Como você está fazendo para obter esta exceção?
p.s.: movido para “ferramentas etc e tal”
L
Na seguinte linha:
Decomposed decomposed = (Decomposed)activity;
Gera o erro:
java.lang.ClassCastException: activities.classes.Activity$$EnhancerByCGLIB$$10afdbdf
Coloque o stacktrace completo e o código completo do seu método.

Voce fez uma query que te retornou um monte de Activity, e nao de Decomposed. Verifique a query.
L
Seguinte o erro e nesse trecho:
if (activity instanceof Plain) {
Plain plain = (Plain)activity;
state = plain.getTheEnactionDescription().getState();
}
else { // decomposed
Decomposed decomposed = (Decomposed)activity;
}
Usando o Hibernate 2.1.7 ele entra no IF(o q é o correto). Ja usando o Hibernate 3.2 com o msm banco(e msm situação) nao acontece isso e ele vai direto pro ELSE causando o erro ja citado.
Ele não entra no IF porque esse tal de Activity não é uma instância de Plain, reveja a sua query que ela com certeza está fazendo o select no objeto errado.

Mas acho que nao é pq eu fazendo a mesma ação com o Hibernate 2.1 da certo.
