3. [[!getField? &field=`longtitle`]] -> current resource longtitle 

4. [[!getField? &field=`InvalidField`]] -> No Result!

5. [[!getField? &id=`16`]]  -> id 16 resource pagetitle 

6. [[!getField? &id=`16` &field=`longtitle`]]   -> id 16 resource longtitle 

7. [[!getField? &id=`16` &field=`TestTv`]]  -> id 16 resource TestTv 

8. [[!getField? &id=`16` &field=`InvalidField`]] -> No Result!

 * OPTIONS
 * id - The resource ID
