Hello,
I have problem with sending back empty message for some condition:
<sequence name="hotels-sequence">
<filter source="//book:getPackage/hotels" regex="true">
<then>
<send>
<endpoint>
<address
uri="http://remote.webservice.test.com:8177/"; />
</endpoint>
</send>
</then>
<else>
<xslt key="transform/empty_message.xslt">
<feature
name="http://ws.apache.org/ns/synapse/transform/feature/dom";
value="true"/>
</xslt>
<property name="RESPONSE" value="true"/>
<send />
</else>
</filter>
</sequence>
Transformation is done to have simpel XML output:
<response></response> - maybe there is better way?
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:fn="http://www.w3.org/2005/xpath-functions";
exclude-result-prefixes="fn xs xsi xsl">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/*">
<response></response>
</xsl:template>
</xsl:stylesheet>
I thought that switching property to RESPONSE, and send without
address parameters will send the message back to the aggreagator which
is next step of processing messages, but I have got this instead:

What is the solution of my problem - maybe there are some
architectural misunderstandings? I can't drop or makeFault message
because further aggregation don't work - so I think I need to send
empty message back.
Please help if you can, I'm really stuck with that :(
Best regards,
Adr
