hasChildren is for use with lazy mode.

[dt-brahim-bouaboud]

Oh okay, so if lazy is not used and hasChildren is set to true then the tree will be broken.
The document should probably be updated then because it only says

Specify hasChildren attribute in row to determine which row contains children.
