In the
preRenderView
event, the users list is retrieved using
#{userSearchBacking.retrieveUserList}
expression.
When the users list is retrieved, the
<h:dataTable>
component is populated with the users list; every row in
the data table renders a user information with the ability to remove any user using the
"Delete"
command link. The
"Delete"
command link sets the
#{userSearchBacking.selectedUser}
property with the current selected user
(
#{megaUser}
) using a property action listener and then calls the
#{userSearchBacking.deleteUser}
action method
in order to perform the delete user operation.
