dojo 1.4: difference in dijit tree html rendering

Question

Hi,

I have written an application using dojo 1.3 in which i have used the dijit tree. I am loading the tree with json data specified in the store which is in turn used by the tree model.

In the 1.3 version the tree elements pick up the id directly from the json data.However in 1.4 the tree elements have their own id which is something like dijit__treenode_4. The id's that I have specified in json are unique and im not able to understand why these are not being used anymore.

Please help me understand how this functionality has changed and how I can override the automatic id generation..

Thanks in advance,
Fell
