I have a CRUD made with Primefaces, it works great except for one incident that I hardly noticed:

It works fine, but I noticed an incident, when selecting a column with ColumnToggler:

Disappears normally:

But if I change the columns to be displayed per page or I give it next in the pagination, it does this to me:

Unfold the last columns. This is my code:

How can I put the opacity attribute on an element without affecting another element that is inside? Check if there is a mysql server on the network with CMD?

I found the solution to my problem here . You have to keep the property Visibility in a ManagedBean .

   @Named(value = "basicView")
    @ViewScoped
    public class BasicView implements Serializable {

    private List<Boolean> list;

    /**
     * Creates a new instance of BasicView
     */
    public BasicView() {
        list = Arrays.asList(true, true, true, true, true, true, true, true, true, true, true, true, true, true);
    }

    public List<Boolean> getList() {
        return list;
    }

    public void setList(List<Boolean> list) {
        this.list = list;
    }

    public void onToggle(ToggleEvent e) {
        list.set((Integer) e.getData(), e.getVisibility() == Visibility.VISIBLE);
    }
    }

The button should look like this:

 <p:columnToggler datasource="asesorTable" trigger="toggler"> 
     <p:ajax event="toggle" listener="#{basicView.onToggle}"/>
 </p:columnToggler>

And in each column of the table the property is added: visible="#{basicView.list[0]}" . In my case I have 14 columns.
