You should rather talk about the "evaluation order of the attributes". It's "ref > field-ref > variable-ref", "default-ref" is used when no ref is present and that field-ref nor variable-ref points to something useful. "else-ref" contains a sequence of participant that are used in case of failure of communication with ref/field-ref/variable-ref. As soon as a participant in else-ref gets the workitem (dispatch successful), the participant expression is considered as 'applied'. > Am I all right that the attribute forget is set to true then the execution > is like an and split, so only the first participant of the execution list is > considered and the timeout variable is useless in this case?
