Basic "oncomplete" question

[ksteele6]

This works just fine. It displays both alerts.

 <h:outputText value="#{MyBacking.title}" id="title">
 <h:commandButton value="Run" action="#{MyBacking.run}">

 <a4j:support
 event="onmousedown"
 reRender="title"
 onsubmit="alert('onsubmit');"
 oncomplete="alert('oncomplete');"/>

 </h:commandButton>

However I really need to use the "onclick" event and not "onmousedown" for obvious reasons. When I change the event, then only the first alert displays. The one associated with "oncomplete" never displays.

 <h:outputText value="#{MyBacking.title}" id="title">
 <h:commandButton value="Run" action="#{MyBacking.run}">

 <a4j:support
 event="onclick"
 reRender="title"
 onsubmit="alert('onsubmit');"
 oncomplete="alert('oncomplete');"/>

 </h:commandButton>

Please tell me there is something very simple that I'm missing (and what it is too). Thank you.

The second produces the duplicate request. One request is by a4j:support, the second on is by h:commandButton.
The second request is a non-Ajax one. So, the whole page is reloaded discarding the result of ajax request.

To avoid this nightmare, you can use a4j:commandButton as a natural substitute for "h:commandButton - a4j:support" combination.
If using the h:commandButton is extrimly important for you, add disableDefault='true' to a4j:support.

What the Ajax4jsf version do you use, BTW?

Sergey - Thanks for the quick reply and for the help! This forum is very helpful. I've reworked the code. Here's the working version.

 <h:outputText value="#{MyBacking.title}" id="title">
 <a4j:commandButton
 value="Run"
 action="#{MyBacking.doRun}"
 reRender="title"
 onclick="alert('onclick');"
 oncomplete="alert('oncomplete');">
 </a4j:commandButton>

Sergey - BTW I'm using Ajax4jsf v1.1.0.

Yep. Since 1.1.1, the disableDefault="true" by default.
