RPCRequest start/end callbacks

[vostapenko]

I'm trying to implement non-blocking loading indicators of request processing (non-blocking RPCRequest.setShowPrompt(true)). But i can't find anything to intercept RPCRequests start and end to show and hide loading icon.

Is there something useful in SmartGWT API to implement this?

Something like RPCManager.setRequestStartCallback() and RPCManager.setRequestEndCallback()

Thank you.
