Martin Grigorov commented on WICKET-3503:
-----------------------------------------
I changed locally LazyInitProxyFactory to:
- Class<?> clazz;
- try
+ final Class<?> clazz = WicketObjects.resolveClass(type);
+ if (clazz == null)
{
- clazz = Class.forName(type);
- }
- catch (ClassNotFoundException e)
- {
throw new InvalidClassException(type, "could
not resolve class [" + type +
"] when deserializing proxy");
and all tests pass.
WicketObjects.resolveClass(type) uses DefaultClassResolver under the hood and
it uses :
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (loader == null)
{
loader = DefaultClassResolver.class.getClassLoader();
}
clazz = Class.forName(classname, false, loader);
So I believe the change is for good and will solve your problem.
The only thing that stops me to commit it is that I had similar modular
application and we had no problems. The only difference was that the
application uses Guice instead of Spring.

> LazyInitProxyFactory using Class.forName(clazz) rather than

> I believe it is a problem because my base WebApplication class is in a jar

> ProjectA
> com.bf.app
> ProjectApplication extends MyBaseWebApplication
> com.bf.bean
> @Component("myBean")
> MySpringBean
> @Autowired
> private MyCommonBean;
> com.bf.page
> MyWicketPage with @SpringBean
> pom.xml depends on ProjectB
> Project B
> com.bf.app
> MyBaseWebApplication extends WebApplication
