Yes, make everything event and/or data driven and you will not have any problems.
I do not understand what you mean by, "the response comes 2-3 itemrenderer data sets later". The result comes when it comes, you cannot predict or rely on when that is, but must use a result handler. Have the result handler update the data model, and bind the UI to the data Model.

Thanks for the responses. It would help if Adobe documented the "reuse" concept better in their ListBase class. The "reuse" concept may be better optimized for performance, but it causes issues for code that is still running after the change in data. For example, I'm using an HTTPService response to parse the data, but the response comes 2-3 itemrenderer data sets later. Could you suggest any workarounds?
