Is it possible to have an inputbox in a TreeView control?

In our project we need to have a rich tree view control with functionality such as the following:

1 - Different configurations for each node.
2 - Several checkboxes, labels, inputs per node.

For example a node may represent a task that has to be done and supervised. When the user in charge of the task completes it she checks it (checkbox 1) and writes in the input the necessary comments. When the supervisor reviews the completed task she checks the second checkbox.

Is it possible to achieve this functionality with version 2.5.a2 ?

No, AW tree does not support any composite content in tree nodes.
