The call chain looks like:
<your code> ->
Both of the tool methods return the result of calling the action. In
cases where the ObjectMoved exception is raised, the exception has the
"new" object wrappers available, but the tool consumes that part of the
information (as you note).

Not really; but the tool doesn't expect that you will need reindex the
object (it already does that in the new location).
Here are a couple of alternate strategies:
- You could modify the workflow action's result (which is coming from
the code which actually raises the ObjectMoved exception) to include
the newly-wrapped object in the result (e.g., as a tuple with the
- You could move the code in '__do_something_with_my_object__' into an
"after" script of the workflow, where it would be passed the object
in its new wrappers.
- You could use the CMFUID tools, and find the object in its new
location after running the workflow transition using its UID.
Hope that helps,
