[rules-users] Drools Flow - Human Task

[Kris Verlaenen]

How about simply reusing the human task node for this.  Your process is then 
a simple sequence of 2 human task nodes.  You can use the properties of the 
human task node (like name, description, content and input/output mapping to 
add the necessary information).  Instead of using the default human task 
service for executing these tasks, you can then just write your own work 
item handler that notifies your UI when a task is created.  Your UI should 
also notify the handler when a task is completed.

Regarding continuing where you stopped last time, this happens 
automatically.  When a work item is encountered, the process will halt until 
that work item has been completed.  You should just keep your session alive, 
or if you use persistence you can simply restore the state from db as well.
