Thx for answer as you see in second answer I have tried this, but
there is another problem with aggregation - message seems to go back,
but after receiving it seems to immediately stops the aggregation and
sends empty answer:
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope";>
   <soapenv:Body>
      <response>
         <imemptytag/>
      </response>
   </soapenv:Body>
</soapenv:Envelope>

which is aggregated response from only empty_message.xslt :
<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" omit-xml-declaration="yes" encoding="UTF-8"
indent="yes"/>
        <xsl:template match="/">
                <response><imemptytag /></response>
        </xsl:template>
</xsl:stylesheet>
but there should be also message from other endpoint //flights:
<!-- here is the endpoint we want to launch so we setup flights tag to true -->
        <sequence name="flights-sequence">
                <filter source="//book:getPackage/flights" regex="true">
                        <then>
<!-- this should be invoked -->
                                <send>
                                        <endpoint>
                                                <address 
uri="http://localhost:8166/"; />
                                        </endpoint>
                                </send>
                        </then>
                        <else>
                                <xslt key="transform/empty_message.xslt">
                                        <feature

                                </xslt>

                        <header name="To" action="remove"/>
                        <send/>
                        </else>
                </filter>
        </sequence>
<!-- we don't want hotels so we set up hotels tag to false -->
        <sequence name="hotels-sequence">
                <filter source="//book:getPackage/hotels" regex="true">
                        <then>
                                <send>
                                        <endpoint>
                                                <address 
uri="http://localhost:8177/"; />
                                        </endpoint>
                                </send>
                        </then>
                        <else>
<!-- this should be invoked -->
                                <xslt key="transform/empty_message.xslt">

                                </clone>
                        </inSequence>

                        <outSequence>
<!-- this part aggregates only one message response empty response

what's wrong? -->
                                <aggregate>
                                        <onComplete expression="//response/*">
                                                <send />
                                        </onComplete>
                                </aggregate>
                        </outSequence>
                </target>

        </proxy>
The logs for this case tells me that:
2008-12-09 14:19:47,718 [192.168.3.17-adr-37ac1b] [HttpClientWorker-4]
DEBUG AggregateMediator 1 messages of 2 collected in current
aggregation
2008-12-09 14:19:47,718 [192.168.3.17-adr-37ac1b] [HttpClientWorker-4]
DEBUG AggregateMediator End : Aggregate mediator
2008-12-09 14:19:47,718 [192.168.3.17-adr-37ac1b] [HttpClientWorker-4]
DEBUG SequenceMediator End : Sequence <anonymous>

Very strange because it nearly work for me, and very strange if I
launch both flights=true and hotels=true aggregation works fine, but
not with response made by setting RESPONSE to true (and remove To
header). Do you have any idea what happen in this case?

Best regards,
