Users can use undo with “Ctrl-z” and redo with “Ctrl-y”.
The copy-paste functionality comes with the following boundary conditions:
Users can select one or more tasks to be copied and pasted.
Copy-paste is only possible inside of a Workflow Designer’s window. It is not possible to paste to another window than copied from.
The id of pasted tasks differ from the original ones.
Any customized information (e.g. service task's name and version) are available in pasted tasks.
Workflow parameters and any automatic generation of input/output (e.g. sub process) are automatically updated after paste.
Undo and redo is supported (e.g. undo will undo the paste, and anything that's generated by paste).
