I have a Class with a method which return a exportable class value : like this public class A { ... }

public class B { public A method1() { .... return null; } }

then when i call the method method1 in an instance of B,it says something is error. i need a help.

This should be fixed in the latest version.

which version of gwt is the exporter supporting?

I have verified that this issue is fixed, nulls are returned correctly and nulls are handled fine in method and constructors arguments.

Exporter supports latest gwt versions, see the download list.

thanks for reporting.
