When I click a command button, and then hit the browser back button to the
form and click it again, it submits a second time without throwing the proper exception...
Even stranger, the
form id itself is DIFFERENT when I come back, which implies it has regenerated a "valid"
form id at some point.
Here's the relevant code: Any ideas?
<h:form id="accountActivationForm">
<s:token/>
<a4j:commandButton id="cancelActivateAccountButton"
action="#{controller[cancelAction]}"
image="/images/button-Cancel-gray.gif"
reRender="#{reRenderList}"
oncomplete="#{onCancelComplete}" />
 
<a4j:commandButton id="activateAccountButton"
action="#{controller[agreeAction]}"
image="/images/button-i-agree-continue.gif"
styleClass="activate-account-button"
reRender="#{reRenderList}"
oncomplete="#{onActivationComplete}"/>
</h:form>
Clarifications:
I inherited this, so I'm trying to change it as little as possible. (It's used in a couple places.)
Each action returns a view, not null. I have confirmed this by stepping through line-by-line.
The reRenderList is empty in my current test-case.
onActivationComplete is also empty.
I'm going to be going template-by-template to see if someone made it with nested forms, because my coworkers have had unrelated problems due to that, so it couldn't hurt to eliminate that as a possible problem.
