Sub class a dao implementation

[GoogleCodeExporter]

First, Great job, we use your generic dao in our project and it's very handy !

What steps will reproduce the problem?
1. create an implementation of GenericDAOImpl<ModelClass, IdClass> named
ParentDao 
2. extend ParentDao in ChildDao
3. new ChildDao();

What is the expected output? What do you see instead?
Constructor threw exception; nested exception is
java.lang.ClassCastException: java.lang.Class cannot be cast to
java.lang.reflect.ParameterizedType

What version of the product are you using? On what operating system?
Java 6 64 bits, ubuntu 8.10, but it's irrelevant.
Present in r590.

Please provide any additional information below.
It's a common issue with Generics. This blog entry shows a solution :

Having the choice between an empty constructor (which would infer the
persistent class' type from the generic argument) and a contructor that
takes the persistent class as an argument would be a great solution if you
don't want to implement the whole solution :)

Thanks a lot !

Thanks for reporting and for the solution! I remember we had this problem back 
in the 
early stages but didn't get around to fixing it at the time.

I'll get this fix into the next release (0.5.1).
