Hi all,
I have a strange serialization problem using the following setup:
GWT 2.0.3
GXT 2.1.1
Spring 3.0.2
Hibernate 3.5.1
Gilead 1.3.2
I'd like to serialize the following class:
@Entity
@Table(name="Core_Translation")
public class Translation extends LightEntity{
@Id
private TranslationPK id;
@Column(name = "translation_value")
private String translationValue;
@ManyToOne(cascade = CascadeType.ALL, optional = true)
@JoinColumn(name="owner_id")
private Party owner;
//getters / setters
}
Now the strange thing: Under Chome, the class is never included in the
serialization policy file. Using Firefox (or IE), the class is
included about half of the time (pressing F5 to reload the page).
This yields the typical exception:
Type 'ch.wd.domain.core.translation.Translation' was not included in
the set of types which can be serialized by this SerializationPolicy
or its Class object could not be loaded. For security purposes, this
type will not be serialized.: instance =
ch.wd.domain.core.translation.translat...@1d470a6
All involved classes have default constructors and implement
serializable (via LightEntity, though I also tried with Serializable
implemented directly).
BTW: The problem does not occure if run in compiled mode. For none of
the browsers.
Any ideas?
Thanks,
Simon
