TYPE_RESOLVER in ca.odell.glazedlists.impl.beans.BeanProperty

[engintekin]

Hi,

We are currently using GlazedLists v 1.7 and like to upgrade to version 1.8, but we couldn't solve a problem
that it's saying "Expected ParameterizedType but found TypeVariable".

We modified a line in BeanProperty class

currentClass = TYPE_RESOLVER.getReturnType(currentClass, partGetter);
to
currentClass = partGetter.getReturnType();

now it seems there is no problem. Is there a problem with this?

Thank you

Nope, but it suggests that I have a bug in TypeResolver. 

I suspect this is happening with a method whose return type is parameterized. Can you paste the signature of the offending getter in an email so that we can write a test? You'll be able to figure out which one by printing 'partGetter' before the call to getReturnType. Whichever getter is printed immediately before the stacktrace is our candidate.

Thanks.

Hi,

class A<T extends B> {

     public T getB(){}
}

The list is filled with "new A()", I think it's working if the list was filled with "new A<B>()"
