Initialise checked state of nodes not working when using scoped property

[amthekkel]

How does one initialise pre selected checked items when using scoped=true.
when building the tree data without scoped=true, nodes can be checked/selected using the selected/checked properties.
however, when using scoped=true, the required nodes aren't selected. Any suggestion?

For this e.g., I would expect node-1-1-1 to be pre-selected. works without scoped property set, however, i need the ability to select parent without it selecting all leaf nodes, hence looking at the scoped property.
