We have a flex application (swf) embedded in a war
The flex will use web services to get back some data, it
needs a parameter from http session, so we use blazeDS to get the
paramter value from session, so we also have a remote data service.
It all work fine, but from time to time after we log in to
the web, we see 'Send Fails' error, sometimes it is error getting
the parameter value from remote service, sometimes it is error
getting from web services. If i ctrl+refresh, it works again. We
suspect it is related to session or caching, but we have a large
session timeout, and we already use a query string appended to swf.
Often time it is the first time we log in if i have not hit the app
for a while.
