This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

In the second paragraph, before the first example, you can read this:

If you want to be able to unserialize this in another file, an object of
class A, the definition of class A must be _prest ent in_ in that file
first.

This doesnt seem to be a one-mirror problem.


Update: the word "pres ent" is indeed fixed on the XML sources, however the word "in" still appears twice.

Heh sorry. Seems like I was a bit too fast here. Should be fixed properly this time. Thanks again.
