[Oryx-users] ClassCastException when saving templates in repository

[Jochen H. <joc...@db...>]

ClassCastException were thrown when i added a template rule to the repo=
sitory. The problem occured in CloneService.clone(Rule), line 53. The R=
ule's body is cast to Prerequisite, while the type is FactImpl (impleme=
ntation of Prerequisite's super class Fact).

This patch fixed the problem for me. It does not automatically handle n=
ew subclasses of Fact, this could be achieved by moving the clone()s to=
 the Fact/Prerequisite classes.

<                       body.add(clone((Prerequisite) it.next()));

>                               body.add(clone((Fact) o));
>                       } else {
>                               throw new RuntimeException("Unknown Fac=
t subclass " + o.getClass());
>                       }
