Transitions as wait states

A wait condition indicates wether a transition is to be taken synchronously or wether the transition will behave as a wait state.

Transitions that are wait states can occur when an analyst has an actual state (e.g. 'making loss') and a desired state (e.g. 'making profit') and models a transition between those states. In that case the transition might take a long time and hence it results into a wait state for the system.

If the wait condition is null or if it returns false, then the transition will be taking synchronously. Otherwise the transition will behave as a wait state and wait for a signal on the execution.

Transitions as wait states has every thing to do with matching the process graph to transactions on the server. If the transition is taken in one (the current) transaction, then the async condition should be empty or evaluate to false. If the arrival of the execution in the destination activity should occur in a separate execution
