oData for treetable - SAPUI5

Hi all,

I am trying to use treetable in a SAPUI5 based project. It is working fine with local data (very much similar to example at this link: http://localhost:8080/demokit/#content/Controls/Complex/TreeTable.html). But now we have to build oData Service to generate similar data, and then bind it to the treetable.

So how do i design oData service and bind it to treetable for this kind of requirement? Because, here we don't need just a set of rows (which can be accomplished by using a entity set), instead we need parent-child relationship between rows..!!

So, any suggestions/examples/code snippets/links would be great?

Thanks in advance,

Vinay C
