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<T>

Parameters:

object - the value returned from a method

Throws:

IOException
