• The ForkList Instruction is assigned a Variable Set countries that is of type List.
  • Assignment is available when displaying workflow properties and when selecting the ForkList Instruction in the editor panel.
  • The Variable Set makes use of one or more variables, the example uses the countryCode variable with type String.
  • Any number of variables can be added to a Variable Set.
• When an order is added to this workflow then it has to provide the countries Variable Set populated with country codes.
• For each element of the Variable Set, i.e. for each country code, JS7 dynamically creates a branch with the ForkList Instruction.
  • Child orders are created for each branch that runs in parallel.
  • The handling of child orders is the same as for the Fork Instruction.
• A workflow can include any number of ForkList Instructions.
  • ForkList Instructions can be nested and a branch can include e.g. Fork Instructions, Resource Lock Instructions etc.
  • More than one ForkList Instruction can use the same Variable Set.
• The Join If Failed property determines the behavior in case of failed child orders:
  • If checked then failed child orders terminate immediately and cause the parent order to adopt the FAILED state.
  • If not checked then failed child orders will be halted and allow user intervention to resume execution from an node of the child order's branch.
