using "oncomplete" in a commandButton even when onclick is empty?

In a jsf 2 project, a commandButton with id "displayDialog" is hidden. It gets triggered by a javascript function:

 document.getElementById('displayDialog').click();

The thing is, I need the click action to be performed at the stage of "oncomplete", not "onclick" (for a reason explained by @BalusC here).

I tried to do:

    <p:commandButton style="display: none" id="displayDialog" type="button" onclick="" oncomplete="cd.show();"/>

or 

    <p:commandButton style="display: none" id="displayDialog" type="button" onclick="return false;" oncomplete="cd.show();"/>

but in both cases cd.show() is not actioned. How should this be done?

(Should I just add a dummy action in the onclick attribute? If so which one?)

The oncomplete method is invoked after an ajax request, and when you say that type="button", no ajax request will be made.

That said, just remove the type="button" parameter and you don't have to implement onclick at all.

<p:commandButton style="display: none" 
                 id="displayDialog" 
                 oncomplete="cd.show();"/>

But, do you really need the button to be called from a JavaScript function? If there is another component making the first request, can't you just implement the oncomplete method of that component?

In your code, the p:commandButton has no action at all, then why do you need to wait for the action to be completed? Are you submitting a form or something?

Maybe if you explain exactly what you want to do, we can think of a better way to do it.
