Re: meta data merging

Hi Geert,

For example I have

         Foo.class
         FooMetaData.class

I'm sending a list of Foo objects but in the resultant serialization
there is FooMetaData objects aswell:

//
OK[7,4,0,0,3,0,0,2,6,3,0,0,3,0,0,2,5,2,0,0,3,0,0,2,4,1,0,0,3,0,0,2,4,1,
["java.util.ArrayList/3821976829"
,"headman.client.model.Foo/
1687815141","headman.client.model.FooMetaData/
3712087070","a","b","c","d"
],0,3]

if there were no FooMetaData in the package the result of the
serialization would be like

//OK[6,4,2,5,3,2,4,2,2,3,1,2,4,1,["java.util.ArrayList/
3821976829","headman.client.model.Foo/3741164013"
,"a","b","c","d"],0,3]


The problem occurs at the client side when client tries to deserialize
because it doesn't expect a FooMetaData.

as you said adding transient should solve the problem


    "Serializable User-defined Classes
    ..........
       2. all non-final, non-transient instance fields are themselves
serializable, and
    ..........

    The transient keyword is honored, so values in transient fields
are not exchanged during RPCs. Fields that are declared final are also
not     exchanged during RPCs, so they should generally be marked
transient as well." (http://code.google.com/webtoolkit/documentation/
com.google.gwt.doc.DeveloperGuide.RemoteProcedureCalls.html#SerializableTypes)

for your refrence:

public class Foo implements IsSerializable{
        public String name;
        public int age;
        public Foo(){}
        public Foo(String name, int age){
                this.name = name;
                this.age = age;
        }
}

public class _FooMetaData extends
                MetaData<ConstrainedBean, ConstrainedProperty> implements
                IsSerializable {
}

the serialized list object:
        List l = new ArrayList();
        l.add(new Foo("a",1));
        l.add(new Foo("b",2));
        l.add(new Foo("c",3));
        l.add(new Foo("d",4));
