Vector on EMA

We are publishing a internal Yield Curve using the Yield Curve format on
a ADS via TREP Post contribution, message are accepted by the ADS and we can
retrieve then in consumer application. But the field of type vector, is always
empty on the first load of the consumer, all other fields are cached and when
we subscribe, the last data that was send is retrieved, but vector entries are
always empty until we re-send the yield curve. Is necessary some configuration
to cache this on the ADS or is an invalid usage of the Vector type?

    Hello @lmagdariaga

    I assume that you post the yield curve data to TREP cache, not to ATS via TREP, am I correct?

    Based on a your xml trace file investigation, the API always receives empty vector from TREP unless you re-post data to TREP. The issue might relate to the TREP caching. I suggest you contact the ADS support team to help you verify TREP behavior. You can contact ADS support team by submitting the query to them via Get Support of MyRefinitiv.

    Hello @lmagdariaga

    Can you replicate the issue on demand? If so please enable the EMA
    Java trace messages by setting
    <XmlTraceToStdout
    value="1"/> in
    the EmaConfig.xml file. The trace file will let us check if the Vector entry data is received by the API or not.

    Additionally, could you please share what EMA Java version and the code that you parse data? (onRefreshMsg(), etc).

    The java version is 3.2.2.0, using xml trace show us that the post
    messages was accepted, when we first subscribe to the data, we always
    receive an empty vector, but if the publish a yield curve after a consumer is
    listen, then the consumer receive the vector with all the data, but if it
    disconnect and reconnect, then the refresh message that it receive contains an
    empty vector.
