What document provider are you using and from which editor class do you 
inherit? Please post the stack trace that shows who calls 
setDocumentContent and hence who creates the editor input.

Note that there was no official API to open external files before 3.3 
and hence it probably worked because you made some assumptions that are 
now no longer valid. Also, opening external editors became much easier 
with 3.3 as there is now API.
