What steps will reproduce the problem?
1. create ParentObject implements IsSerializable
2. create BaseObject extends ParentObject implements IsSerializable
3. then try to deserialize BaseObject
What is the expected output? What do you see instead?
It didn't work in this case, the
com.gdevelop.gwt.syncrpc.SyncClientSerializationStreamReader try to load
incorrect class name.
What version of the product are you using? On what operating system?
syncproxy 0.2 + gwt 2.2.0
Please provide any additional information below.
None

I did some modification in SyncClientSerializationStreamReader.java, so the
line information is not correct

It's because serialization (at least in gwt2.2+) adds an opaque 'server data'
field...shades of asp.net
Anyway, a patch like the following will work:
SyncClientSerializationStreamReader.java, ~line 580
private void deserializeClass(Class<?> instanceClass, Object instance)
throws SerializationException, IllegalAccessException,
NoSuchMethodException, InvocationTargetException, ClassNotFoundException {
Set<String> clientFieldNames = serializationPolicy.getClientFieldNamesForEnhancedClass(instanceClass);
if(clientFieldNames!=null){
readString();//and toss...
}
Field[] serializableFields = SerializabilityUtil.applyFieldSerializationPolicy(instanceClass);

This seems to the same resolution suggested for Issue 36, which was just
recently resolved. It appears this patch came well before Issue 36, but since
that was resolved first, this issue is being merged into that one. In either
case, this patch as been applied and will be released as part of the 0.5
library release this weekend. Kudos to @nick.reddel for the earlier solution.
