Examples of org.openbp.core.engine.EngineException

org.openbp.core.engine.EngineException
Exception that indicates a process execution failure that is likely to be a programming error. The range is wide, from parameter binding up to missing jump targets or process inconsistencies. In general, engine exceptions are not recoverable, i. e. cannot be handled by process error mechanisms. @author Author: Heiko Erhardt
