Disabling user interface until http request is finished

Question

We are using JDeveloper 11 TP2 and we have fallowing problem. In our jspx pages (ADF Faces) in case when user clicks command button after it has been already clicked and before that first request is finished then action listener is triggered twice. We want to prevent that multiple action listener execution. How we can do that? Is there any way to maybe disable user interface until the request is finished.
Thanks in advance

We have solved our problem. Our solution is not general but in our case is good enough.
I have done it like this:
In jspx page we put javascript method.
function setToolbarButtonDisabled(ev){   
ev.getSource().setDisabled(true);
On button that should be disabled after click put Client Listener.
<af:commandToolbarButton text="#{ui_labels.newPartners}"
icon="/images/new_ena.png"
id="createPartnersBtn"
binding="#{partnersBacking.createPartnersBtn}"
actionListener="#{partnersBacking.createNewPartners}">
<af:clientListener method="setToolbarButtonDisabled"
type="click"/>
</af:commandToolbarButton>
With this after first click button is unabled .
Later when we need to enable button we do it with method
public void enableBtn(RichCommandToolbarButton btn){
btn.setDisabled(false);
AdfFacesContext.getCurrentInstance().addPartialTarget(btn);
This method is in backing been for that page and it is called in action listener for action (click on some third button ) that should enable disabled button.
