How do I dynamically recreate parts of the context structure?

have an application in which I need to dynamically rebuild part of the context.

On first entering the application I build the necessary parts by calls to IWDNodeInfo.addChild(), but when I want to rebuild that part of the context there seems that there is no way for me to remove the previous nodes! The only way I have found to do this is to call IWDContext.reset() function which destroys all the non-declarative context data.

Does anyone have another idea for how to achieve this?
