The process will be determined in runtime. For example, I have a node A, node B, and Node C. When finishing A, I will know how many B need to create. And for each B, it needs a C follow it. Is there another way to implement that? I checked workflow patterns. The MIs are working for the situation of one tasknode with multi-task instances. Thanks a lots!
