One thing to try, in addition to Robert's suggestions, is:

   validObject(affy.batch)

And if you determine that you might have an instance restored from an
old version of R/BioC, then you might take a look at the updateObject
method which will try to update your object to the latest class
definition (works in most, but probably not all cases).
