This problem is specific to using the RFA for data retrieval from Reuters.
When I view the KS/STATUS ric I can see that ROW80_9 is correctly populated with "BOARD_EVENT_ID: BC1"
However in the trading application logs, when I use OMMMsgUtil.getRMTESString to retrieve the value inside ROW80_9, I see "B".
I suspect the reason for this is because the OMMMsgUtils is only getting back the character/s that were updated. In this case because the previous session, "BOARD_EVENT_ID: CC1", the only change is "B" and therefore that is what the RFA is returning.
Is it possible to return the entire string properly so that our application can parse accurate data from Reuters?
If you suspect that a field may be using the partial update feature then you must first check if the update received is indeed partial. Look into method OMMDataBuffer.hasPartialUpdates(). If true, then you must traverse and process the partial updates on the field rather than simply doing OMMMsgUtil.getRMTESString(). More help about partial updates in the Javadoc and in the Developer's Guide.
By the way: I think OMMMsgUtil.getRMTESString() is your own method, right? Anyway, I can guess what it does.
