       EntityWithObjectReference.java



Everything is built using maven, so files end up where they should

be.



Original base entity class I want to emulate:

package dao;

public class EntityWithObjectReference {

   public Object objReference;

   private String text;

   public String getText() {

       return text;

   }

   public void setText(String text) {

       this.text = text;

   }

}



Emulated base entity class (implements serializable, Object ref

removed):



package dao;

import java.io.Serializable;

public class EntityWithObjectReference implements Serializable {

   private String text;

   public String getText() {

       return text;

   }

   public void setText(String text) {

       this.text = text;

   }

}



The class I actually use in both client and server side:



package dao;

import java.io.Serializable;

public class ExtendedEntity extends EntityWithObjectReference

implements Serializable {

   private String name;



   public String getName() {

       return name;

   }



   public void setName(String name) {

       this.name = name;

   }

}



There's also a EntityWithObjectReference_CustomFieldSerializer.java,

which simply ignores the Object reference for now:



package dao;

import com.google.gwt.user.client.rpc.*;

public class EntityWithObjectReference_CustomFieldSerializer {

   public static void serialize(SerializationStreamWriter writer,

EntityWithObjectReference entity) throws SerializationException {

       writer.writeString(entity.getText());

   }

   public static void deserialize(SerializationStreamReader reader,

EntityWithObjectReference entity) throws SerializationException {

       entity.setText( reader.readString());

   }

}



Now, if I just leave the source element empty (it should include all

the java files in the package), everything works fine, serialization

works as expected, and custom serializer is being called.



serialization.gwt.xml:

<module>

   <inherits name="com.google.gwt.core.Core"/>

   <source path="dao">

       <!--include name="ExtendedEntity.java"/-->

       <!--include name="EntityWithObjectReference.java"/-->

   </source>

   <super-source path="substituted"/>

</module>



***When I try to uncomment the two lines*** that explicitly include

the specific java files (I need that because the original library I

want to emulate has a number of additional files in the source

packages that gwt doesn't ever need to know about), there's a problem

- GWT keeps complaining that 'This application is out of date, please

click the refresh button on your browser'. The server response is the

same in both cases:



//OK[3,2,1,["dao.ExtendedEntity/1266011518","xxx","evil entity"],0,5]



But GWT generated javascript expects a different checksum in this

case, and an exception is raised when deserializing the data. Any

ideas why this is happening? Bug, feature, a bit of both? I'd be more

than happy to supply the code to verify this behavior, if anyone can

help me sort this out.
