Hi everyone,
I actually try to do a Celltable-Component, that can work with any
Proxy-class. So the component should work with a template class T.
(Actually it just works with a certain type of Proxy)
Inside the component, i actually got some Requests for the certain Proxy,
like delete(), persist(), findall(). These requests I want to make work
with all kinds of proxies.
Now, instead of writing:
CertainEntityRequest request = Factory.certainEntityRequest ();
Request<List<CertainEntityProxy>> findAll= request.findall(
offset, size, orderByString);
I want to have a BaseRequest, that has these services for all my proxies.
I tried to put all service-methods that I use in my component into one
base-Service, similar to this post
http://stackoverflow.com/questions/7625692/gwt-2-4-0-requestfactory-polymorphism.
persist() and remove() works well. But I dont know how to implement the
findall() / getDataPage() service.
@Entity class EntityBase {
//some methods, persist(), remove() etc
...
public List<EntityBase> getDataPage(int offset, int limit,
String orderString) {...}
}@Entity class SomeEntity extends EntityBase {...}
@Entity class SomeOtherEntity extends EntityBase
{...}...@ProxyFor(EntityBase.class) class EntityBaseProxy extends EntityProxy
{...}@ProxyFor(SomeEntity.class) class SomeEntity extends EntityBaseProxy {...}
@ProxyFor(SomeOtherEntity.class) class SomeEntity extends EntityBaseProxy {...}
...
@Service(value = EntityBase.class, locator = MyServiceLocator.class)
@ExtraTypes({ SomeEntity.class, SomeOtherEntity.class })
public interface EntityBaseRequest extends RequestContext {
InstanceRequest<EntityBaseProxy, Void> remove();
InstanceRequest<EntityBaseProxy, Long> persist();
//This doesnt work. And even if this would work, how to build the query ? I
wouldnt know the specific class, it could be SomeEntity or SomeOtherEntity....
//Thats the error: *Could not find domain method similar to
java.util.List<...EntityBaseProxy> getDataPage(intintjava.lang.String)*
*Request<List<EntityBaseProxy>> getDataPage(int offset, int limit, String
orderString)*
}
I also found this issue, I guess thats what I try to do:

Anyways, Im not sure if I even chose the right approach. Maybe there is
already an working example for this ? Or a simpler approch?

Manuel
