I confirmed that if you use the delegator.getNextSeqId() you will get an exception every time it is used with a complaint that an entity doesn't exist for the sequence you requested. It does give still generate an ID but the exception is a little concerning when you are running in a production environment. This exception probably isn't intended but is a consequence of the call to look for the entity name.
I would prefer we just outputted a warning log and not threw an exception. Another request for the sequence generator is the ability to specify the gap between the next sequence ID update. This can be configured in the entity engine but only for those IDs that have a corresponding entity. If you try to use a generic sequencer with no attached entity the default is 10 which can be low for a production environment with multiple servers. Could we add a column to the SequenceValueItem to include the next increment value?
