It turns out this is relatively easy to do, so > I'm planning to submit a PR for this feature soon. > > The GUI will have one window for every fragment instance (the master fragment > instance and then one for each ESP fragment instance). This window will allow > to step one subtask (work method invocation, see class ExSubtask) at a time, > or it will allow to set breakpoints at specific subtasks, or one can resume > the instance without the GUI. I'm also adding a very primitive queue display, > but that will need more work, in the first version it won't be possible to > look at the data in the executor queues. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
