=0A=0AYou are missing a @Root annotation on the TestPref1=0Aand TestPref2 c=
lasses. The general rule is, if there=0Ais no @Root annotation then a trans=
formation is=0Aattempted as a last resort. However, typically=0Atransformat=
ions will be reserved for simple types,=0Asuch as integers, booleans, strin=
gs, dates, and so on.=0A=0ANiall=0A=0A--- Frank Beullens <f_beullens@yahoo.=
