As mentioned in documentation.. TASK NODE A task node represents one or more tasks that are to be performed by humans. So when execution arrives in a task node, task instances will be created in the task lists of the workflow participants. After that, the node will behave as a wait state. So when the users perform their task, the task completion will trigger the resuming of the execution. In other words, that leads to a new signal being called on the token. NODE The type node serves the situation where you want to write your own code in a node. The nodetype node expects one subelement action. The action is executed when the execution arrives in the node. The code you write in the actionhandler can do anything you want but it is also responsible for propagating the execution. But confusion is that, where to use task node , and where a node.. Coz in both the case required acton is being written inside a handler class....
