Flex 4 Tree Lazy Loading

Question

Hello Experts,

I have to create a tree in Flex 4, which will populate the nodes from the remote object. My tree structure would be something like this Site 1 --Eqpt 1 --Eqpt 2 Site 2 -- Eqpt x -- Eqpt y

I will be fetching the values form the Java RemoteObject using hibernate and from Site Table and eqpt table.

One easy way i can think of creating a xml from table and return to flex and assign the data provider of a tree.

Or is there any easy way which through i can add Sites first in the tree and eqpts shall be loaded at the any particular site click. I want to implement lazy loading.

Thanks in advance. Aj
