Hi Michael,
When you extend a definition, all attributes from ancestor are
inherited, and then overloaded by attributes specified in the new
definition. In your case, you overload the 'path' attribute with a new
value, disguarding the previous value.
The way to go is to have an intermediate tiles (you already have it:
plant_status_body.jsp), and a definition using this tiles. Then you use
the definition as body.
Hope this help,
Cedric
