PrimeFaces table selection, For two approve and disapprove columns - jsf

Question

I have developed an approval screen(for user creation). There I have included two states which were approval and disapproval. Currently it takes the reading only as approval and it doesn't check disapproval. approval process is working fine for me. but I want to have disapproval part as well.
I want to improve my code to take separate readings for above mentioned two different states.
How can I get the approval and disapproval objects to two separate List??? Cant find example for two selection ways in primeface.
I want to know how do i get a column selection as approve and disapprove.
I have the following screen
I have the following datatable
<p:dataTable id="userApprovals" var="user" value="#{userApprovalBean.userApprovals}"
selection="#{userApprovalBean.selectedUser}"
widgetVar="usersTable"
rowKey="#{user.username}"

Answer 1

You can use p:selectBooleanCheckbox in approval and disapproval column with unique value objects and can easily get the approval and disapproval selection list using If condition
