or maybe add that javascript to the extended commandLink/commandButton
(through a new parameter) so that using the t:commandLink avoid the
multiple submission problem by default?...
I'll have a go at doing this, perhaps with a configurable/optional timeout
since, as a user, I've been annoyed by sites that force you to reload the
page if the first submit doesn't work.
I had a go at using the following JavaScript to prevent multiple
submissions of the same page (I used MyFaces 1.1.1. See
http://issues.apache.org/jira/browse/MYFACES-612 for the rest of the test
case.):
<html>
<head>
<script>
var formSubmitted=false;
</script>
</head>
<body>
<f:view>
<h:form onsubmit="var proceed=!formSubmitted; formSubmitted=true; return
proceed;" >
<p>
<h:commandButton value="Submit" />
</p>
<p>
<h:graphicImage value="image.png" />
</p>
</h:form>
</f:view>
</body>
</html>
...and still got IllegalStateException "Cannot forward after response has
been committed" on doing rapid multiple clicks on the commandButton. Once,
interestingly, I also got the error and blank response using just one
click after a redeployment.
I also still get the same error with my "real" application with the above
JavaScript in place.
