Source Update message ignored by ADH?

I have a problem with source update messages sent to the ADH from a UPA Java application.


Source refresh messages work fine. If my app publishes a refresh with an "up" status everything is
OK.


However, sometimes my app publishes a refresh with a "down" status, followed by an update. (This is
caused by the feed that my app is publishing to TREP.)

Here is the refresh: 

<!-- rwfMajorVer="14" rwfMinorVer="0" -->

Here is the update:

                </filterList>
            </mapEntry>
        </map>
    </dataBody>
</updateMsg>

Any ideas?

    To publish service "up" status via source directory update message, provider application needs to encode the info filter entry (i.e. service name, capability) apart from the state filter entry (i.e. ServiceState, AcceptingRequests).

    Below is the sample of directory update message for service "up".

    <!-- rwfMajorVer="14" rwfMinorVer="0" -->
    <updateMsg domainType="RSSL_DMT_SOURCE" streamId="2" containerType="RSSL_DT_MAP" flags="0x80 
    (RSSL_UPMF_DO_NOT_CONFLATE)" updateType="0" dataSize="74">

                <mapEntry flags="0x0" action="RSSL_MPEA_UPDATE_ENTRY" key="257" >
                    <filterList containerType="RSSL_DT_ELEMENT_LIST" countHint="0" flags="0x0">
                      <filterEntry id="1" action="RSSL_FTEA_SET_ENTRY" flags="0x0" 
    containerType="RSSL_DT_ELEMENT_LIST">
