I've got it.

You use a lazy initialization pattern for the 'container' instance
variable, which means it ends up getting created during the
#renderContentOn: method.

One of the inherent assumptions Seaside makes is that the render methods
are functional - they have no side effects, or no important ones.  This
violates that assumption (which I should clearly make more formal), and
that causes some wierd problems.

If you create the container in the #initialize method instead, everything
works.
