Thanks Romeo,
There was no message error when loading the TreeVirtual, the web browser
would be stopped working and i could not manipulate with the browser any
more. I have tried to re-create the TreeVirtual with list of nodes which
did not contained null value before saving to database. And the result, i
could load it successfully. When the tree has a complicate structure
(contained a lot of branches), it 's so difficult for me to re-create it.
Would you please help to give me some advice about re-creating tree
approach ? If there is another way so solve this problem, please give me
your ideas.
Thanks so much for supporting.
Thanks
Khoa Tran
