I am running the ETA tutorial4 overnight. The app exited due to an error as follows:
"Received Dictionary Response: RWFFld
Decoding Dictionary failed: Duplicate definition for fid 1.
rsslReactorDispatch() failed: Unknown return code -1 from callback.
What's the best practice to prevent this error? To clear the dictionary before decoding the response? Or just simply discard it?
I got the same problem when the application reconnected.
The code could be similar to the VAConsumer example in the Elektron SDK package.
The VAConsumer deletes the loaded dictionary when the connection is up.
We will update the ETA tutorial4 to handle this problem.
The data dictionary files are typically updated approx 4-6 week intervals, to add or amend field and enum definitions.
There is a risk that if you use an outdated dictionary to decode a payload with a new field, your application coud throw an exception.
