OmmConsumer submit PostMsg error (java EMA 3.7.0)

Jianping

Hi LSEG support,

Try to get consumer to submit PostMsg to an Interactive Provider with:
public void onRefreshMsg(RefreshMsg refreshMsg, OmmConsumerEvent event)
{
PostMsg postMsg = EmaFactory.createPostMsg();

FieldList nestedFieldList = EmaFactory.createFieldList();

nestedFieldList.add( EmaFactory.createFieldEntry().uintValue(22, 100) );

((OmmConsumer)event.closure()).submit( postMsg.payload(nestedFieldList), event.handle() );
}

But get the exception:
Exception Type='OmmInvalidUsageException', Text='Failed to submit PostMsg on item stream. Reason: ReactorReturnCodes.INVALID_USAGE. Error text: Posting not supported by provider', Error Code='-6'
at com.refinitiv.ema.access.OmmBaseImpl.ommIUExcept(OmmBaseImpl.java:1871)
at com.refinitiv.ema.access.OmmConsumerImpl.handleInvalidUsage(OmmConsumerImpl.java:649)
at com.refinitiv.ema.access.SingleItem.rsslSubmit(ItemCallbackClient.java:3158)

Hello @Jianping

As per the error message your provider application does not have the logic to respond to Posting. Please check out the EMA iProvider example with Posting to see how to do so properly.
