      Description copied from interface: `ComponentEventResultProcessor`
      For a given, non-null return value from a component event method, construct and send a response.

      Starting in release 5.4, it is recommended that for any response that involves Tapestry pages or components, the implementation should create an `IOOperation` to do the rendering, and add the operation to the `Request` as attribute `TapestryConstants.RESPONSE_RENDERER`. This avoids a number of issues related to the `Environment`.
      Specified by:
        `processResultValue` in interface `ComponentEventResultProcessor<Class>`
      Parameters:
        `value` - the value returned from a method
      Throws:
        `IOException`
