Hi Ruslan,
I create a temp field like this
   fld = 
myDatabase.myReferences.createVarCharField("authorEditorSortMethod", 
2000, EVFlag.fNone, "IFNULL(authors, IFNULL(editors,title))")
and dispose of it later with
   myDatabase.myReferences.deleteField(fld)
With b33 I get an error that deleteField does not exist.
Is .dropField the new equivalent?
Thanks,
Jon
