Details​

split tasks

When the split task is rendered, firstly the onBeforeTaskDisplay event is fired for the parent item (a task with render:"split"). Then "onBeforeSplitTaskDisplay" is fired for its every subtask. Returning false from "onBeforeSplitTaskDisplay" prevents a subtask from being displayed.
