Hello, I have two entities

PRODUCTS
BRANDS


PRODUCTS is the entity i need to serialize

PRODUCTS attribbutes  are:
name
genericProduct (a to one relation)
brand (a to one relation)

in product java class I have this

private void writeObject(java.io.ObjectOutputStream stream) throws java.io.IOException {
NSXMLOutputStream xml_stream = (NSXMLOutputStream)stream;
xml_stream.writeObject(name(),"name");
xml_stream.writeObject(brand(),"brand");
    }

and also in the other entities:

brands:

private void writeObject(java.io.ObjectOutputStream stream) throws java.io.IOException {
NSXMLOutputStream xml_stream = (NSXMLOutputStream)stream;
xml_stream.writeObject(name(),"name");
    }




when I generate the XML following the methon in Practical WebObjects book i got XML whitout errors... but XML is missing data...

only a few products have brand.name exported
I got only an instance for brand.

(if I have more product with brand.name value set to "A" i got only an object with brand exported, others don't have brand exported)
