--------------------------------------------------------------
I will have a look at it tonight! The append issuing item is only working on
checkboxes if the checkbox itself issues the request and there the same rule
applies if it issues the request and it is sending a behavior event then it is
not appended, and that might be the culprit here because it is a "natural value
holder" unlike a button!
Either way 4606 in my opinion is a mess for little gain!

> MYFACES-4606 Causes Multiple Events To Queue
> --------------------------------------------
>
> Key: MYFACES-4679
> URL: https://issues.apache.org/jira/browse/MYFACES-4679
> Project: MyFaces Core
> Issue Type: Bug
> Reporter: Volodymyr Siedlecki
> Priority: Major
> Attachments: MYFACES-4679.zip

> Easier to demonstrate via the attached app (note that ajax tags have a blur
> event).
> 1) Deploy application with MYFACES-4606 applied.
> 2) Visit index.xhtml
> 3) Click down on the first button (don't let go)
> 4 Move the cursor elsewhere and then let the click go.
> 5) Click anywhere on the page to trigger the blur event (unfocus the button).
> 6) Repeat with the second button
> With the second button, both the listener and confirm actions to occur. Even
> though, the button wasn't actually clicked.
> In my view, only the listener event should occur, not the confirm actions.
> However, by adding the issuing element to the request, JSF thinks the button
> was clicked after all.
> In summary:
> Before 4606:
> Button 1:
> nothing called
> Button 2:
> listener called
> With 4606:
> Button 1:
> confirm called
> Button 2:
> listener called
> confirm called
> The activate action check is here:
> [https://github.com/apache/myfaces/blob/2.3.x/shared/src/main/java/org/apache/myfaces/shared/renderkit/html/HtmlButtonRendererBase.java#L65]
> The "isSubmitted" method return true for paramMap.containsKey(clientId) which
> is what the 4606 fix did (add the client id).
> *This there a way to keep the older behavior for this scenario (pre-4606)?*
> Additionally, I've seen the multiple invocations for the listener / confirm,
> but I can't pin point the problem (could be some other button click
> combination).
