In Java Aktuell I wrote about Java generics and some problems with type erasure. Using JSF it is possible to re-produce a problem which occurs due to type erasure. A similar problem might appear in other situations. A developer, who doesn’t know about the special problems might get roped into endless debugging sessions.
Here it is: Generics_Type_Erasure_und_Fallstricke_in_der_Praxis-1.pdf (German)
