Create a class to use for the row, give it a boolean field for the checkbox to bind to.

Now you need to create a list of these and expose them to the front end.

There are two ways, expose it through a factory method, @Unwrap or just have it as a List property a seam component. Don't just have the list as a property though, it will work but the performance is lousy because the seam interceptors will get called too many times.

Now in you dataTable put in a column with a h:selectBooleanCheckbox and bind it to the boolean property on your row.

                   rendered="#{not empty processNodesList.resultList}" rowClasses="#{tableLnF.getRowSettings(skinBean.skin)}" 
                               headerClass="#{tableLnF.getHeaderSettings(skinBean.skin)}"
