How to update after an action listener is finished

Question

I have created a list of elements with two buttons. The first is "accept", the other is "decline". Whichever button I press, I want it to be removed from my datatable and have my list updated without the removed element. My problem is that my list cannot be updated quickly enough, so I have to wait one second.

<p:commandButton value="Accept" update="mydatatable"
                            <f:setPropertyActionListener value="#{mymessage}"
                                target="#{myView.accept}" />
                        </p:commandButton>

My view. accept

TimeUnit.SECONDS.sleep(1);
                FacesContext.getCurrentInstance().addMessage(null,
                        new FacesMessage(FacesMessage.SEVERITY_INFO, "element removed", ""));

What I want to do: execute the update once MyView.accept() is completely finished. I tried to change update by oncomplete/on success but I didn't get any satisfying result. I m looking for something like oncomplete = update="mydatatable"

How could I do that ?

And how does this remove the button from the datatable? – Kukeltje Mar 19 '18 at 17:06
The buttons are displayed in every row of the datatable. When the list is updated, the element is not part of the list anymore and its buttons are gone too. – Jean Mar 19 '18 at 17:13
But then there is no need to `update="@this"`.... Unless you have some other problem for which this is a workaround... (http://www.xyproblem.info) – Kukeltje Mar 19 '18 at 17:26
