p:Tree with checkbox preselected

[benignoms]

How can I mark a p:tree checkboxs using ManagedBean?

In previous versions I used the method setSelected(true) implemented by DefaultTreeNode class and used propagateSelectionUp / propagateSelectionDown for parents to be marked.

But in version 3.0 M3 it is not possible.

Could anyone help me?
