I have some config:
So, I want to invoke second query if first one doesn't return anything.
It is return null; from JdbcOutboundGateway. Further ARPMH doesn't do anything because his property is requiresReply = false;.
But I was surprised that I can't reconfigure it via xml-attribute: it is absent.
Was it done intentionally?
There are a lot gateways who might not produce reply, but it may be interest to do some recovery.
Right now only several components have 'requires-reply' attribute:
<service-activator>, <enricher> & <splitter>.
