Try adding @SkipInterfaceValidation to the EntityBaseRequest or make sure
that all the interfaces that extends EntityBaseRequest have the getDataPage
implemented in their implementing class. I noticed a problem that the
implementing class must contain the methods that are provided. I believe
this is a problem with the request factory validation tools. To reiterate
the requestfactory validation tools do not check the parent class for the
method so I either had to add List<EntityBase> getDataPage(int offset, int
limit, String orderString){} to the implementing class. I chose to add the
@SkipInterfaceValidation so that I could allow the requestfactory to skip
validating my parent service and would get the error at runtime if it could
not find the method. RequestFactory can find the parent method when it
instantiates the service.
The problem described in the section was a problem with generics. You can
add generics to your EntityBaseRequest<T extends EntityBaseProxy> if you
wish to make the service more generic. The problem there was that the
client side code was not able to use the base service because it could not
find the client side method. Your issue is similar but different.
Hope this helps,
Chirs
