A PropertyNotFoundException is thrown when setting the listener attribute thats managed bean is set via a ui:param tag. The ace:ajax tag is set for a row select event for an ace:dataTable. The table code is being included in a main page via a ui:include. The included table page sets a ui:param name="'backingBean" thats value is the managed bean.

The ace:dataTable uses the same param and works correctly. When a row is selected the ace:ajax tag fires its listener and throws the following error:
