We could implement the checkbox set selector's form loader channel system, can you file this as a feature request? (please refer to this thread)
I am running into the same problem.
I would like to see all the tasks and sub tasks of a process. This is standard functionality of the treeview widget. However, I also would like to see the taskowner, duedate and status of the (sub)task in a grid.
In addition to these questions I wonder whether its possible (by changing the javascript file) to check if a task is a root item or a child item.
Any idea on how to realize this?
