params into your bean bevore invoking the action.
