Valy, I would add some trace statements into your
ActionScript code around these lines:
addr.individual = ModelLocator._individual; // _individual gets loaded when app
is initializes.
ModelLocator._individual.physicalAddresses.push(addr);
ModelLocator._individual.physicalAddresses.push(addr);
I
would double check that the individual on the ModelLocator is populated as
expected before sending it over the wire.
It
doesn't appear to be related to this case based on the code you've provided, but
note that objects are deserialized on the client by the Flash player in a
special order - an object's fields are set before the constructor is
invoked (so that you can have access to them in the constructor) so one has to
be careful not to re-initialize them on constructing a new instance. Also be
careful of relying on references on the client when round tripping instances as
while it sounds obvious it can be sometimes easy to forget to update a client
instance with the returned value before using it further.

Subject: RE: [flexcoders] Flex 1.5: AS2 serialization issue . Parent/Child data model implementation
Hello Flexcoders, here I am again...
I have set the logging level to Debug in the gateway-config.xml and was able seeing how data is sent on the wire.... However, I wasn't able to figure out what's wrong with the code.
I have pasted below the JAVA/AS2 data model and also the AMF log messages. If you can help me would be fantastic. I'm puzzled by the fact that the Individual object is serialized correctly and not the same happens with the PhysicalAddress( Individual's child object )
Thanks in advance,
Valy
1) JAVA DATA MODEL PARENT / CHILD ( one to many relation )
public class Individual implements Serializable {
/** identifier field */
private long indiId;
/** persistent field */
private Set PhysicalAddresses; // implemented 1 - many relation
/** default constructor */
public Individual() {
}
public long getIndiId() {
return this.indiId;
}
public void setIndiId(long indiId) {
&nb! sp; this.indiId = indiId;
}
public Set getPhysicalAddresses() {
return this.PhysicalAddresses;
}
public void setPhysicalAddresses(Set PhysicalAddresses) {
this.PhysicalAddresses = PhysicalAddresses;
}
public String toString() {
return new ToStringBuilder(this)
.append("indiId", getIndiId())
.toString();
}
public boolean equals(Object other) {
if ( !(other instanceof Individual) ) return false;
Individual castOther = (Individual) other;
return new EqualsBuilder()
.append(this.getIndiId(), castOther.getIndiId())
.isEquals();
}
public int hashCode() {

this.addrAddress = addrAddress;
}
public String getAddrPostalCode() {

&nbs! p; public void setAddrPostalCode(String addrPostalCode) {
this.addrPostalCode = addrPostalCode;

}
public boolean equals(! Object other) {

PhysicalAddress castOther = (PhysicalAddress) other;
return new EqualsBuilder()

Try changing the AMF Gateway logging level from "Error" to "Debug" in the /WEB-INF/flex/gateway-config.xml file and restarting the web app.The default logger implementation uses System.out to trace information to the console. Depending on your app server and how you start the process, this may appear on the command line or in a log file.

Subject: RE: [flexcoders] Flex 1.5: AS2 serialization issue . Parent/Child data model implementationPeter, thanks for the message. I' got caught doing other stuff for now but I'll give it a try afternoon.
Is there any way I can see what gets sent on the wire other than dumping the value object in the log?
Thanks,
Vali
