Popup won't open from button

Question

I have this strange thing when trying to invoke a popup when clicking on a commandButton.
I get a warning in my server output telling me he can't open a popup in a full page request.
I use the same code, in the same page in the context facet of a af:table to open the same popup and that works just fine.
Here is the facet of my table:
<f:facet name="context">
                    <af:contextInfo id="ci1">
                        <af:clientAttribute name="aid" value="#{row.id}"/>
                        <af:showPopupBehavior triggerType="click" popupId="::myPopup"/>
                    </af:contextInfo>
                  </f:facet>I use this for my commandButton
<af:commandButton id="btnNew" text="New">
            <af:clientAttribute name="aid" value="0"/>
            <af:showPopupBehavior triggerType="click" popupId="::myPopup"/>
        </af:commandButton>When i use this, jdeveloper tells me "Reference ID ::myPopup does not exist". When i remove the :: i don't get an error. When i deploy with the :: and ignore the jdeveloper error, i get the error saying opening a popup from a full-page request is not supported. I do get the same error when i remove the :: and use myPopup instead of ::myPopup so it does not make a difference.
ANybody has a clue why this is and why i can invoke the popup from my af:table and not from a commandButton?
This is the declaration of my popup:
<af:popup id="myPopup" launcherVar="source" contentDelivery="lazyUncached" eventContext="launcher">
</af:popup>Edited by: Yannick.O on 13-Apr-2010 23:49

Thanks. Setting the partialSubmit to true worked!
I believe i have seen this working without the partialSubmit.
Are their any rules when the partialSubmit should be used for the popup and when not because i'm quiet sure i have seen this working without the partialSubmit. I would just like to know why...
Why do i have to use the ::myPopup in the af:table and just myPopup to identify the popup? Why is the :: and when to use it? I'm a bit confused here.
