RequestFactory and query by example with a Proxy

[Cristian Rinaldi]

I am developing a filter to search for an entity.
The filter creates a proxy for the entity to seek, and then use this proxy with RequestFactory.
The problem is that the entity being validated do not know why.

The request is:

Request <List <EntityBaseProxy>> findByProxy (EntityBaseProxy proxy);

Their counterpart on the server is:
public List <EntityBase> findByProxy (EntityBase proxy) {
   Query query = em.get (). CreateQuery ("from EntityBase and WHERE e.namelike: arg1");
   query.setParameter ("arg1" proxy.getName ());
   List list = query.getResultList <EntityBase> ();
   return list;
}

The error I am getting is as follows:

Caused by: java.lang.RuntimeException: The call failed on the server due to aConstraintViolation atcom.google.web.bindery.requestfactory.shared.Receiver.onFailure (Receiver.java: 44) at com.google.web.bindery . requestfactory.shared.Receiver.onViolation(Receiver.java: 66)
....
....

Thanks!!!

Do you have constraints in your entity? @NotNull?

Do you use a ValueProxy?

like:

@ProxyFor(PeopleJdoFilter.class)

public interface PeopleJdoFilterProxy extends ValueProxy {

 void setSearch(List<String> search);

 List<String> getSearch();

//...

}

Thanks Brandon.

I'm using ValueProxy to send to the server.
Look at the code and the entities (EntityProxy) always validated regardless of the method is called on the server (select or persist).
Perhaps the validation should performed only in methods that require it, not always.
