f:setPropertyActionListener
f:setPropertyActionListener makes it easier to do a common task in JSF application development: set a value when executing an UICommand.General Usage
To set the target UIComponent implementing ActionSource, usefor
attribute (this can be avoided if nested to another UICommand Facelet element). For specifying the bean value to be set, use target
attribute, and use value
for getting the same that will be used into target
. This Facelet will then add a new dynamic ActionListener to the parent component (or the one set in for
attribute). This ActionListener will set the target
value obtained from value
expression.
