Class ErrorAction

java.lang.Object
  org.eaglei.repository.model.workflow.ErrorAction

All Implemented Interfaces:

WorkflowAction

public class ErrorAction
extends java.lang.Object
implements WorkflowAction

This is a marker class. Setting a WorkflowTransition's action to an instance of ErrorAction indicates there was a problem instantiating the true action -- in most cases, the reason will be recorded in the "message" member. However, when /import reads transitions with bogus actions, the true error message is lost (although it still appears in the log) because the RDF representation of the transition only remembers the class of ErrorAction, not its message.
