When using rich:fileUpload with flash="false" and the file to be uploaded is e.g. 20 MB, then I get always this error:
23:08:17,796 WARN [SeamPhaseListener] uncaught exception, passing to exception handler
org.jboss.seam.ConcurrentRequestTimeoutException: Concurrent call to conversation
at org.jboss.seam.core.Manager.restoreAndLockConversation(Manager.java:641)
at org.jboss.seam.core.Manager.restoreConversation(Manager.java:603)
When using rich:fileUpload with flash="true", then no error occurs and the file is successfully uploaded. How can I use rich:fileUpload with flash="false" and avoid this error?
According to
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=151672, I want to try the a4j:queue:
<h:form id="myForm">
<a4j:queue requestDelay="1000" ignoreDupResponce="true"/>
<a4j:outputPanel>
<rich:fileUpload id="myFileUpload" allowFlash="false" .. >
</rich:fileUpload>
</a4j:outputPanel>
</h:form>
But this does not work. I get the always the ConcurrentRequestTimeoutException. What should I do?
