Can't call response.setRenderParameter from multiple event handlers

When a portlet handles two events and calls response.setRenderParameter(...) in both event-handlers, only one of calls is actually persisted and will be available during render.

Demo project to reproduce: https://github.com/olafk/multiple-events-portlet

Expected behavior: When events are sent from the SenderPortlet, they shall always be shown (both) by the ReceiverPortlet.

Erroneous behavior: Only the renderParameters for the eventhandler called last (as of System.out) are available on ReceiverPortlet.
