work also describes my problem (submitted as "interceptor and converter
cycle").
For now I guess I'll go with case 1 at the Action cla
= tutorial.MyTypeConverter
This assumes of course that our "MyTypeConverter" class is in a package
named "tutorial".

stack and fill up the
beans myself, this would without doubt work, but I want to have it done
automatically by Struts2, if possible: hopefully just by adding the right

BTW, I am also not entirely sure that by just using Lists or Maps also the
second level elements will be mapped, those would also need some kind of
conversion indicator (ie. *-conversion.properties file), or am I wrong?
