      Description

      If we have an empty zone like this:
      <t:zone t:id="myZone" />

      zone.getBody() fails to update the zone in an event handler with the following exception:

      org.apache.tapestry5.ioc.util.UnknownValueException
      A component event handler method returned the value <PlaceholderBlock>. Return type org.apache.tapestry5.internal.structure.ComponentPageElementImpl$PlaceholderBlock can not be handled.

      This is because ComponentPageElementImpl.PlaceholderBlock does not implement RenderCommand.

      A patch is provided with a test that fails.

      I would highly appreciate it if a commiter applies it to the 5.4. branch and to the 5.3. branch.

      Cheers,
