Re-read my email.

If an object or document possibly doesn't exist, you have to test 
for its existence before trying to access methods.

This assumes that self/parent exists:

   <div
   petal:condition="true:  self/parent/parent;
                    false: self/parent/parent/parent;"

This code makes no assumptions:

   <div
   petal:condition="true:  self/parent;
                    true:  self/parent/parent;
                    false: self/parent/parent/parent;"
