Jsf setpropertyactionlistener example

Jsf setpropertyactionlistener example

Jsf ‘<f:setPropertyActionListener>’ tag creates a special action listener and registers with the associated action. It sets value specified by ‘value’ attribute to ‘target’ attribute.It is generally used in datatable to get the record selected by the user.

Attribute          Value expression
value                store the value of target attribute
target               defines the destination of value attribute

In the below example, the ‘stud’ property is set to student property of the studentBean. This will take place before editStudent method is executed.

<h:commandLink value=”Edit” action=”#{studentBean.editStudent}”>
<f:setPropertyActionListener value=”#{stud}” target=”#{studentBean.student}” />


In the below datatable, the f:setPropertyActionListener of the h:commandLink sets the ‘stud’ object on which user clicked to ‘studentBean.student’.
