Raised as bug with Railo https://issues.jboss.org/browse/RAILO-2698 - this question should be closed
I am currently attempting to ObjectSave() on a rather complex Struct which contains instances of some CFCs among other data using the following cfscript (this is a test script I put together to reproduce the issue)
<cfscript>
thisState = session.objBasket.getState();
writedump(thisState); // dumps the object successfully
ObjectSave(thisState); // causes java.io.UTFDataFormatException
</cfscript>
I am getting the following error java.io.UTFDataFormatException (stack trace follows). Does anyone know of a way to fix this, or is it a matter of simply trying to use the wrong tool for the job?
Railo versions the error occurs on
Railo versions the error does not occur on

public TestObject function init(
required numeric levels = 0

}
The following 2 methods are what I am using in place of ObjectSave and ObjectLoad until the Railo bug is corrected. It seems to function up to a decent level of complexity.
// Replaces ObjectSave
private binary function serializeState(
required struct inState
) {
var strSerialized = serialize(arguments.inState);
return strSerialized.GetBytes();
}
// Replaces ObjectLoad
private struct function deserializeState(
required binary inState
) {
var strSerialized = ToString(arguments.inState);
var stcDeserialized = evaluate(strSerialized);
return stcDeserialized;
}
