Loading on demand in cascade in both direction

[S C]

Hi,

(sorry for my english, french guy) ;)

I have 3 combobox who when I choose an item in ComboBox1, the ComboBox2 will be filtered according to the Combobox1. (Same thing with Combobox3 according to the Combobox2).
But I can select an item from Combobox3 without an item selected from Combobox2 (Same thing for Combobox2 without selection from Combobox1).

So, how can I load on demand combobox3 and setValue for Combobox2 and Combobox1 after I choose an item from Combobox3 ?
And after this, How can clear Combobox2 and Combobox3 if I change the value from Combobox1 (Think that comboBox2 et Combobox3 must be reload on demand) ?

Thank

Thank you Peter, with some little modification, your demo is exactly that I searched.
